I had barely been able to concentrate on my lessons at college that day. I'd spent much of it with a semi hard-on just thinking about mom wanking me off that evening, and the sight of her in her underwear. By late afternoon, the ache in my balls was more than normal. I needed to cum, big time.

When I got back to our house, my heart was beating fast, not knowing quite how things would pan out this evening. Mom's car was parked in the driveway. She was home already -- she normally got in before me, because of the hours she worked.

She was in the kitchen, and called out to me as she heard me come in and slam the door shut.

"Jacob, come in here."

I walked down the hallway into our kitchen.

Mom had her head down mixing something in a bowl.

"I've been thinking about our little arrangement," she said, looking up at me, and without any 'Hello' or 'Hi'. "We'll have to organise our evenings so that we have one session as soon as you come in, one just before bedtime and then fit one in somewhere in between depending on what we've both got planned for the evening." I didn't like the tone of her voice. She was in one of her moods it seemed, and it was the last thing I expected or wanted when I got home.

"This is all very inconvenient for me Jacob. I hope you appreciate what I am doing for you," she continued, sounding really pissed off. Maybe she had been simmering all day at work, thinking about my problem and what she was having to do to help me.

"I do mom," I said, trying not to let her get to me and appease her. "It's only for a couple of weeks, hopefully," I added.

"Are you sure you've not been lying to Dr. Taylor and me about being with a girl and catching something?" she said accusingly. "If I find out after all this that you have, young man," she continued, in a threatening tone.

"Honestly, mom, I haven't," I said a little desperately, "I honestly don't know why I've got this...er...problem," I added looking directly at her.

She looked at me hard in the eyes from across the room in silence for a few seconds, and then seemed to mellow a little.

"Ok, then," she said, more calmly, apparently pacified at my response, and looking back down at the bowl she was stirring.

"Are you going to have a shower?" she said in a more relaxed tone, but sounding like she was being made to do a chore.

"Yes, mom," I said. I normally had one first thing, when I got home in the evenings.

"Well, as we need to get three specimens each evening, I think we can do one first thing when you come home, whilst you are showering. It will save time," she said.

My dick became alive as she spoke, despite the fact we had almost argued a moment ago.

"Ok," I said, and blushing a little. "I'll...er...leave my bathroom door open for you."

"Give yourself a good wash all over, first," she replied, "And then give me a call. I don't want to come in before you've had a chance to clean yourself all over properly," she continued.

"Ok, mom" I replied and turned back into the hallway and ran up the stairs. My dick was straining in my pants again.

I pulled off my jeans, t-shirt and sweater quickly, kicked of my sneakers off and removed my socks in double quick time. I wanted to cum, and cum soon -- my balls were really aching.

I left the bathroom door ajar and got into the bath, pulling the shower curtain across at the same time. Turning on the shower, I gave myself a good wash all over, including my balls and semi hard cock.

I had one of those shower's that were positioned over the bathtub with a detachable head, so you could either take a proper bath or stand at one end of the bathtub and shower, or use the head attachment in your hand. It was nice having my own bathroom attached to my bedroom.

On finishing, I turned the water off, opened the shower curtain, and shouted out loudly to mom, so she could hear me downstairs, "I'm ready mom."

As I dried myself off with a towel whilst standing in the bathtub, I thought about mom coming in here in her bra and panties, and my cock became fully hard. I was desperate to cum, but I didn't want mom to see me like this as she walked through the door. I was still a bit embarrassed about her seeing me so easily aroused, so I decided to hang the towel casually in front of my legs, hoping she would not notice that I was trying to hide my erect dick.

I heard mom come into my bedroom and then she knocked on the bathroom door, which was ajar about two inches.

"Come in," I said. My heart was beating fast.

Mom came in. She had not undressed and was still wearing the half sleeved blouse and skirt, which I had seen her in downstairs. I felt a bit disappointed. She had the semen-measuring beaker in one hand.

She looked me up and down and saw I was holding the towel, covering my crotch and legs partly. My dick jerked up again, seeing mom standing just a few feet away, with me being nude in the bath in front of her.

"Why are you holding that towel?" she said, and grabbed it. As soon as she snatched it from my hand, she saw my boner sticking out.

I blushed, still not used to her seeing me like this.

"Your cock gets hard easily doesn't it?" she said, not taking her eyes off it, and looking a little mesmerised by it. My stretched cock head, with the piss slit showing, pointed straight up towards her.

"Er...well... I guess...it's cos I'm quite young." I said a little embarrassingly, trying desperately to think of an excuse. "I can't really help it," I added, being truthful.

She licked her lips. I'd not seen her do that when she had wanked me off before.

I blushed again, not quite sure what to make of seeing her do that.

Then, looking back up at me she said, "Ok, just follow my instructions. We'll have to do things a bit differently as you're standing up, rather than lying on your bed."

"Ok," I replied, compliantly. I still wanted to cum bad. "I think I'll be quite quick this time," I added, wondering if she would take her blouse and skirt off for me.

"It looks like you don't need much stimulation, but I'm going to take my blouse and skirt off anyway. I don't want them to get stained just in case we have a mishap, as your standing," she said.

Then she turned around so her back was towards me and pulled her top off over her head and threw it on the clothes hamper in the corner of the bathroom. I could see her bra straps now. She was wearing a cream coloured bra.

Then, still with her back to me, she unzipped her skirt from the side and let it fall to the floor. My dick jerked up. I saw she was wearing matching cream coloured panties and I could see the shape off her round, full buttocks, tightly held in by them. I took a hard breath in. The panties seemed to be slightly more modern and shapely than the black ones she had worn before, with a bit less fabric, and seemed to be tighter into her ass crack too. She looked really sexy!

Then she stepped out from her skirt, taking one step backwards and bent down forwards to pick it up.

Fuck! What a sight! She was sticking her ass right out back, towards me with the material of her panties catching in her butt crack. She seemed to hold that pose for ages and then stood up, and threw her skirt on top of her blouse on the clothes hamper.

Then, she turned around, looked at me and then down at my dick. I saw her bra from the front and noticed that this bra, like her panties, seemed to have a bit less material than the black ones she had worn before, and was also more modern looking. Still, it covered her largish boobs well, so I could not see much of them.

My eyes then wandered down to her crotch. The material of her panties was quite thick and wide there, so I could not see much, not even any pussy hair. I looked up again quickly, so as not to appear like I was staring.

"Have you cleaned it properly?" she said, looking at my erect dick.

"Er..yes," I responded feebly, and feeling all hot and bothered seeing her like this.

"Let me make sure and give it a quick rinse," she replied.

She grabbed the showerhead, which was detachable from the wall bracket, and turned the water on, directing the spray onto my hard cock and balls. She gently stroked me along the shaft, and then my balls.

"Turn around," she said.

I didn't know why she wanted me to do that, but I did it, following her instructions. She could now see my naked butt properly, for the first time.

"You have quite a nice bottom Jacob," she said spraying the water onto my ass cheeks and giving each buttock a good rub up and down with her free hand. When she touched my ass, my dick jerked up. I had never felt so hard before.

"I think I need to cum mom," I said, a little desperately, but trying to sound as cool as possible.

"Turn around again."

I faced her again, my dick pointing directly at her face again. I was rock hard.

"Good, we won't waste much time then, as you are so ready," she said.

She grabbed the semen beaker from the washbasin where she had placed it, and said, "This time, I'm going to wank your cock towards me."

As I stood in the bath with my dick pointing out over the side, mom bent forwards slightly so she was looking down at my dick, held the semen beaker with her left hand, and then with her right hand, started pulling on my dick towards her, pointing the head of my penis into the beaker. She was holding the beaker about level with her boobs, so it looked almost like she was wanking me onto them and her bra, if the beaker had not been there. Fuck! This was a real turn on!

As she bent forward, I could see the top of her boobs better as they hung down in her bra whilst she stroked my dick. The feel of her hand squeezing and stroking my hard-on was fantastic.

I knew it would not be long before I came now. Then, all of a sudden she stopped wanking me and said, "Jacob, I think we might have a problem like this. I don't want you to cum on my bra and stain it, just in case I miss catching your cum for any reason. I think it's better if I take it off."

I could believe my ears. Mom was going to take her bra off! Fuck!

She let go my dick, put the semen beaker down and started unclipping her bra from the back.

My heart was racing big time, watching her do this, and my dick raged up in response.

She didn't look at me, and without any fuss, whipped it off, grabbed the semen beaker and started pumping my dick again, concentrating hard on it.

I looked down and couldn't believe my eyes! I'd never seen boobs before in real life and just seeing the large fleshy, milky-white globes of each breast was incredibly arousing! And as I stared, I saw that mom had wide pinky-brown areole, about two inches across on each, and large nipples to match! Fuck! Her boobs looked amazing, and my dick seemed to harden even more!

I stared open mouthed whilst mom's boobs wobbled and shook below me as they hung down whilst she wanked me off. That was it. I shouted, "I'm cumming," and mom tightened her grip on my prick and pointed it firmly into the beaker, as I came in thick, creamy spurts, again and again.

"Uh...uh...Uhhhhhhh....." I blurted out as I exploded.

"That's right Jacob," said mom encouragingly, as she milked my dick, pulling and squeezing on it. My cum waves seemed to last for ages, until finally I felt I had no more to give, and mom finally let go my limp dick.

I had to sit down on the edge of the bath facing her and closed my eyes for a moment. That cum had felt so amazing and I was on a real high.

I came to my senses after a few seconds and mom said, "Look at this."

I looked at the beaker and saw my cum had almost reached the half way mark. It looked like a lot.

But my eyes did not linger on the semen beaker. They went back to the amazing sight of mom's gorgeous large tits. They were 'hangers', and big ones. Fuck! They looked so hot! I felt like touching and sucking on them.

I tried not to look as if I was staring hard, but it must have looked a bit obvious.

I think mom realised I was looking at her boobs and became a bit self conscious and said, "Ok, that's enough for now. I'll go and make a note of this quantity and then finish getting dinner ready. Give yourself a quick rinse again and come down to eat," and with that she turned, grabbed her bra and clothes, and began walking out of the bathroom towards the hallway, which was through my bedroom.

As she did so I could not take my eyes off the sway of her ass, and the way the flesh of her butt cheeks wobbled and wriggled as she did so. The material of her panties seemed to catch in her ass crack and I don't know if it was my imagination, but her hips seems to be swaying more than I'd ever noticed before, as she walked.

I could never have imagined that I'd see my mom topless, with just her panties on, walking out of my bathroom and bedroom like that in front of me. This was all still incredible!

I cleaned up, put on some clothes and then sat on my bed for a moment, thinking about what had just happened. I was trying to make sense of it all. This was all a real turn on for me.

My mind went back to the way mom had been whist in the bathroom. I thought about the way she had looked at my hard dick at first, seemingly mesmerised by it, the way she had licked her lips and then bent over, showing me her ass as she picked up her skirt, and then asking me to turn around so she could look at my butt and give it a feel, and then finally, her taking off her bra and showing me her boobs. It all had been so fucking hot!

Yet, before all this, she had been angry and had a go at me whilst in the kitchen, saying it was all very inconvenient for her! How odd!

It was a real turn on, the way mom had been in the bathroom, and maybe she was just doing those things to just stimulate me, but somewhere in the back of my head I started to wonder whether she was doing those things on purpose, because she was getting some secret thrill out of it.

As far as I knew mom hadn't been with another man since dad left three years ago. She must have sexual feelings too. Had she got angry in the kitchen because she was feeling guilty about what she was doing, or because she was getting some sexual pleasure out of it and feeling guilty about that?

If that was the case, I maybe I could be more adventurous and suggestive in our sessions, in stages, as long as I didn't go too far each time. And perhaps I shouldn't feel so self-conscious of my body in front or her -- if she was getting some secret thrill out of it, then I needn't be shy. As these thoughts came to me, I felt a bit more confident about our next session, and about showing her my body. I think I was becoming aware of the power of my own sexuality.

I looked over at the clock on the wall and realised I had spent a while going through my thoughts. I went down to help mom get the dinner ready. She was dressed properly again and doing her chores. Nothing more was said for a while about our session earlier. Mom asked me how my day at college had been, and I asked after her work. We were just like 'normal' at home in the evenings. But I kind of looked at mom's body differently, and more lustily as she moved around the kitchen.

She seemed more relaxed than earlier.

Then, just before eating mom said, "Tell me when you need to cum again."

I nodded and got the plates out.

About half an hour after eating, I felt I was ready, as my balls were aching a little.

"I think I'm ready now," I said to mom whilst she was reading in the living room.

Without looking up at me she said "Ok, we'll do it on your bed again like yesterday. Get yourself ready and I'll come up in a few minutes."

As I lay naked on my bed waiting for her, my dick started to get semi hard thinking about mom's body again. And I felt a bit more relaxed about my own nudity in front of her now. I hadn't been able to feel up mom's ass during our session in the bathroom and I was looking forward to that, assuming we would do the same thing as before.

Soon, there was a knock at the door and mom came in, holding the semen beaker. She was wearing the same cream coloured bra and panty set she had worn earlier. The top of her tits swayed a bit in her bra as she walked towards the bed. My dick responded by jerking up.

"We'll do like we did this morning and last night," she said and angled herself so that her butt was more accessible to me. "You can touch my bottom again if you like."

I was waiting for her to say that, and started squeezing and stroking her buttocks with my left hand whilst she bent forward slightly and stroked my hard-on. I felt a little disappointed I would not see her tits like before, but felt comfort in that fact that she might take her bra of again in the bathroom tomorrow.

Mom's ass felt exquisite. I felt like I would last a bit longer this time and not cum so quickly. It might have been because we were repeating our routine and it was not so new.

After a couple of minutes, mom seemed to notice I was lasting a bit longer than before, and she looked back at me and said, "Not so quick this time, I see."

"ER...no mom," I said hesitatingly, "But it won't be much longer I think."

"Well, maybe this will help a bit "she said, "I haven't got all evening for this, and need to get you going" she said, a little sternly.

Then she did something amazing I hadn't seen before. With her free left hand, she moved it behind her, and pushed the fabric of her panties into her butt crack a little, so more of her butt cheeks were showing, making it look much more sexy. Then, even more surprisingly, she wriggled her ass at me a little, as if to tease and stimulate me.

Her full backside looked wonderfully sexy as she did that. It did the trick, my dick responded by jerking much more firmly in mom's hand as she stroked me.

I increased the swirling motions of my hand on mom's ass, squeezing a bit harder, and touching the flesh a bit more around her ass crack, which I had not done before, and I felt the cum rise in my balls.

"I'm gonna cum soon mom," I said after just a few moments of playing with and watching her butt like this.

She grabbed the semen beaker with her free hand and placed it into position.

Then, taking a bit of a chance, I rubbed the two middle fingers of my left hand which was stroking her ass flesh right along the material of her panties that had gathered inside her ass crack, pushing it in a bit myself and feeling the walls of the insides of her buttocks a little. Mom jerked her ass a little as I must have touched a more sensitive spot, but did not object.

That was it. I came, "Ohh....ohhhhh....Ahhhhh...." I said out loud. Like before, waves of cum filled the semen beaker as mom milked and pulled on my dick, making sure every last drop went in to it.

As I relaxed back on my head onto the pillows, I let go of stroking mom's ass and she straightened herself up.

"Well, done" she said, in quite a matter of fact way, "Get cleaned up. I'll go and note this measurement down and get on with my other stuff."

And with that she turned and began walking out of my room.

My eyes went to her butt as she did so. The material of her panties was still caught up in her ass crack a bit -- she had not adjusted it properly and made her ass look so damned hot! I was almost hypnotised by it -- watching her buttocks wobble as she walked away. I wanted to lick it, but didn't know if ever that would happen. Then she disappeared from my view.

I cleaned up, dressed, and made a few phone calls to friends using the phone in my bedroom. Then I decided to do a bit of college homework for a while.

I think Mom had decided to potter about in the garden for a while and water some plants, although it was almost dusk.

At about 10pm, she came into my room and said, "I want to get an early night, can we get the last measuring session over with now?"

"Sure, mom I said" turning around from looking at my computer screen on which I had been doing my homework on.

I thought she might go out of the room and ask me to get undressed and give her a call when I was lying on the bed, but instead, she said, "You can undress in front of me, I've seen plenty of your body now. You don't have to be shy with me in that regard."

My dick, which had been limp, came alive in my pants, hearing her talk like that.

I pulled my t-shirt off over my head, and as I started to unzip my jeans, mom pulled off her blouse at the same time and unzipped her skirt, stepping out of it. She placed her clothes on one corner of the bed and I did the same.

I stood there in my boxers with my dick semi hard, as mom stood on the other side of the bed facing me in her bra and panties.

I pulled my boxers down, exposing my semi hard on. She saw it, but did not say anything. Then, I had a brainwave. Mom had seemed to want to look at my butt a bit earlier when we were in the bathroom, so before clambering onto the bed, I turned around so she could see me naked from the back, and walked over to the window.

The curtains were already pretty much drawn, but there was a slight parting in the centre.

"Just want to make sure no one can see anything," I said trying to sound helpful.

I made sure mom got good look at my naked back and ass as I reached up and precisely positioned the curtain edge. Then, still facing the curtains, I took a step back and bent down pretending to move something on the carpet, so that my butt was pointing at mom, so she could see it in all it's glory.

Then, I straightened up, turned around, and with my semi hard cock bobbing up and down in front of me, climbed on the bed, lying face up in my normal position. I had avoided eye contact the whole time I'd done this, but as I rested my head on my pillows, I looked up at mom's face and I was sure her cheeks looked a little flushed, like she had been blushing.

"I'm glad you are being discreet, Jacob," she said with a little smile, and seemingly, composing herself. I know we are doing this for medical reasons, but we can never be too careful. As I mentioned before, we shouldn't discus this with anyone except Dr Taylor. And I certainly wouldn't want any of our neighbours to know what we are doing," she added.

"Sure, mom" I replied reassuringly. "I understand."

Then, seeing that mom appeared pleased with me and more relaxed, I decided to try the idea I had earlier about maybe pushing things a little further in our session, just to see how far mom might go.

As mom turned to position herself as normal, with her butt a little towards me, I said, quite innocently and with some hesitation, "Er...mom,...before we start, I was wondering...er...well...actually... I thought maybe to help me cum a bit quicker, as it took a bit longer last time...if...er...you....you might take your bra off again. I'm sure it would stimulate me...er...you know...a bit more." There, I'd said it!

There was bit of a silence, as mom seemed to ponder over what I had said, looking directly at me.

Then, looking all serious again, she said, "Well, I do agree it took a bit longer for you to cum last time, and I don't want this to go on longer than necessary. As you have already seen my boobs in the bathroom, it probably won't matter if you see them again, when I stimulate you on the bed."

It was music to my ears, and my dick responded at the thought. Mom noticed, but didn't say anything.

I wondered if I could go a stage further.

"Thanks, mom" I said. "That should help a lot. Would you mind if I gave them a light touch like I do with your butt? I might cum really quick then, and it is for medical reasons," I added, taking a chance.

Still keeping a straight face and in a business like manner, mom looked at me and said, "Ok, but just lightly."

She moved her arms behind her and began unhooking her bra. I couldn't wait to see those glorious globes again and this time, touch them.

Mom pulled her bra off slowly, revealing her large hanging boobs.

I couldn't help but gasp a little again and my dick raged up to a full pole.

Mom looked at my dick, and then back at me, and smiled a little and said, "Well, I can see an immediate reaction."

"You've got really nice boobs mom," I said, trying to sound appreciative and thankful, which I really was. "I hope you don't mind my saying."

"Thank you dear. No I don't mind. Your father used to like them too," she said, all business like. She moved her chest towards the pillow end of the bed more so I got a direct view. Her boobs were now just about foot away from my face. I had never been so close to them before, and got a much better look at them, than in the bathroom. "You may have a light touch and squeeze," she said, "Just to get you going."

I took in the fullness of her milky white flesh of her tits as they hung down, noting the wide pinky-brown areole surrounding each thick, almost bite-sized nipple, and instinctively put both my arms up, lifting and cupping each full breast simultaneously, one in each hand. They filled my palms completely as they hung into them, as my hands acted almost as bra cups.

I gently let go and then tweaked each nipple gently, with the thumb and forefinger of my hands and rubbed along the areole surrounding each nipple, feeling the slight raised bumps on the flesh there.

My dick was now raging and jerking up continuously.

"I think that's enough," said mom after a moment, and noticing the way my hard on was going. "Let me get your sample now."

I lowered by hands from mom's boobs. I desperately wanted to suck on them, but knew better than to go any further today. Maybe, much later in our sessions mom might agree, but I didn't want to push things too far right now.

Mom angled her butt again for me, and I started feeling it up again through the material of her panties. I think she knew by now I liked feeling up her ass, and she wriggled it a few times again for me like she had done in our earlier session. She did it so nicely and sexily, almost pushing her ass back into my hand, that for a moment I wondered if she was enjoying it too.

Mom leaned over me, her large boobs hanging down over my stomach towards my groin, and began pumping my cock with her right hand. Then, without my asking or suggesting anything, copying what she had done in our earlier session, moved her free hand back behind her and pulled the material of her panties into her butt crack a little so that her butt cheeks were more exposed and looked more sexy.

She must have guessed I would cum very quickly with all this going on, because after finishing toying with her panty fabric in her ass crack, she immediately positioned the semen beaker correctly with her free hand, with my dickhead pointing into it as she pumped it with her other hand.

She was right. The sight of mom topless, her sexy boobs hanging down above me and my feeling her wide ample butt as she wriggled it sexily for me, tipped me right over the edge. In almost 30 seconds of this, I came, spurting thick waves of thick spunk into the semen beaker again, as I grunted satisfactorily whilst cumming.

"That's good Jacob, a nice specimen," said mom in a satisfied tone, as she wiped bits on my cum that were on her fingers into the beaker. She stood up straight, holding the beaker up to the light, showing me how much cum I had produced again. She looked really sexy as her large boobs hung down on her chest.

I gulped, a little out of satisfaction, as well as from the way mom looked standing in front of me.

"Well, I think I'm off to bed now" she said with a smile, "After noting down this measurement." She bent forward and gave me a kiss on the cheek. Her boobs touched my chest momentarily as she did so. "Goodnight, and be ready for our morning session."

"Goodnight mom" I said. "Thanks, I do appreciate your help with my problem," I said trying to sound as grateful as I could, and meaning every word.

As mom turned to walk out of my bedroom, my eyes went to her hot ass again. The material of her panties was still caught in her butt crack. She didn't seem to mind, and her hips swayed again. Looking at her like that, a thought crossed my mind about another suggestion I could try making next time, which might let me enjoy that wonderful ass of her's even more.

The ache in my balls had completely gone as normal after cumming three times over the evening, and I settled down to sleep, still thinking of mom's hot body.
