--------

After a moment, mom seemed to regain her composure, as she let go of hugging me, and without looking at me directly said, "Rinse yourself off and get dressed."

I did as instructed, grabbing the showerhead and spraying myself over with water, and rinsing around my cock and balls to get the remnants of semen from my last cum load off.

Then I stepped out of the bath, grabbed a towel from the rail and dried myself off for a moment with my back to mom. I turned around to say I was off to get dressed and saw mom looking down at my now limp dick and balls. She had an intense look on her face, almost like she was mesmerised by my prick.

"Dry your cock properly," she said, watching me. I was a little surprised at her saying this, but did as she asked, rubbing my cock and balls over with the towel.

I caught a glance at her as I did so, and saw her lick her lips. It excited me again to see her do this, but not to the extent that it had any effect on my dick, just yet!

"Actually, don't dress. Just put your gown on without anything on underneath and go downstairs and eat breakfast. I'll be down in a few minutes after I rinse off as well," she added.

With that she drew the shower curtain across and I heard the sound of water spray over her.

I threw my towel in the linen basket in the bathroom and walked naked into my room. My house-gown was on a chair in the corner. As I walked over to pick it up I passed by the full length mirror in my room and just stood for a moment looking at myself nude. My chest swelled and I felt confident as I did so. I had finally fucked mom. Twice, in fact, and boy it had felt great. Now, I wanted more. I wondered if she would let me carry on doing that as part of our sessions. I just couldn't get enough of her voluptuous, sexy body!

I pulled the gown on and went downstairs. I sat down at the kitchen table with some orange juice and cereal and started eating. As I eat, I wondered what we would do today and what mom would wear for me to keep me 'stimulated' as she put it.

After about 20 minutes, I heard mom come down the stairs. I was a little disappointed to see she had herself completely covered up in a white cotton bath gown. She was holding a blue document folder in one hand.

She didn't look at me as she came in, but just started to get her breakfast ready.

I didn't say anything. There was silence for a while.

Then mom came over and sat opposite me and started eating some toast she had made, and sipped on a cup of coffee.

She looked at me and said, "Now, Jacob, what we did this morning must be a complete secret between us."

"Yes, mom," I replied, in a serious tone.

"Did you enjoy it?" she said, much to my surprise.

"Yes, of course," I replied. "Bit of a strange question," I added, truthfully.

"Well, I was wondering if you felt guilty that it was not right."

"It felt right, mom," I replied honestly. "It just felt like something natural to do, like all the other stuff we've been doing."

"I'm glad you are comfortable with it," she replied firmly. "I just wanted to make sure. I should have restrained myself though, I think," she added, "But over the past week, since the doctor said I should help you get samples of your cum, seeing your nude body, and you appreciating mine, well......you've awakened a part of me that has been dormant since your father left." She paused for a moment, looking into her coffee cup.

"But, your penetrating me means that we haven't managed to collect proper samples today and that's why I think we must not do it again. It's just too hard for you to pull out in time."

I felt a bit disappointed, but just nodded in agreement, so as not to make it an issue.

After mom finished eating, she said, "I've brought the record of your semen measurements taken from the measuring beaker. You know I've been keeping a note after every session."

I nodded. I had not seen the record sheets so far, and keenly looked over as mom pulled a couple of sheets out from the document folder.

Come over here so you can see better.

I moved my chair around so that I was sitting next to mom and we faced the same direction. She put the sheets on the table in front of me.

Mom had pencilled in amounts in several boxes in columns, each column representing a day. As I looked through what she had noted down, I could see that most of my cum measurements were somewhere between 25 and 40 millilitres each time. But I noticed there was no total for each day.

"Mom, do you mind if I just add up what I've been producing each day?"

"No, I guess not," she replied. "I think the doctor was going to do that anyway."

I got up for a moment and grabbed a calculator from the kitchen drawer, and then sat down again next to mom.

I started totting up the amounts for each day. There were 6-7 cum loads per day noted.

It took a few minutes and mom watched me whilst I added them up.

Then when I'd added up each column so that the figures for each day was done, I looked closely at the final figures.

It appeared that even though the amounts I had been producing varied a little each time, the daily amounts never showed more that 5-10 millilitres of variance.

"That's interesting," I said finally.

"What is?" Mom replied.

"Look, can you see that the amounts I'm producing each day aren't that much different? That means that even if we miss a collection or two, we could probably just work out an average."

Mom smiled at me. "I see," she said. "So what your saying is that we can fuck once or twice a day without worrying about collecting you're cum to measure are you?"

I blushed, hearing mom be so blunt.

"Er...actually I hadn't thought of it that way," I replied, truthfully, as I had been engrossed in working out the figures and what they might mean. "But, I suppose that's one of the outcomes of the results so far," I said, trying to sound all serious and scientific about it.

"I see," said mom. She looked at me hard in the eyes. "So are you saying that we could even go a full day without collecting and measuring your cum?"

"Er.. well.." I replied, "I don't think we should do it too often, but we could do that occasionally, as long as we did take normal collections and measurements on other days until the doctor has worked out what is going on with my condition. Otherwise we might mess up working out the averages."

"Ok," replied mom. She seemed to have a bit of a mischievous look on her face now. I couldn't quite make out what she was thinking, but my dick was starting to twitch a bit under my gown.

"In that case Jacob," said mom, with an intense look on her face, and I also noticed her cheeks flush, "Why don't we forget about collecting samples today in the semen beaker. You have got me very aroused since morning, and I think that today, I will help you to cum as naturally as possible, and in return I want you to help satisfy me too. How does that sound?"

I gulped, not quite believing what I had just heard, and my dick was now tenting up my gown. I could not hide it, and mom saw this, as I was sitting right next to her.

I just nodded, still not knowing quite what to say.

"I can see your cock is in agreement," said mom with a wide smile and then a giggle.

"Let's go upstairs to my bedroom," she said.

She stood up and as I did so too, my hard cock was still pushing my gown up below my waist.

Mom giggled again. Well that looks a bit silly, let's make you more comfortable and untie your gown. And with that, she pulled on my belt untying it, and my gown opened from the front, partly exposing my nakedness underneath, and my erect dick popped out.

"That's better," said mom, and grabbing my hard on said, "Come on." Mom walked in front of me and pulled me along behind her holding my cock like it was some rod attached to my body!

Fuck! I couldn't believe it! It was like mom was taking me upstairs for sex! And she had said her bedroom this time, not mine. Fuck, Fuck, Fuck!

Mom gently pulled me along the hallway and then up the stairs, and then finally let go of me as we entered her bedroom.

Mom's bedroom was bigger than mine and she had a king-size bed as opposed to a double in mine. She also had an en-suite bathroom like me. All along one wall opposite her bed were fitted cupboards with sliding doors, which all had full length and width mirrored fronts on them, so that the entire room almost looked double in size as you stood in the room looking at the mirrored cupboard wall. For someone who I had always thought of as very prudish until now, mom liked mirrors a lot, and she also had a very large one on the wall over the head end of her bed. Her bedroom had a beige coloured carpet and a large fluffy white rug at the end closest to the bay windows, where there were also two cream coloured single sofa chairs. Mom had a very luxurious bedroom!

As we entered the room, mom closed the door firmly behind us.

"Sit on the end of the bed facing me," she said commandingly.

I sat down as instructed at the end of the bed so I was facing the mirrored wall of cupboards. My gown was still open at the front and my dick had for a moment gone down a bit from its fully hard state it had been in a moment ago.

Mom now stood in front of me in her white bath robe, her back to the mirrored cupboard wall.

"Now," she said, "After so many days of having to collect your cum in a measuring beaker, today we are going to just help you cum as naturally as possible. Maybe that will help sort out your medical problem too. We are going to fuck like a normal couple, all day Jacob. Do you like the idea of that?"

I blushed deep red, hearing mom talk like that.

"And I want to hear you talk dirty to me, and I want you to fuck me as hard as you can to satisfy me. I think I deserve that, after helping you out all week. Now, tell me you want to fuck me."

"I want to fuck you mom," I said, a little meekly.

"Louder," insisted mom.

I want to fuck you mom," I repeated, a little louder.

"Louder, and more firmly."

"I wanna fuck you hard mom," I said.

"Better," she added. "Now say it in a more dirty way."

I paused for a moment, thinking, and then said "I'm gonna fuck your ass off mom, I'm gonna fuck that wet juicy cunt of yours which you let me fuck earlier today and I'm gonna do it hard and long, and all day until I make you scream."

"Even better," said mom. "But make sure you talk like that when you fuck me. And you may call me all sorts of names that men like to use. Don't be shy with me, it's all part of the enjoyment and satisfaction. Can you think of any names to call me?"

I swallowed. I was now starting to lose my inhibitions as I responded to mom's requests and teasing.

"Er...S...Sexy...b...bitch."

"That's good. More."

"Teasing bitch. Cock-sucking bitch. Prick teaser. Cock loving whore." I turned deep red again saying this all, but it soon wore off seeing mom was looking pleased as I said these words to her."

"That's right young man. I am a cock-loving whore. I love the taste of dick and I love fucking, and I want to be fucked like a dog, and if you want, and if you please me enough, you can fuck my ass too! Your father used to love that! Would you like to fuck my asshole?"

My dick was now raging and I stood up. I couldn't wait anymore as my lust was at full blast.

Mom untied her robe and let it fall to the floor. She was completely naked underneath and her voluptuous body came into full view, her breasts were looking full and swollen and her nipples protruding, indicating her aroused state.

"Let me taste that wonderful cock of yours," she said.

Mom immediately fell to her knees in front of me and took my hard dick into her mouth greedily. She sucked on it almost like some sex starved animal! She lapped at my balls and I could feel and hear breathing heavily on me as she sucked and licked me. She let me dick slide along her face and cheeks like she was worshipping it, and then engulfed the entire cock-head again into her warm wet mouth.

Seeing her like this was really getting me turned on and my dick was straining hard as she sucked on me. I grabbed her head and held it almost like I was face fucking her as she sucked on me.

After a few moments of this she stopped, stood up and said, "Let's get on the bed. I want you to lick me too whilst I suck you off."

I lay down so that my head was at the end of the bed nearest the mirrored wall, and then mom straddled over my face, so that her glorious open butt cheeks hovered above me. What a fabulous sight was above me! Her wide fleshy buttocks opened to expose her cunt lips which were hanging down, and her pinky brown puckered asshole were being brought down to smother my face for my pleasure!

As mom positioned her backside over my face, she firmly planted her knees and legs on the bed next to my chest, and began to suck my dick madly like before.

I licked and lapped at her cunt and ran my hands up over her butt cheeks and lower back. God, this was so good!

I loved the smell of her pussy and ass, and for a moment I let my tongue slide deeply into her asshole, stretching it wide as I did so.

Mom was still sucking on my dick wildly, and although the cum was beginning to rise in my balls, I was managing to not cum too quickly as I wanted to make this last as long as possible.

I let my saliva pour into mom's pussy and asshole in turn, and I licked and lapped at each, as she wriggled her butt into my face in response, and I continued kneading her fleshy buttocks at the same time. Man, I was in butt licking heaven!

Then, finally I felt the cum rise in my balls and I shouted out to mom, "I'm gonna cum soon."

Mom stopped sucking on me and said. "I want you to cum in my mouth, so I can taste your lovely spunk, but I want you to watch me do it. Let's change positions."

With that, she moved her legs off me, got off the bed and knelt on the floor at the end of the bed again, sideways onto the bed and the mirrored cupboard wall.

I stood in front of mom and grabbed my hard on, slapping it on her tits and then her cheeks few times before she took the shaft in her mouth again. Changing positions had put a pause on my cumming, but only for a moment, as her mouth was doing wonders on my dick again. I looked at the mirrored wall and watching my own mother kneeling on the floor with her full hanging tits looking so sexy, sucking me off like she was doing for my pleasure, sent a wave of lust through me, and finally I felt the cum rise in my balls. After a moment I shouted out, "Ahhhhh.. AHHHH....... AHHHHHHHHHHHH......., as I came, spurting wave after wave of cum into mom's welcoming mouth.

Mom managed to take the first few spurts in her mouth and swallow my cum, but either she was a bit out of practice taking cum in her mouth, or I was producing a hell of a lot this time, because on the third of fourth cum wave, some of it came out of the sides of her mouth. Then, as my final few cum waves came, mom, stopped trying to swallow it, and just opened her mouth and stuck her tongue out a little, letting me see my cum dribble down her chin and onto her boobs. Fuck, what a sight! My cum was dripping down her chin in gooey strands! Finally, having stopped my spurting, mom, wiped my dripping cock head along her cheeks so that my spunk smeared her face like some cream. Then she rubbed the cum that had dropped onto her tits into them and then licked her fingertips, as if to show me how much she enjoyed it!

"Ooh, that's lovely, Jacob. I do love the taste of cum, and yours is especially nice. I haven't told you before, but after taking your samples using the semen beaker and measuring it, I would always swallow and drink some of your cum from the beaker. That's why I know it tastes so good. I love it!"

"Fuck! Did I hear right? Mom had been swallowing my cum from the semen beaker after our sessions! Jesus!

As I looked down at her, with my spunk over mom's chin and face, and some stringing down towards her boobs, just thinking about mom drinking my cum from the semen beaker seemed to send a second shot of life into my dick again and I became slightly hard. Mom noticed and went back to sucking me and managed to get another wave or two of cum into her mouth before I went completely limp, and then started licking and lapping my cock head to clean it up.

Finally, I just collapsed back onto the bed in a heap, and in the high of my orgasm.

"Mmmm...that was lovely," said mom, getting up from kneeling on the floor and walking over to the bedside cabinet. Her large melon like tits wobbled sexily as she did so.

Mom picked up some tissues from a box and wiped my cum from her face and boobs, dropping the tissues into a wastebasket next to the cabinet.

"Give me a minute whilst I clean myself up properly," she added, and then walked to her en-suite bathroom. I watched her wide meaty ass cheeks wobble and jiggle as she walked. Man, what a sight!

After a few minutes mom came back into the room, beaming a wide smile and lay herself on the bed, with her back straight against the cushioned headboard.

"Give yourself a wash too Jacob, and then come and lie next to me," she said.

I got up off the bed and started walking to the bathroom like mom had done.

"Nice ass," she said chuckling, as I went.

I responded with a slight giggle. I remembered mom liked my ass too.

Mom had a much nicer bathroom than mine. It had a large bath at one end and at the other a spacious 'walk-in' type shower. The shower area was very roomy -- I'd say you could fit three people in there easily, and it had all manner of jet sprays as well as the traditional shower head type fitting. The nice thing about this was that you could just walk in, pull the frosted glass door across and start showering -- no messing about standing in a bathtub or cramped shower cubicle -- it was very roomy and spacious.

I walked into the shower, turned the jet sprays on, which hit your body from several angles, and soaped and rinsed myself all over quickly, including my cock, balls and ass crack. I knew mom liked me to be especially clean. In less than two minutes I was done and drying myself off.

Then, throwing my towel in the linen basket, I walked back into mom's bedroom. My now limp dick was waving in front of me as I walked, and my balls were flapping a bit.

I saw mom look down at my crotch area as I walked in.

"Is my sexy son all clean now?" she said teasingly, and with a cheeky smile.

"Yep, sure am mom," I replied, as I clambered on the bed so I was half sitting, half lying next to her with my back up against some pillows.

I looked at her naked body next to me and felt like touching her. She must have sensed my desire and said, "You can touch me if you like, whilst we talk for a bit."

I moved my right hand over mom's stomach and up to her boobs. I squeezed her right boob gently and tweaked the thick protruding nipple with my thumb and forefinger. Then without asking, I bent my head down and licked all around her nipple and gave it a gentle suck

"Ohh...that's nice baby," she said in response.

I was still far from being able to get hard again, but it was nice just to touch and caress mom. I moved my hand down her body again, over her stomach and then down over and along her pussy mound. I looked her in the eye as I did this, wanting to see an approving look from her. She did not disappoint me, saying, "Oh yes, touch mommy's pussy, play with it. Put your finger in if you like," and then closed her eyes and pushed her head back to enjoy the sensation. I moved my middle finger along her pussy mound, over the hairs there until I felt the line of the opening, and then gently pressed in, pushing my finger into the moist flesh there.
