Measuring My Cum - pt9

... lips with it, which were hanging down. God, her open pussy was so tempting, and just centimetres away from my cock head. I just wanted to shove it straight in! Then, to my surprise, mom, who must have been so turned on my what I was doing, said, "Ok, Jacob, I can't stand this anymore. Stick it in my cunt, but don't cum inside me. We need to catch your cum in the beaker still!" Fuck! I couldn't believe it! This was music to my ears! Without further hesitation, I pointed my straining dick directly at her gaping pussy hole, and shoved it in. "Ahhhhhhhhh..." I cried out in ecstasy, feeling mom's pussy walls grip hard onto me. I pulled back instinctively, and then shoved in again. "Ohhh...yess," I said. Mom was also now groaning in pleasure as I did this. I carried on pumping her, now a little faster, as I grabbed her hips for support. The feel of mom's pussy around my dick as I penetrated her, in and out, was wonderful! Imagining fucking was one thing, but actually doing it was a hundred times more pleasurable! I was in the throes of ecstasy now and didn't care about anything, let alone making sure my cum went into the semen beaker. I think mom was also in an extremely heightened sexual state as she was moaning and groaning with pleasure, pushing her pussy back into me as I shoved my cock in at each thrust. "Fuck me, yes!" she said out loudly. I was now moaning loudly too, and I just couldn't stop myself cumming quickly, it being the first time, no matter what happened next. I ...

Mom responded with a huge moan of pleasure too, as I carried on spurting inside her. Finally after what seemed like ages, I stopped cumming and felt my cock go limp and I collapsed on the bed next to mom, who was now laying on her front with her eyes closed. I had finally fucked mom and cum inside her too! It felt like ages before either of us spoke. Mom broke the silence by saying in a quiet tone and without looking at me, "What have we just done?" I didn't say anything for a few moments. Then I replied in a quiet tone too, "I couldn't stop myself, and neither could you I think." There was silence for a while again. "You're right," she said after a few minutes. "Never mind, it's happened now. I guess it was bound to happen at some point. We'll have to just get on with it. And we've missed getting a sample." Mom paused for a moment, as if thinking. Then she said, "Maybe we can work out an average sample based on all the results from the past week. But, you must promise me Jacob, that you will never tell anyone about what we've just done. Not ever." "I won't mom," I replied sincerely. "Never." "Good, I feel a bit better about it then." She paused again. "And maybe if we do it again to help you to cum, it won't matter so much now, as we've done it once," she added, much to my surprise. Fuck! That sounded unbelievable! Mom was ok for us ...
