Susan had seen what they were doing at the pond. His astonishment loosened his tongue."How do you know what we do at the pond?" I followed the twins t...ere yesterday. I saw what you and the boys did and I saw what the twins did too. Do you do anything else with the twins?" Uh, no. We don't even talk to them about it. We just sort of got started and now we do that every nice day."Both of them ran out of things they dared to say to each other and sat there blushing. Susan wanted more, she sensed. My fingers found my little clitoris and began to pinch, stroke, rub. Even uncovered I began to feel warm. As I rubbed, I remembered the sight of his penis in Mom's mouth and then began to imagine the sight of that same piece of meat in that unimaginable place.The more I rubbed, the more my puss tingled. Finally, or so it felt, the tingling covered my entire body. And then something happened. It was as though I had been hit by a bolt of lightning, yet I was still alive. Ah, so that's what Mom. We kissed and fell asleep in each other’s arms.Unbeknown to me, my wife had started to read the impregnators blog as well. One evening I caught her looking after I arrived home from work earlier then usual. “Busted” I shouted with a smile on my face. My wife turned around and like me before could only stammer. I pulled up a chair and sat next to her –“so what’s the latest”? I asked. My wife smiled and said –“that wife he fucked last time has just told him she is pregnant”. This was so serial,. As custom had it I already had my cock out and was wanking it off for the benefit of the prefects.I have a thick cock and a fine pair of heavy balls. I made sure not to come for a week so I was well ready for Rosie.The two female teachers brought up a basket and Rosie proceeded to strip off. And oh what a lovely sight was revealed.Rosie still had a lot of puppy fat, which I found endearing. Full tits which were firm but had a little bit of bounce to them.Surprisingly dark hips. Rosie clearly.
