We’d just hang around together, play Nintendo, smoke his mum’s cigarettes. She was cool, 50 ish, divorced and made the best cups of tea, ha ha. O...e night, it was his birthday, we went to some place for a meal, just us three. We’d talked about sex before, I was a virgin, he’d done it twice. He went to the toilets, I decided I needed to go too. On the way out, there was a Durex machine. I didn’t know what they were, but he smiled and told me to get some I’d need them one day. The sign next to. It hurts."Jack and his erection didn't care what Sharon said. It felt good to plunder her tight hole with long powerful thrusts of his stiff cock. Sharon couldn't tell where the pain stopped and the pleasure began. "Owww! That's it baby. Fuck Mommy's ass good. Fuck me. Fuck me!"Jack did just that! He fucked his Mother's tight ass until he screamed with the most powerful orgasm of his young life. "Yaaaa! I'm cumming in your ass Mom. I'm creaming your tight asshole. "Yaaa!"Jack's body slumped. And after they'd done whatever they do to prepare it, a doctor, sitting on a stool between my sister-in-laws stirruped legs, pushed yours truly's baby making cream deep up inside her.What the fuck had we done?But that night, lying in bed and thinking of what we'd done that day, I'd realized something else. I realized I was happy Caitlyn was going to have my baby. I was happy it was my sperm that had been pumped inside her. I was secretly proud that for once it was the younger brother who was. Again my bum moved the entire length of her back in a to fro motion. Our buttocks slid easily over each other. I could sense that she was slowly loosening up. Now this was the moment. I turned her on the back and gave her a deep french kiss. I placed my fingers on her clit and rubbed it vigorously. The massage had such a relaxing effect on her that she offered no resistance to my wild rubbing. Her clit softened with each stroke. It became wet and started oozing heavily. I pulled her legs apart.
