My god... Her lung capacity was incredible and she did not have a single contraction. She was really impressed with me, but I was a bit uncomfortable ...ue to something I was feeling while we were underwater. She gave me a chance to recover my breathing, reassuring me that it was my first time and after hearing it, I wanted to please her more.Not only that I touched her breasts and body while we were under. I kissed her nipples and sucked them. She felt like she was enjoying it more, and I didn't. From the spankings and now this assault to my balls I have become fully erect. She keeps squeezing my ball sac and pulling them down from my body, like she's trying to pull them off. She reaches under me and starts to play with cock. She has applied more soap now and I am rocking back and forth fucking her slippery fingers. At the same time I can feel the pain from her gripping my balls. I'm about to lose it and cum, but I must concentrate. She has rules about when and how I come. I can't cum. "How about instead, you have to run naked down our block all the way to the stop sign and back while singing the national anthem at the top of your lungs?" She had a wicked smile on her face and seemed pretty proud of the idea."But what if it gets back to mom or dad that we were doing this? They'd be pissed!" Jake replied. "Alright then you can wear your mask so at least you can deny it was you," Lindsay said. "Now are we gonna do this or what?" Jake stared briefly at his sister's exposed. Even when she married my best friend she still wouldn’t talk to me; no, no, I mean him, wouldn’t talk to HIM.Anyway, they stayed together. His willingness to try so hard endeared him to her. His brother was a little more resilient, having forced himself to make a couple of children by the biological insemination method (and one with a spoon of semen inserted... ), and he was asked to help. Seems proper sex was regarded by some as lucky for producing good babies – which of course means boy.
