So you better do as I say. SHOW.ME.NOW I was stunned that my sister was asking such a thing but I really had no choice. So I took my right hand and st...rted stroking my soft penis. She was standing by my feet so she had a full view of me and I had a full view of her in her white skirt and tight blouse. It didnt take long before my cock was fully erect and I started stroking it trying not to look at my sister. I tried to forget she was in the room but no matter how hard I tried I knew she was. Just before her nineteenth birthday she was knocked up with his fourth c***d. Her tits were huge and heavy with milk. She was still nursing her last c***d and he nursed too. He had women take care of the babies and c***dren and all she had to do was nurse and bare him more babies. Soon as she knew she was knocked up he then began eating her pussy and having her suck his cock. Some nights she would have a baby attached to a tit as he ate her pussy. Then he would suck the other tit for the warm. Tina was moaning, "Plant your seed in me. Make me have your baby."This sticks in Dave's mind and he goes into the bathroom to shower and jerks off to what he has just seen. He gets ready for work quietly all the while watching this free show on his bed. Once he is done and ready for work Tina raises up off of this cock slowly, letting it slap back against his stomach, and turns to Dave saying, "This has to be the best present you could have ever given me." She reaches out and grabs the cock. "My wife rolled her eyes. "I still think you're cute because YOU remind me of HIM!"The two of us laughed, which got JJ to start laughing again. And moving in, I nuzzled my son's cheek from one side while his mother nuzzled him from the other. This, of course, provoked more squeals and giggles. And I already knew I would never get sick of the sound.Eventually, we let JJ go to crawl after an empty water bottle that had become his favorite toy. He retrieved it, and then after seating himself.
