I can feel her massaging my balls and I move my tongue to try to fuck her with it as deep as I can get. She presses back into me to go even deeper. Sh... is so wet that most of my face is covered in her juices by now.All of the sudden she jerks to the front a bit and sits up to position her asshole right over my mouth and I get right to licking it. I can feel her hand on her clit going very fast as she is nearing her orgasm. Then she comes while squeezing her legs, gripping my dick very firmly. Wow..what big those are………i become mad lokking at mu siter partcularly when she is rubbing the soap her part. I came my room and masturbuted….. From taht day i keepon watching of her bathing whenever i get chance…but onething i came to know that …my Sister is not having sex regularly…..because generally comes home late..that is around 11:30 and after having a dinner he goes to bed…He is aged about40 years…One day iam watching TV in hall room..My siter asked his husbend to come early as she. It looked shiny…It was something really huge. I had seen many hard black cocks in my life; but this one was the biggest I had ever met. It was hard as a fucking rock…It was dripping pre cum and all I had to do was slide my hand around that big head a few times and he was slick as could be. I then worked my hand down the shaft just admiring and stroking it.I could not get my long fingers around it all, since it was so thick.I looked at him in the eyes and leaned on his crotch, licking up and. She ran her fingers all over it again and again. She kept it in her mouth. First the tip and the most of the dick inside in her mouth and sucked for half an hour. But there is no sign of me to orgasm. She shouted at me to fuck her now. So I slowly inserted the tip of mine inside her. Sensing the incest we are breaking into made her instantly CUM. I dig deep in side her cunt with my long lengthy pipe and drilled inside little by little. She shouted with joy. I pumped taking the whole tool.
