We went into mom and dads master bathroom with the his and hers shower heads and all took a shower. I got to wash them both as the girl did not touch ...achother. after drying off we went into mom and dads room to the king size bed where I layed down with dawn and we began making out when I heard Julie say "God you guys I want some" and as me and dawn were kissing Julie began sucking my cock. I asked dawn "don't you care if I have sex with your sister"? And she said "I don't care do what ever you. Needles to say he was getting turned on and she was playing with his stiff cock. She spread her legs open and used her other hand to pull his hand to her groin. He took the hint and started to rub her through her damp knickers. Soon his fingers pushed aside the material and started to push into het cunt and rub against her clit. This mutual wanking went on and they both got more and more worked up. She unzipped his jeans and pulled his stiff and leaking cock out into the air. Then she carefully. As she was kissing and thanking Laura, Nan got up and demanded Lisa crawl to a nearby tree and bring a switch back in her mouth to use on her fat ass. Jenny could see her mother ass moving sideways as she crawled to a tree nearby, broke off a branch, and returned to Nan with it in her mouth.“Good doggie, show your daughter how a good little white whore presents her ass for punishment.” Nan demanded her.Lisa immediately got on her back and lifted her legs above her head till her toes touch. Then Justin feels his member throb as his balls go tight and heave upward. He closes his eyes as cum starts to shoot up into the air. His sister just keeps pumping his shaft until she has milked it all out. He quickly tucks his member back into his shorts, turning just enough in his seat to watch her hand finish of Zate’s curved cock.“Ah, shit!” Zate suddenly yells as his cock starts to shoot cum out.Both Riley and Justin jump from their seats, laughing and running for the exit. They run.
