One day I heard Chrissy in the shower. I went to the kitchen to make sure our parents had left for work. Then I got naked and joined Chrissy in the sh...wer. We were kissing and soaping each other up and laughing. At one point my soapy hand went down her ass crack and soaped her up. “Ohhh.” Chrissy moaned. “That’s a sensitive spot.” Then she did the same to me. Wow. When we were drying off Chrissy asked me a question. “Last week I kissed you with cum in my mouth,” she began, “You didn’t bat an. " What would you like me to do next?" she enquired."I need you to check through last years annual plan for anyinconsistencies with the report you've just drafted. It's in that boxfile up there.

Seeing them naked made him erect for the first time in his life and he took his cock out to look at it and then returned to watching his sisters and didn’t realize he was stroking his cock until he came and it surprised him and that’s when his head bumped the door and when Jen saw him. He told his mom that he knew what he did was wrong but he had never seen a naked girl before and was curious. Mom asked him if he was still curious and he began to promise to never do it again, but she stopped. I told her what all i had seen. she was tensed and pleaded me not to say this to anyone and specially my dad as he was a strict man and never indulged in affairs with anyone.i told her that i will keep quiet if i could do the same with her.she was not willing but reluctantly agreed and told me this will be first and last chance.i told her that “this is my first chance but surely not the last.She came and offered herself to me.it was uncontrollable for me. i went and grabbed her. she said”no.
