I pulled down her pants and all of a sudden I realised that I had no condoms thinking well I'm fucked when all of a sudden she says be a dear and grab...my bag I have condoms I thought to myself fuck yes there is a god, I popped it on my cock and without hesitation slammed my cock in her wet pussy it was crazy wet i ain't k**ding she was dripping down her legs I started slapping her arse and she moaned a little. So I started going deeper and every time the moans got louder with ten minutes left. Dad has her ass cheeks spread and I rub her ass hole, teasing her and as she begs me to finger her ass, I reach over and pull the dildo out of mom and shoves it up her ass, dad asks “what the fuck did you, her eyes are the size of dinner plates and she looks like she is in a state of pure pleasure “, I reply “ that I shoved moms dildo up her ass and I am working it in and out of her ass”.All we can hear sis saying is “don’t fucking stop and cum inside me”, I look over at mom who is fingering. I slowly placed my hand in her breast above her pajamas.Wow, it was so soft. I can’t believe that I am feeling my own sister breast.After some seconds I slowly pressed it.She didn’t react. This gave me courage and I placed my leg upon her, my dick raised and I was feeling her ass upon her panty.She used to wear soft lingerie. I started enjoying her other breast slowly. After some time I slept.The next day everything went normal and I waited until night.After everyone slept the same thing. She whispered "that was nice" and kissed me on the lips and got out of bed and went in her bathroom. The next morning I woke up and she was sleeping with her bra and panties back on. I quietly got out of bed and went in the bathroom to take a bath. I filled the tub and got in. I kept thinking about the night before and got hard again. I lathered some soap on my hand and started rubbing my dick. Than there was a knock on the door, and Shelly asked "can I pee"? I covered my hard on with a wash.
