When I was 17 my parents divorced and both got remarried, I would spend week days with my mum and tom my stepdad and weekends with my dad and krista my step mum, my step mum was a lot younger than my dad he was 38 and she was 24.
My dad worked the 'graveyard' shift so he was out from 9pm till 9am, one night I pretended that I was sick so my (then) boyfriend could come over and Krista wouldn't 'annoy' us. at 10pm he came into my room and we started fooling around, he was sucking on my breasts when Krista knocked on my door, I quickly shoved him under my bed and covered myself with my blankets pretemding to sleep. She whispered my name quietly but I didn't answer. She sat on my bed and started to stroke my forehead, the moonlight coming through my window made her look like an angel and I was really wet from my boyfriend foolin with me, I pretended to stir so I could look at Krista I realised she was naked I almost jumped up! my heart rate started to fasten and I got wetter down there, she slowly moved her hand down my body and played with my nipples but kept looking at me to make sure I wasn't awake she leant over my body and licked my nipple I groaned in pleasure, she realised I was awake and stood up, I stopped her. She looked at me and said 'oh you want me huh?, well then' she ripped my sheets off my bed and jumped on my body she began humping me over and over I couldn't stop moaning then she turned around and shoved her finger into me so I grabbed her ass and shoved two fingers up her wet pussy. We humped each other and went into multiple orgasms. PERFECT!
