I was sneaking into my step sister's (Kylie Rocket's) room while she was showering. Kylie's gorgeous sudsy body turned me on, I'm not going to lie. She didn't see me so I sneaked into her closet as she talked to her girlfriend about getting ready to have phone sex with her long distance boyfriend. She hangs up with her when he calls and I continued to watch her masturbate and moan for him while she writhed on the bed. I stepped out, my erect cock in my hand. She didn't notice as I stroked it in front of her at first until she opened her eyes. She continued to talk and moan for him as she looked right at me! My heart jumped and I felt a lump in my throat as the most brutal embarrassment burned my face bright red.
I ran away to my room as she finished. A few moments later she came to my room, calm and collected. She claimed she wanted to talk and that she wasn't angry. She noticed my cock was still hard and noted that it must be uncomfortable and that what he was doing was wrong. She told me that this wasn't the first time she caught me. I had no idea but the memory was seared into her brain, it was "life changing," she said. My heart sped with excitement as Kylie expressed how disappointed she was that I ran away because she wanted my cum all over her but she only wants it under the right circumstances, where she doesn't give me permission, she wanted to be surprised. She's a exhibitionist, she likes to be watched. A few days later and I see her go into her room and texting her boyfriend to setup another phone sex session. I followed her as she got undressed in her room. She spotted me just as he called but they have end up having a fight so she closes the door on me. Later on I catch her undressing again as she started to masturbate, moaning for me as I walk in the room. She saw me stroking myself and then stops rubbing herself and sucks me off. She wants me bad at this point as she bent over and I slide my now wet cock inside her from behind. Thrusting faster as she moans louder as she has me lay down so she an climb on top of me. She then laid down on the bed and spread her legs for me so I could slide right back in as she rubbed herself and then I came inside her.
