My sister Rissa has been feeling a bit self-conscious about her body recently. Everyone at school keeps staring at her tits and telling them they are too big. While most girls wish they had large breasts, she’s afraid that hers are too big. Afraid that people might tease her because of them, she wears baggy clothes and refuses to do P.E. I caught her naked checking herself out and massaging her boobs. I decided to help her realize that guys love big tits and that girls can only be jealous of them. She asked me to touch her breasts and tell if I liked them. I wanted to show her that her huge knockers are extremely arousing. They were so soft that I couldn’t stop myself from getting an erection. I didn’t want things to get weird between us, but she was happy to see me getting hard. She invoked the “I showed you mine, now you have to show me yours” rule, and I had to oblige. Without bothering to hide her boobs again, she pushed me onto my back and felt up my dick through my pants. She didn’t look awkward or uncomfortable at all, so I decided to roll with it. She unzipped my pants and took out my penis. I didn’t know my stepsister was this perverted, but she started to give me a handjob. Her hands were soft and warm, and seeing her big tits made me cum after a few minutes.

STEPSISTERS CAN’T CONTROL THEIR TEENAGE SEX DRIVE:



I thought this would have been enough, but things escalated. Three days after that, I caught her masturbating with a vibrator. She was doing it in the living room. Anything for family, I thought as I started to finger my stepsister. She really was dry, but as soon as I went in, I could feel the wetness. Then my naked stepsister lay down on her back and told me to fuck her mouth. My cock was standing out in all its glory. She was insanely good, using her tongue to tease the tip of my dick. My cock was in her throat and my balls were rubbing against her soft boobs. She spread her legs and told me to put me into her. My cock was really throbbing by now and, since I had just fucked her mouth. I pounded deep into her pussy feasting on the sight of her big tits. She then slid her cunt onto my cock, put those big tits in my face, and got down to business. When I concentrated on her erect nipples, she grabbed my head and forced it to her boobs as she moaned and wet my cock with her orgasm. She even wanted me to fuck her doggy style like a whore. The sounds her big bubble ass was making and the sight of her asshole made me cum like I had never came before! I filled her little pussy with so much sperm! Since then, we’ve been getting closer and closer to having actual sex.
