I had to make a small survey for my science class at college about sexuality and since I have my stepsister, I decided to ask her some questions about sex. I was pretty surprised about her answers, I had no idea she was so open about sex. She loves porn, she loves to masturbate and she loves talking about it, given me steamy details about her sex life. I was trying to keep a straight face, but I was getting a massive erection under my pants! When I asked her about her favorite sex position, she told me it was reverse cowgirl, because it lets her squirt everywhere! Fuck, I had no idea my stepsister was a squirter! I was curious about this squirting stuff, and she was more than glad to show me! I couldn’t believe it when she started taking of her clothes right in front of me! She had beautiful small titties and a juicy bubble butt and was not ashamed at all nor felt awkward about stripping naked in front of her very own stepbrother. I was so blown away! Thing is, for her to squirt, she needed to get fucked first, so she got down on all fours and suggested I fuck her doggie style, you fucking believe that? There I was, fucking my very own stepsister, watching her pushing her juicy bubble butt against my cock! The hot babe straddled herself on top, impaling her dripping wet pussy on my throbbing member, riding my cock until she started squirting, gushing pussy juices from her snatch all over my cock and the bed sheets! I kept fucking her in missionary position, I already had all the information I needed for my survey, I just wanted to keep watching my stepsister squirt! “Cum on my face!!! cum in my mouth!” she screamed. She sucked my cock as fast as possible. I was already ready, and within seconds of this I released a huge wad of cum all over her face, and still kept going. It came out more and more.
