It took me a long time to discover that my step sister Tanya had developed a crush on me which has since turned into something else. It all started about four years ago. Tanya and me are about the same age, I'm just over six months older than her, and we were going to the same high school at the time.
One Saturday morning I got home from basketball practice. Both our parents work and our older siblings had moved into their own flats so Tanya and I were alone in the house as per usual. I'd noticed lately that she had gotten into the habit of wearing nothing but a tee shirt and panties. Anyway when I got home she was in the kitchen fixing herself a latte and asked me if I wanted one. I had to try hard not to get a hard on cos Tanya was looking extra sexy. She's about 5'3', 100 lbs with long dark brown hair and blue eyes. It was obvious she wasn't wearing a bra cos her 35b breasts were kind of bouncing around and her nipples really stood out. Then I noticed her panties were riding low and I could make out a dark triangle above the bulge of her mound and groove down between her thighs. And when she bent over to pick something up off the floor I could see a lot of the top of her arse crack. My cock naturally reacted and started throbbing and stretching my shorts.
I made some excuse and raced upstairs to my room. Once safely inside I dropped my pants, knelt at the side of the bed and had a good wank. Once I'd squirted a load of cum I started thinking about things between Tanya and me. I really liked her and we were good friends. I wondered whether she was coming on to me which I had to admit I didn't mind. She'd had boyfriends and I'd had some girlfriends I'd gotten to second and a memorable third base with but having my step sister as a girlfriend? After a while I decided that it was my imagination and that Tanya was going through some type of girl thing. Finally I relaxed and headed to the bathroom to get my shower.
Once in the shower I started thinking about Tanya again. This time I let my imagination go. My cock grew hard at the thought of those perky tits. Again I wrapped my hand around my cock and started jerking off. How would her nipples feel? Were her areola wired to her clitoris as I'd read in one of my mags? Then I started thinking about her cunt. How tight would her slippery muscles feel wrapped around my throbbing cock? I closed my eyes as my body started to tingle and shake. What would she taste like, I hadn't yet tasted a girl's cunt but I was keen to try it out. What would it be like to squeeze and rub that gorgeous arse as we fucked? I grunted and shuddered with the exquisite pain as I touched my sperm crack. Finally with a groan I let go a big wad which splattered against the wall tiles, just as Tanya opened the door and stepped naked into the shower.
