After about 5 minute rest, I fucked her again mercilessly and this continued from 11am – 5pm. Even though she was in excruciating pain initially, sh... eventually developed tolerance and now enjoyed my fast and deep thrusts. That day I fucked her over 8 times (within six hours) in three different positions (Missionary, Doggy of course, and Boa), none lasting less than 15 – 20 minutes. We had only two such intimate sessions and before she left for better studies abroad, she made me feel real. My hand was all over her long smooth legs, creeping up her thighs, then on her soft round bottom through her bikini. I felt her gently thrusting her cunt against my bulging rod. Then to my amazement she started to stroke my erection through my shorts with her fingertips following the ridge where my knob meets my shaft. I decided to be more adventurous too. I tickled her just above the top of her bikini briefs, then I slid my hand down inside the front of her bikini. I felt her cunt hair and. She was having big boobs. I made her sit in the chair and I sat in a stool nearby and showed her the key board mouse etc.But she was not looking at the keyboard but at my crotch where my cock end was taking a peep. While showing her the mouse and how to hold it I brushed her boobs many times and I was getting an erection. She did not resist but I am sure she must be leaking from her pussy.My cock when coming to an erect condition cannot be contained in the little space provided to it in the. After having a glimpse her butt my teenage horniness took over although I had never thought of Aunt Susan as anything but my aunt but now I was getting a terrible erection while thinking about her ass and I didn’t know what to do. My older sister, Julie kept using the bathroom (yes, that time of the month) it was on her last trip when I mentioned that I needed to use the bathroom, Aunt Susan told me to use her bathroom as I’m walking into the bathroom I noticed a hamper overflowing with dirty.
