My Obsession With My Sister (incest | brother/sister | mf | taboo)

**Part 1**

**The Panties Draw Me In**

This summer, I was back home after my first semester of college. It was nice to have my room to myself again for a while. The privacy would be nice after sharing a dorm with another guy for the past few months. The first thing I did when I came home was lay on my queen size bed that was much better than the full size in the dorm room. Just knowing I would be sleeping there for the next two months made me happy.

After getting unpacked in my old room, I went down to see if the family was home. It was just before noon so my parents were still at work. I went to check if my little sister Ashley was home. She must have been out also because her room was empty. Unfortunately, I would have to wait until later to catch up with the family. I had not seen them since the break in the winter.

Then I went to the bathroom to jerk off like any young man in his prime would do if they were home alone. In the bathroom, I took off my shorts and got some porn on my phone. Currently, I have been getting into porn with girls with big asses. While sitting on the toilet stroking my cock to the big booty babe on my screen, I noticed a pair of pink panties on the floor in a pile of clothes. They were bright pink panties made of cotton with a white trim that caught my eye.

After thinking about the panties for a moment in my dirty fantasy, I stopped. It was weird to be thinking about the panties that must have been my little sisters. I went back to watching my porn on the phone. My mind could not stop thinking about the sexy panties on the floor. I knew they were my sister’s, but I rationalized that I was only turned on by the panty aspect of them. It did not take too much rationalization to get me to reach for the panties on the floor.

When I picked them up I could feel the softness on my fingertips. The pink underwear was of high-quality cotton. Feeling the panties made my hard cock twitch in my hand. I started stroking faster as I rubbed the cotton fabric between my fingers. My cock felt harder than it normally had in the past. This time it was rock solid in my hand as I stroked myself on the toilet.

My sister’s panties were making me aroused more than ever. I decided that as long as I did not imagine it being my sister’s then it was not bad to use them to get myself off. That was all I needed to tell myself, before putting them up to my nose. The panties smelled amazing as the scent filled my nostrils. I had never felt so dirty in my entire life. The panties were too erotic for my young mind.

While sniffing the aromatic panties I continued stroking my hard dick. I jerked off until my throbbing cock could no longer hold in the sperm. My white cum sprayed out from the bright red tip. The load spilled out onto tiles of the bathroom floor. White ropes shot our almost two feet in front of the toilet as I drained my balls from the build-up of having a roommate for months. I used some toilet paper to wipe up my mess before flushing my sperm down the drain.

I decided that I would keep the pair of panties since I doubted she would notice one pair gone from the pile of clothes. When I got back to my room I figured I would have a few more hours before anyone got home. In my room, I locked the door to go for round two. It was rare I was ready to go a second round so quickly. This time I was even harder as I laid back against the headboard.

As I leaned against the wooden back on the bed, I sniffed the pink panties in my nose again. I stroked myself for several minutes while throbbing in my hand. Then I switched to using the soft cotton fabric to rub against my cock. They looked perfect wrapped around my decent sized dick. This was the best option for using underwear during masturbation.

It only took a few more minutes before my cock was edging to cum. I kept up the pace with the soft panties. My cum sprayed out across my stomach as I finally finished. The load was just as thick as I felt the warm sperm on my skin. Then I looked up at my pulsing dick to see the last of my load leaking down onto the pink underwear. Now I would have to throw them out because I can not put back her panties with my cum in it. For now, I stuffed them under my mattress before taking a nap.
