After showing Alyx around campus, I went to my afternoon classes. I found myself daydreaming quite a lot, imagining all sorts of lewd things I'd do to my little sister. Visions of her hot, tight pussy constantly floated around my mind and I found myself shifting my legs through the day as my dick awkwardly rose to attention.
It was half past four in the afternoon when I headed back home. As I passed by one of the university's gyms, I stopped and thought about actively working out again. While I had been on the track team in high school, college life had made me a little more sedentary. Not that I was out of shape, my weight was just a little under 180 pounds and I was trim enough for my height. Still, I was beginning to lose some muscle definition. My six pack was pretty much a four now, for example. A bit of lifting and jogging would get me back to my ideal weight in the lower 170's. Needless to say, I would never have given any of it a second thought if it wasn't for Alyx. As it was, the only thought I had was of me pounding my little sister's pussy, and wanting to be in the best shape of my life for that occasion.
Admittedly, my thought process was more than a little muddled with lust, but I was enjoying it. After looking around the gym a bit, I hurried back to my place. I would be happy with another handjob from Alyx, but I wondered how open she was to putting my cock in her mouth. I had gone down on her earlier in the day, maybe I could persuade her to just give it a few licks for starters.
With thoughts of soft lips moving up and down my shaft, I opened the door to the room and found... a note. It seemed Alyx had come back earlier than me, but had to leave soon after to keep an appointment with her guidance counselor. She wrote she'd be back before six. Which left me with a rock hard cock for more than an hour.
I kicked off my shoes and socks and proceeded to lie down on my bed, a sigh of frustration escaping my lips. Well, I thought, this was as good a time as any to surf for some porn. As I propped myself up, my hands fell on something. A pair of black, cotton panties. Still warm. I leaned over the edge of the bed and found a matching bra on the floor. I shook my head. Alyx was still pretty careless with her clothes. On the other hand, she seemed to be comfortable enough here to treat my place just like her room. Which definitely had its benefits now, I thought, lying back down and admiring the tiny panties in my hands.
I'd never been that interested in my sister's panties back in our younger days. We shared a bathroom on the second floor of our parent's house, and it was a rare day when there wasn't at least a bra carelessly strewn on the floor. Never mind her room, which she kept open for the most part. The most contact I'd ever had with her underwear was nudging them out of the way with my foot. Yeah, I occasionally looked a little longer at the lacier or more risque ones and I'd be a liar if I didn't admit I checked her cup size as it grew over the years, but I'd never actually done stuff like masturbate with them or sniff them.
