Should have got caught months ago

God, I can't even remember what I was about to say. Something about the light. Anyway. That was the whole stupid night right there. Me in those panties, the ones with the little pink bow on the front that kept riding up every time I moved. I bought them online three weeks earlier and kept telling myself I'd throw them out after one wear. Never did. The fabric was already stretched weird from how many times I'd pulled them up and down in front of the mirror, checking if the back disappeared between my cheeks the way I wanted. They didn't look good, just... cheap. Pink. Obvious. My roommate came home early from his shift. I didn't even hear the front door. He just stood there in the hallway, keys still in his hand, and I was in the bedroom doorway wearing nothing else. We stared at each other for maybe four seconds before he laughed, quiet, like he couldn't believe it either. He didn't say anything clever. Just walked over and picked me up like it was nothing. My legs went around his waist on instinct, same way they do when you're trying not to fall. I remember the wall light was still on, the one with the ugly white shade, and how warm his hands felt under my thighs. He was already hard. I felt it through his jeans first, then he pushed them down one-handed while he held me up. The head of his cock was darker than the rest of him and it pressed right against the thin strip of panty between my legs like it knew exactly where it was going. I kept saying his name. Not loud, just enough times that it started sounding stupid. He didn't answer. He just shifted his grip, got one arm under my ass, and worked himself inside me slow. The panties stayed on the whole time. He didn't even bother pulling them aside properly, just pushed the fabric to the side with his thumb until it was digging into my skin. I could feel the elastic stretching and snapping back every time he thrust up. My left foot kept kicking out behind me because there was nothing to brace against. The other one was tucked against his hip, toes curled. I remember looking down once and seeing the little bow on the panties still sitting there, now wet and crooked. It looked ridiculous. I almost laughed but it came out as a sound I didn't recognize. He fucked me standing up until my arms started shaking from holding onto his shoulders. Then he turned and walked us over to the bed without pulling out, laid me down on the messed-up sheets, and kept going. The headboard was knocking against the wall by then. I could hear the TV still on in the living room, some commercial playing. It felt like that sound was coming from another apartment. After he came he stayed inside me for a minute, breathing against my neck. Then he pulled out, wiped his dick on the sheet next to my hip, and left the room. I stayed there with my legs still open, the panties soaked and twisted, one of them half-off my hip. The wet spot underneath me was already going cold. I should have locked the door months ago.
