[F] another Halloween weekend story

On Friday I went to a frat party at the place I usually party, dressed as a vampire. The vampire outfit was pretty cool I think. I wore black hiking boots, leather pants, a dark kinda sheer croptop, black bra underneath, had my hair down, and put on some pale white makeup, with vampire fangs. The vampire teeth were expensive but really nice, they glue on to your actual teeth and stay on for hours.
My roommate and her friends went to this frat party with me dressed as zombies. It was really fun hanging out with them at this party going around pretending like we were all going to bite people. There was a lot of drinking games and most other people had on some cool costumes.
One of my FWBs who lives at this frat didn’t want to dance with me. So after a few drinks I went to dance by myself for a while in the common room, and even got to grind on a couple other boys. It was really fun. After a while my FWB came and got me from the dance floor and asked me to take a shot of tequila with him.
After that, he grabbed my hand and took me to the back kitchen. He pushed me against the wall and immediately started kissing me and making out aggressively. His hands went all over my body as we were making out. After a couple minutes he undid my bra under my shirt and lifted my top over my head, and pinched both of my nipples. Standing there completely topless in just my leather pants at this point, I playfully pushed him off me and walked further into the kitchen behind the island. He followed me, grabbed me by the hips and my butt, and pulled me close so I could feel his hard cock pressed against me, and started kissing me again aggressively. Then he tried to pull my pants down, which he almost did if they weren’t so tight. I think he clearly wanted to have sex right then and there. Even though I was really turned on at this point, I was feeling shy that maybe someone would walk in on us in the kitchen since there were so many people at the party. I was nervous about stripping naked and having sex right there, but I knew he was super turned on and I did want to make him feel good. So I got down on my knees and unzipped his pants. We made eye contact for a couple seconds before I wrapped my mouth over his dick and started sucking. It was a little tough to do because of my vampire fangs, and I know I accidentally rubbed the fangs on his cock a little too hard a few times, so I tried just sucking on his tip while massaging his shaft and balls with my hands. It didn’t take very long before he came in my mouth from the handjob/blowjob, moaning while throbbing in my mouth.
After that, I picked up my croptop from the floor and put it on while he was zipping his pants back up. He found some more liquor in the kitchen and we both took another shot. I don’t really remember why, but I didn’t put my bra back on at this point. We went back to the party. He went to play more drinking games with his friends, and I went back to the dance floor. Since I didn’t have my bra back on, people could totally see my nipples through the sheer croptop I had on.
I felt really sexy at the time about it. I love showing off and don’t always wear a bra in public anyway. But I do kinda have some regrets now because there are pics on IG where my nipples are pretty visible. On the one hand I do feel really sexy about it, but also worry who might be seeing or sharing those pics.. There were actually two other girls at this party who didn’t even have any top on, one of them had pasties on the entire party as part of her costume, and the other girl originally had an outfit but somehow ended up wearing nothing but her underwear after some drinking games.. but neither one of those girls ended up on the frat’s IG for some reason…
