By the time Cassie and I got to the second party we were already pretty tipsy. It was after 1 AM and I was ready to go back to the dorms but Cassie said she heard Tom would be at this house, so we went. All week I had heard about Tom and how they flirted last weekend and how this weekend they'd certainly fuck. I was excited for Cassie, so long as she planned to go back to his place. I didn't feel like finding a place to crash, and I didn't think they'd want me there unless I was planning to join in. (which I wasn't.) Cassie and I had talked about a threesome before, but never seriously, and we had never experimented together or with any girl. I hoped that tonight she would go to his place, and I'd have the room to myself for some me time.
The second house party was crowded, and with the usual crowd. Cassie anxiously scanned the first room, and I moved toward the kitchen to find more alcohol. In the kitchen there was a group of guys taking shots and I moved in. They each called me cute or sexy and I took advantage of it by drinking their alcohol. After a few shots, Cassie entered the room and joined us. She didn't find Tom, and she found out he'd already left with someone else. In typical, non-jealous, free-spirited Cassie fashion she immediately joined us in drinking. The guys seemed to love all of the female presence and we both loved the attention we were receiving.
"So, how do you girls know each other?" one of the guys asked.
"We're roommates," Cassie answered, "this is my best friend!" She hugged me, letting her hands fall and rest on my butt. We laughed, and the guys seemed to enjoy it.
Another guy looked us up and down and asked, "Have you two ever messed around? Gotten a little... dirty?" He laughed a little saying it, but I knew he really wanted us to say we have.
"Oh, only every night. I used to just touch myself, but with this one around, I never need to." Cassie answered in a sexy, flirty tone. I blushed, and laughed a little too hard.
The guys must have known this was a joke, but one asked us to prove it.
All the sudden, Cassie grabbed my face and kissed me. I kissed back, and tasted the liquor on her tongue. She lowered her left hand to my ass and squeezed in view of the guys. My hands moved from her hips to her waist while she squeezed and smacked my ass playfully. The guys cheered and we separated. I laughed a little nervously, and wondered if she was blushing as much as me.
The guys asked us back to their place, but we agreed we were tired and ready to go back to our dorm. On the walk back, I told Cassie how surprised I was at what she did. She laughed.
