"Do you wanna fuck my boyfriend?"
If I'd had a drink, I probably would've spit it out all over her in surprise.
It's not like I didn't want to fuck Katie's boyfriend. Rick was pretty good-looking, for one. He was a little taller than average, with dark hair just long enough to be a little shaggy. He also had a killer smile. Katie had also, of course, told me everything about him, so I knew he was a great lover. Not that I needed her to tell me so; Katie was my roommate, and I could hear them go at it sometimes. So yes, I very much wanted to fuck her boyfriend. In fact, the only reason I wasn't already fucking Rick is that he was dating Katie, my best friend, and that was the one rule I found myself sticking to as I gave in to my sexual desires more and more: never with anyone Katie was seeing or seriously interested in, and her exes were only fair game with her explicit approval. I did not want my growing slutty nature to ruin my best relationship.
"Maybe I should rephrase," she giggled when she saw my face. "Do you want to fuck him with me? You see, his birthday's coming up..."
I nodded in understanding. "And he wants a threesome. With me specifically, or is that your idea?"
Katie shook her head. "The whole thing's my idea. Well, we've discussed fantasies, and being with two girls is a big one for him. But that was a while ago. I want to surprise him. And I want it to be you."
It had been almost a year since Katie and I had first began exploring each other sexually. It started fairly innocently, but grew fairly passionate for a while, before cooling down into something we were both comfortable with. Living together, we'd found plenty of time and opportunity to play with each other, but we realized that as much as we loved each other, we were both after something else. That doesn't mean we stopped playing around, though. We'd still play whenever the mood struck.
We'd never involved anyone else, though. We had talked about it several times. Never with anyone in mind or any plans to make it happen. Just idle chatter about how fun it would be with a guy or another girl with us. I'd been in a threesome before, but with two guys. It would be my first time with a girl and a guy. The fact that it would be with Katie just made it so much more appealing.
Of course, I agreed.
When Katie texted me that they were on their way to our place on the night in question, I quickly turned off the lights in the house and got myself ready. The plan was for Katie to tell Rick that I was out for the evening and they'd have the house all to themselves.
I heard them come into the house as I waited in my dark bedroom. As Katie had promised, they quickly made their way to her room. Ever impatient, I made my way into the hall and waited just outside her room, listening in. Only dim light emanated from her room. There were general noises of a couple making out. Some words were said, but too quietly for me to hear. I found myself wanting to peek around the corner to see what was going on, like some innocent schoolgirl curious for a glimpse. I didn't want to ruin the surprise by being spotted, though.
Finally, I heard Katie say, "I'll be right back, baby. I've gotta get your last birthday present. Now when I come back, you better have nothing on but your boxers."
"You got it," came Rick's excited response.
I made my way back to my room, and Katie joined me there. "All going to plan?" I asked. Katie nodded and giggled, closing the door. "Still want to do this?"
"More than ever," she answered.
"Good," I said before kissing her deeply. "Now get ready!"
Katie quickly stripped naked and then put on the outfit we'd decided on. I was already in mine. Once she was ready, we made our way into the hall again. I waited just outside again, as she moved into the doorway.
A gruff, "Wow," was all I heard from inside.
"Are you ready for your present, baby?" Katie had her teasing voice on. I can only assume Rick nodded. "Are you sure?" Another pause, then, "Are you sure you're sure?"
Finally, I heard the response. "Fuck yeah I'm ready, Katie! Now come on over here!"
"But I'm not your present," she said, still teasing.
"You're not?"
"Well, I should say that I'm only part of your present. Here's the other part." She reached out and took my hand, guiding me into the room.
Christmas lights around the room provided most of what little light there was. Katie kept them up year-round. A couple of lit candles were on stands on either side of the bed. Rick lay on his back, propped up on pillows. As promised, the only clothes he had on were a pair of gray boxers that didn't do anything to hide his erection.
He obviously wasn't expecting anyone else. His eyes widened and he made as if to cover himself before the reality of the situation hit him. He finally took in the sight before him.
Two girls stood in the doorway. One, he was intimately familiar with. The other, he almost certainly had thought about being intimate with. We were wearing matching outfits; Katie was in black, and I was in white. We were both in heels and thigh-high sheer stockings, with matching lace bra and thong. I'd moved in close once I came in, my hands on her waist had turned her to face me, though we both had our heads turned toward him.
"What do you think? Do you like your present?" I nuzzled her neck as she asked and slid a hand down to her ass cheek, though I never stopped looking at Rick. I'd thought maybe the shock of me being there might've softened him up a bit, but he was still clearly rock-hard as he took in the sight.
"You mean... both of you?" Words weren't coming easily to him.
"If you want us both," I said. "If not, I guess you could just watch." I kissed Katie's lips softly, playfully, putting on a show. I squeezed her ass, and she slid a hand to my breast. Both activities on the side clearly visible to Rick. We broke our lips apart and both looked at him, waiting for a response.
"No, no," he stammered. "I do want you. Both. Both of you."
"Good," I said as I gave Katie's ass a solid smack. I broke away from her and sauntered toward the bed. As I crawled onto the bed, climbing over his legs, I softly said, "Because I've really been wanting a good look at the cock Katie won't shut up about." I ran my hand up his thigh and over the tent in his boxers. My hand ran along his hardness before I tucked my fingers into the waist of his shorts and began to slide them down. I glanced up at his face, and he was looking over me at Katie, still wanting reassurance that it was okay.
I returned my focus to what I was doing and watched his cock leap out of his shorts. I slid them all the way off before settling in. His cock was quite nice. It was a little thinner than most I'd had, but a little longer as well. I took it in my hand and stroked up and down before giving it a good lick.
"I think I see what all the fuss is about. You were right, Katie." I kissed the tip before letting it part my lips and slide into my mouth.
I felt Katie's hand on my ass. "You don't think I'd lie about something like that, do you?" Her hand slid down and began to rub my pussy through my thong. I moaned softly into Rick's cock. "My, you're quite wet already! You might be more excited about this than Rick is!"
