It was my birthday. We'd had a small celebration at my girlfriend Laura's apartment. About 20 friends, good beer, good weed, lots of laughing and music. As I kept drinking, she would walk by occasionally, pull me close and whisper in my ear, "Don't get TOO drunk ... I have plans for you later."
She was very pretty, a brunette with pale skin, brown eyes and full red lips. At about 5'8", she was a former cross-country runner and softball player, curvy and full through the hips. She had large, soft breasts that had small pink nipples and swung beautifully when she rode me.
The party had been fun, but now it was late. Most everyone was gone. Just our friend Erin remained, sitting next to Laura on the couch, both of them sipping wine from separate bottles. I was in a chair across the room, just about six feet away, pleasantly buzzed and knowing that as soon as Erin left, Laura would be all over me.
We talked and laughed a bit more. I couldn't see it at the time, but looking back, I can see the signs of what was to come. Erin and Laura kept exchanging giggles and glances that, at the time, I barely noticed. We were all drunk and a little stoned. Who knew what they were laughing at?
As the clock moved closer to 3 a.m., the glances between them grew more frequent. Suddenly Erin stood up and said, "I have to pee," disappearing quickly into the bathroom, a bottle of wine still in her hand. Laura got a wicked grin on her face and motioned me over to her. I moved to the couch, where she slid into my lap and started kissing me. She leaned back a bit and my mouth moved down over her chin and to her throat.
"I have a surprise for you," she moaned quietly as I nibbled at her neck.
My hands slid up over her hips, pulling her closer, tasting the wine on her lips. I could feel myself getting hard already. I knew what was coming. Birthday sex was always our best. She turned to straddle me, pressing against the growing bulge in my jeans and kissing me deeply again. Her tongue poked through my lips and tangled with mine. She began grinding lightly against me and my hands moved from her hips to cup her large breasts through her shirt. She moaned as my thumbs traced the outlines of her hardening nipples.
The bathroom was just a few short steps away. We both liked that Erin could come out and catch us at any time. It wouldn't be the first time. When Erin and Laura lived together, Erin slept in the attic room of the house, which was only accessible through Laura's room. There had been several mornings where Erin had some down from her room to find us tangled up together.
Erin was the kind of person who just didn't care about things like that. She had been a stripper for a few months and was totally unashamed of her high sex drive. When she caught us having sex, she'd either laugh and clap as she blew through the room or, on a couple of occasions, she even jumped on the bed with us, over the covers. There was no play, and, though we were embarrassed the first time, we soon got used to it. And for our part, how many times had we listened to Erin fucking some guy in her room above us? More times than we could count. We had both seen Erin naked numerous times. She was just a free spirit.
The toilet flushed in the bathroom, jerking us quickly back into reality. Pulling back, Laura smiled.
"I said, I have a surprise for you ... well ... for us. Don't you want to know what it is?"
We'd been together two years, but our sex life had become more adventurous over the last year or so. Laura was finally coming out of her shell in a BIG way. I taught her how to masturbate and bought her a few toys. She loved to have me watch her use them. Even more, she loved to watch me jerk off. She would lazily play with her pussy as she watched me stroke, gasping with excitement and joy as the cum erupted from me and onto her chest or into her waiting mouth.
Her favorite thing, though, was to lie back on the bed and have me straddle her chest. She loved to have me fuck her tits, thrusting high enough so that she could take the head of my cock into her mouth each time. Later, she would pull me higher so I could use her mouth.
"Fuck my mouth hard," she would moan. "Use my mouth."
And later, with my cum still glistening on her lips, she'd smile and kiss me. "I love it when you fuck me like that ... I love feeling dirty."
As her sexual appetites grew, she wanted to try many different things. We had sex on top of a parking garage in a thunderstorm. She discovered she loved anal and would have dripping orgasms whenever we did it. She loved to strip for me and gave me fully nude lap-dances ending with a sloppy blow job. She loved to suck my cock while I was on the phone, especially if it was an important call. We had sex in parking lots, handjobs and blowjobs in movie theaters, road head, ben-wah balls and remote control vibrating panties. Not bad for a girl who grew up in a strict Baptist home.
But more recently, when I had drunkenly confessed that I wanted to try a threesome, she admitted to me that she had once made out with a girl during one of her many summers as a camp counselor in high school. It didn't get far, just some kissing, hands under shirts and panties. The other girl got scared and stopped when Laura's finger slid into her pussy. But Laura had always wanted to try it again.
The bathroom door opened, spilling light into the room. I could see Erin's silhouette.
"Ohhhhh," she said with a grin. "Am I interrupting something?"
As she stepped out into the room, I could see that she was no longer wearing her jeans. She moved slowly over to us in just a plain white v-neck t-shirt and tiny yellow underwear. She took a sip from the bottle of wine in her hand and slid onto the couch next to us. I was beginning to suspect what might be happening, but I honestly could scarcely believe it.
"Can I play, too?"
I looked at Laura. Erin was a very pretty blonde, not model material, but beautiful in her own way. Blonde, tan, small tits, with a fantastically round and firm ass. I had fantasized about fucking her many times. But, this was not my answer to give. It was totally up to Laura.
