My girlfriend and I had been invited to my best friend's birthday party. Everyone was incredibly excited about it. No one had seen him since he left for university. His parents had given him the house and left him to get on with it so our little group of friends arrived with alcohol and high spirits.
There was five of us all together including me and my best friend, Brad. I had been with my girlfriend, Amy, for nearly a year and since then she had broken into our little social circle. I still have no idea how I managed to catch her. She was a stunning redhead with pure white skin only broken by the occasional group of freckles spattered along her arms and cheeks. He face was the quintessence of cuteness, her eyes a deep piercing brown, full plump pink lips and a smile that would make you melt. On this night, she had her long, ginger hair down in curls over her shoulders perfectly framing the little hint of cleavage shown by her dress. Her boobs were milky white as well and she was a full 32DD. Her waist was slim then suddenly shot out with her hips for the perfect hour glass figure. Her dress struggled to control her voluptuous ass and the hint of leg she had on show was already driving me wild. We hadn't slept together yet though. She said her previous relationship had been ruined by jumping into bed too quickly and she didn't want to do the same with me. I was happy to wait for her though, and believe me, with a body that good she'd definitely been worth the wait.
The other two members of the group were both girls as well. One, Alison, was friends with Amy and joined the group because of her. She was a little shy, but friendly once you were able to get her out of her shell. She had messy brown hair just past her years but not many curves. The last friend was Sara. One of her parents was from India or somewhere similar so her skin was almost a mocha colour. She didn't have much in the way of boobs, but huge hips and ass. She was a little bit chunkier than the two other girls and her jet black hair was always in various exotic buns and ponytails.
We arrived at Brad's house a few minutes late, Amy had been messing around with her hair. I was shocked by how much he had changed. When I last saw him he was just above average height, taller than me by an inch or two, but quite weedy as well. He'd gone to uni to study computer science or something similar, so being greeted by a broader, muscular Brad took me a little aback. His hair was brown, bordering on fair, a little bit longer than most guys have it so it finished halfway down his ear. He had the hint of a beard giving him a rugged look I would never have associated with my old school friend. He looked much broader than the last time I had seen him and his arms appeared to have doubled in size.
"Amy!" He said with a smile as he drew my girlfriend in for a hug. I couldn't help but notice the way her boobs pressed up against his hard chest.
"Brad?" She almost stammered back, "Oh my god, you look amazing!" Brad had let her go and pulled me in for a manly hug.
"Ha-ha, thanks. There was a free gym on campus. I've turned into a bit of a gym rat!" He smiled broadly at us both. Amy was just staring at him with approval etched across her face. It sent a small jolt of something that felt like jealousy through me, but had a weird kick to it.
He invited us both in. The other two girls were already there having a hushed discussion and looking over at Brad every now and then. He made us both a drink and it wasn't long before the party was in full flow. Someone found some CDs and started blaring music at an insultingly loud volume and the drinks had started flowing. There was lots of chatter, lots of catching up and a little bit of dancing when a particularly good song came on. It wasn't until around midnight that, exhausted, we all ended up sat around the living area trying to catch our breath back.
"What do we do now?" Sara asked, sipping her vodka drunkenly.
"Spin the bottle?" Alison responded with a laugh. There was a groan from the other two girls.
"We're a little outnumbered Ali," Amy said with a smile.
Alison had a little think, "Well, we should do something like that anyway. Strip poker?"
"Still outnumbered," Sara said this time, rolling her eyes.
"We could do teams!" Alison shouted as if it was the best idea in the world. "Girls versus boys." I couldn't help but notice her eyes fell deliberately on Brad as she spoke.
"I don't know how to play poker..." Amy muttered reluctantly.
"Blackjack then!" Alison said.
"I don't know..." Amy mumbled, "Won't it be a bit weird?"
"Come on, we're all friends here." Brad chimed in with a wink. "You're up for it aren't you?" He continued, nudging me in the ribs. I gave a sly look over at Brad. There was no question he had a better body than me. But then I glanced over at the three girls. Amy was by far the hottest, but the other two weren't ugly either. I'd have happily seen any of them with their kit off.
"Well, ummm, I guess so..."
Amy ended up relenting. Brad went off to find a pack of cards while the girls whispered to each other and giggled, apart from Amy who was just looking wistful. Brad returned a few minutes later and, after a brief discussion of the rules, we started playing. Brad was pretty good. With the first few hands he basically single handily got the girls pants off. Amy was the only one wearing a dress, so she had to hike it up so we could see her knickers. She was wearing a black thong. I caught Brad having a crafty peek several times.
