It was only about a 15 minute walk to Sally's flat from the disco and I had my mind on only one thing. Hilary and her orgasm, that was just so cool! I had made a girl come for god's sake. I was still grinning from ear to ear when I knocked on the door of Sally's flat and she opened the door to me.
"Happy Birthday little brother of mine," Sally said giving me a big hug and a kiss.
The room was filled with music and laughter as I came in, Diane and Julie were sitting on the floor each with a glass in their hand.
"Hey look who's here at last," Sally said to the girls "It's our birthday boy looking like the cat that got the cream, I wonder what sort of present his girlfriend gave him this evening, eh bro?"
Both girls got up and came over to me to give me a hug and a kiss.
"Happy Birthday big boy," They both giggled in unison.
Judging by the three already empty wine bottles, the girls had definitely started the party without me, which I reckoned could be a good sign of the likelihood of a fun end to the evening. My only disappointment was that both Diane and Julie were wearing trousers rather than skirts so would not be flashing me any panties! Sally had a very short dress on but she was my sister and didn't really count.
"So how's the evening gone so far?" Sally asked as she proceeded to open another bottle of wine. "Wine OK for you bro?"
"Yeah, that'll be fine, although it looks like I'll have a way to go to catch you three up!"
"Tell us all about your evening so far and then we'll see about your birthday present," Sally said as she settled herself on the sofa. "You haven't stopped grinning since you arrived so I assume maybe my little brother got a nice present from your horny little girlfriend?"
"Sis! Please, for heaven's sake, what sort of a question is that?" I could feel myself colouring up and had no idea what to say.
I was sitting on the floor with my back to the sofa by now and Julie crawled over to me on her hands and knees looking me straight in the eye saying.
"Oh come on! You stroll in here, strut your stuff with that look all over your face, you must have got some tonight?"
"Hey, pack it in, this is embarrassing, I had a good time with my friends tonight, and that's all!" I said, completely unable to keep a grin off my face
"Hmm, I don't think that's all that happened tonight bro, but ok we'll leave it for now. Maybe he'll reveal all later eh girls?" she said to Julie and Diane.
They all promptly fell about laughing and chinked their wine glasses together; obviously slightly the worse for wear!
"You're looking hot tonight bro, have I seen that shirt before?" Sally asked
"No, I got it this morning, a present from Mum & Dad," I replied.
"What do you reckon girls, does my little brother look hot tonight to you?"
"Sizzling!" Diane cooed "And who helped you paint those trousers on Mike? Tights great but they must be cutting of your circulation!"
"Yeah cute butt," said Julie.
"Ok ok, what's going on here?" I asked "This is supposed to be my Birthday and I get the feeling you lot are just taking the piss!"
"Hey not at all bro," Sally said.
"Oh come, on you're all older than me how on earth would I look hot to you three?" I said.
"Hey, not that much older if you don't mind!" Diane Chuckled. Besides there's nothing wrong with a bit of cradle snatching!"
"Oh thanks, that makes me feel great," I replied.
"We'll see about that later!" said Julie casting a sly grin at Sally.
"Look seriously, what's going on here?" I asked
"Nothing! Really, nothing at all!" Sally said. "Now let's get the party started" She got up and put an LP on the record player and Julie & Diane joined her in the middle of the room and started to dance.
"Drink up Mikey, and lighten up it's your birthday for heaven's sake!" Said Sally.
I drank a couple of glasses of wine and watched the girls enjoying themselves as they danced to one song after another, then as a slower song started Diane came over and grabbed me.
"Me first for the slow dance," she giggled draping her arms around me while we smooched to the music.
I only had my hands on Diane's hips when she pulled me in closer "Come on Mike put a little effort into it!"
Now Diane is tall girl and with her heels on stands about and 2 inches taller than me, and it has to be said, she was a woman with a curve wherever one was needed. I had always thought she had a magnificent figure, and I remain to this day an advocate of the more curvaceous woman. Diane's ample boobs were pressing into my chest, and with her hips swaying, her pussy was rubbing my crotch. This was a recipe for disaster for me and my rampant hormones!
I was getting a huge boner and tried to position myself so that Diane wouldn't notice, god how embarrassing would that be? Diane however, had other ideas as her hands went to my butt and pulled me in closer to her as she continued to grind her pelvis into me, she also took my hand and placed it on her bum.
Now don't get me wrong, this was nice and I was enjoying myself, but I was also really unsure about what was going on, I looked over to the other two to see if I was going to be rescued, only to get another shock, Sally & Julie were in a clinch that raised a few questions in my mind. Julie was by far the smallest of the 3 girls, no more than 5'1" tall, however she was beautifully proportioned for her size, with a gorgeous bubble butt and largish boobs, a real little pocket rocket!
Julie was resting her head on Sally's chest with both her hands resting on her bum, "Wow that looks so hot," I thought to myself but this was all seeming a little surreal to me, my sister and her friend were lezzing it up. Me I had one of Sally's closest friends in my arms, grinding her pussy into me, "Ah well go with the flow," I thought.
The smoochy music came to an end at which point Diane broke away from me. "He's definitely growing into a man Sally," Diane said placing the emphasis on growing as she said it.
I sat down fairly quickly in order to try and hide the bulge in my trousers, although I'm not sure I was kidding anyone!
"Really," Julie said "And what part of him has grown Diane?" She laughed as she sat down next to me and put her hand on my knee.
"Oh just the most important part," Giggled Diane
"Hey leave the poor boy alone you two," Sally said, winking at the pair of them. "Mike make yourself useful and open another bottle of wine will you? The ladies and I need to get your birthday present ready, come on girls, time to get ready you come with me," Sally called as she set off toward her bedroom.
