Sister's birthday

I just remembered it was my little sister, Molly's birthday today - she turned 18. I hurried back home, not so much at the thought of missing her special day, but of all her friends that would be over at our place today! Imagining being able to get between the legs of any of her hot 18 year-old friends and I'm running toward home, thinking up chat up lines.

As soon as I got in the door my Mum was standing their waiting to tell me off. "Joshua! Where have you been? Everyone is upstairs, Molly didn't want to start without you, she knows how much you want to join in today. Now I suggest you get up there immediately!"

"Yes Mum, sorry Mum." Yikes Molly must be really upset, but it's just a sleepover, why would she be waiting for me? I thought.

I got upstairs and burst into Molly's room to find her with a group of her friends - 5 girls and 3 boys all sitting in various corners of the room kissing and groping each other.

Molly looked up at me from where she was sitting in the lap of her friend Andrew, who had his hands cupping both of her tits through her top and massaging them. "Josh! Finally. You know I'd planned an orgy for my 18th since I'm the youngest of all my friends. We were about to start without you, but 2 of the guys couldn't make it tonight so girls are gonna have to share!"

With that she turned around on Andrew, opened up his pants, hitching her skirt up she slid down on his cock. Both moaned and everyone else started pulling at clothing.

"Hey Josh, I've been so looking forward to this," Gina, Molly's sexy redhead friend came over and rubbed my crotch, "Where do you want to give it to me first?"

My cock was aching to be let out now and as I stared lustfully at Gina a second pair of hands pull it out and start stroking. Looking down I saw petite Chrissie on her knees.

"Molly said share, Gina!"
