Starting the main event

"Happy birthday Mark" I shout as cheerful as I can manage once the door opens.

Surprise is shown on Marks and Toms face as they see me only in Tiffany's underwear and wrapped in some gift bands with a big red ribbon covering my breasts.

Mark does not know what is going on at first but once Tiffany wispers something into his ear, his face brightened visibly and he is all smiles.

According to Tiffany's script I lean on her desk with a sexy pose and showing him the bowknot on my back.

"I am your birthday present today. Go on and "unwrap me""

Mark looks at Tiffany and asks "It is real?"

"Why are you suddenly acting shy now? I know you want to fuck her. I tried her out today. She is hot as hell." Tiffany says and pushing Mark towards me.

He hesitates first but once this hands starts to untie the knot, dropping the gift wrap and ribbon to the floor he loses all his inhibitions and starts to feel up my whole body. Especially my round butt and breasts.

"Lisa, you remember the script? As a future cheerleader you have to do it right." Tiffany reminds me.

I turn over and touch Marks cheek with my right hand as I move on Tiffany's bed. I start with some sexy poses and slowly strip the lingerie. I notice that Linda is holding a video camera recording me. I want to protest but even before I could get a word out I see Tiffany shaking her head subtly.
