Chicken out

Sam is about to say something, but finds the words are unable to leave his mouth. He curses himself silently as his eyes fall to Shelly's cleavage again, able to make out the outlines of her nipples through the dress.

He doesn't get chance to say anything else as the van suddenly lurches, heading underway and pushing his body firmly against Shelly sat beside him.

Shelly's hand lands on his thigh, steadying herself against the shaky drive and Sam becomes highly aware that her finger tips are almost brushing his cock.

Shelly quickly removes her hand, looking flustered herself and she pauses for a moment, looking first at the naked Emma and then at Sam. "Oh... right.... I was supposed to join you." She finally says.

Sam watches in awe as Shelly slides the straps of her dress off her shoulders and then down, completely revealing her bared magnificent breasts to him. She lifts her arse off the seat, brushing her skin against his as she slide the dress all the way down dropping it at his feet, before sitting back down in nothing but a tiny black thong.

Sam swallows, trying to turn his attention to the road, but at every turn feels his body pressed up against Shelly's, and begins to wonder if perhaps she'll take off the thong as well.
