The pair of you sneak up behind Robert to the bathroom

You put a finger to your lip to signal for silence, and then gesture up the stairs. Lucy understands what you mean completely, and as you see Robert vanish at the top of the stairs, you lead the way as the pair of you creep quietly up the way he has just gone.

Like most student houses, the layout of this one is simple, and as you reach the top of the stairs, you turn just in time to see Robert enter the bathroom at the far end of the upstairs corridor, the door swinging shut behind him. You turn to head that way with Lucy right behind you, the pair of you leaving a wet trail of footsteps and dripping water as you make your way across the space between you and your target. Right behind you Lucy is clearly struggling to control herself and you can hear her muffled laugh as she holds her hand over her mouth to keep the volume down.

Behind the closed door you can hear Robert moving about, clearly searching through cupboards for two clean towels, afterall, it is a student house, finding clean laundry isn’t always the easiest thing to do.

“Won’t be a moment girls” Robert shouts out, the loudness of it making it clear he still thinks you are waiting downstairs, “Just trying to find some nice big towels.” You can no longer resist it, and as he finishes what he is saying, you take hold of the door handle and push it open in one shift movement.

“No need to shout Robert” you tell him as you take in his shocked face at the sight of both you of you standing in the doorway. “And no need to find me a big towel, I will make do with a nice small one” Lucy adds from behind you in her sexiest voice, and for a moment Robert simply stands staring, his mouth gapping open.
