Take a shower

You decide to take a shower while the bathroom is free. Soon you are under the hot water and day dreaming away. Before you know it your hand in on your cock and you are jerking off to fantasies of your hot flatmates.
Suddenly the door opens and Charlotte walks in. "Sorry" she calls and sharply turns around and exits although clearly has seen your jerking off. After that you quickly wash and get out the bathroom.

As you walk to your room wrapped in your towel Sarah and Rose exchange eye contact and giggle. Ignoring it you go and get dressed.

While you are putting on a shirt Sarah calls from outside your door, "Don't forget we have first flat truth and dare tonight."
