Of course not, you cum

You cant hold it back. The sight of your hot roommate, your previous masturbation, and her eyes still fixated on your cock were too much, and you shoot shot for shot against the glass wall of the shower standing between the both of you.

"I'm sorry," Emily shouts, looks at you for a second longer, and then quickly closes the door.

You moaned frustrated.
Not only die Emily catch you in the shower while you masturbated, you even came right in front of your eyes in an half-ruined orgasm. You dont even want to imagine what she must be thinking right now.

Nevertheless, as soon as the door closed, you grab your dick again and quickly jerked off again to at least get some satisfaction out of the situation. Then you continue your shower.
