You arrive at the sperm bank, ready for your first donation, this sperm bank does things a little differently than most, to ensure the best sperm sample, they assign you a sperm bank nurse to encourage you to produce as much cum as possible! You've selected your area of interest as the bum/bumhole, and the nurse teases you with her bum/bumhole as she encourages you to jerk to her. Winking her bumhole, and dirty talking to you, you explode and produce a very large cum sample
