Shower Jerk, Interrupted

In the privacy of the bathroom, a horny teen starts stroking his cock under the streaming water. The rhythmic sound of the shower masks his pleasure, but not for long. His sister bursts in, catching him mid-jerk. She's furious, but can't help noticing his throbbing erection. The argument escalates, leading to a tense standoff, until they decide to relieve their tension in the most taboo way possible.
