The brother's strong hands grip his sister's hips, pulling her onto his throbbing erection. She moans softly, her tight pussy stretching to accommodate his size.

The creaking of the closet door is the only warning they get before it swings open, revealing their shocked parents and forcing them to freeze in their compromising position.
