Your sister's friend walks in on you pleasuring yourself, your hard cock pulsing in your hand. Instead of turning away, she watches, her breath hitching as you stroke your length. Emboldened by her gaze, you continue, your moans filling the room. She can't resist, moving closer to taste you, to feel you. She takes you in, her mouth stretching to accommodate your size. You warn her, your body tensing, but she doesn't stop. You cum, hard, filling her mouth, your body convulsing with each spurt. She swallows, licks her lips, and smiles, leaving you shaken and thrilled.
