In a dimly lit room, a curious sister, Vídeo, decides to verify her brother's claims of purity. She requests him to undress, her eyes widening at the sight of his throbbing, uncircumcised cock. She tentatively touches it, feeling its heat and weight, before confidently stroking it to full hardness. Vídeo's own breath hitches as she sees the clear pre-cum beading at the tip, confirming her brother's virginity. Their eyes meet, a new understanding passing between them.
