The lad's gaze is glued to the two sisters, their bodies intertwined in a dance of lust. He watches as one sister takes the other's hard cock in her mouth, her lips stretching around the thick shaft. The other sister moans in pleasure, her fingers playing with her clit as she rides her sister's face. The lad's hand reaches into his pants, stroking his own hard cock in time with the sisters' movements. He's never seen anything like this, and the taboo nature of it all only serves to heighten his arousal.
