Synopsis
Mom rented a place away from home to accompany her son for exam prep. Dad came home late at night, unable to bear the loneliness, and pinned her to the bed, having her ride him; her wet pussy sat all the way down, juices splashing everywhere. The son pushed the door open and caught them, then hid outside the door to peek, his cock so hard it hurt. That night he lay on the bed in the next room masturbating in secret, recalling how Mom rode Dad and moaned wildly, stroking himself while panting softly, cumming all over his hand.
