Arriving home unexpectedly, I found Amber, my ex-girlfriend, in our bed, her lithe body writhing in pleasure. She was riding a large, black suction cup dildo, her twin-like sisterly features contorted in ecstasy. Her moans filled the room as she bounced on the toy, her wetness coating it, her perky breasts bouncing in rhythm. Caught in the act, she froze, then quickly tried to cover up, but the sight of her, panting and embarrassed, only served to arouse me.
