A chance encounter with her 18-year-old ex-girlfriend reveals a shocking new kink. As they catch up, the young, hungry ex can't keep her eyes off her former lover's crotch, licking her lips in anticipation. She suggests a game, a bet, to make things interesting. If she loses, she'll take a hard spanking, but if she wins, she gets to lick her ex's balls until they're clean. The tension builds as they play, and soon enough, the ex is bent over, her ass reddening under her ex's firm hand.
