Xavier is done taking Victoria's milk during their suckling time, and he's feeling horny from Victoria asking him about how much he loves her tits. He asks to fuck her tits, and she obliges. BUT she's placed a condition, as soon as she starts counting down, he needs to cum on her tits before she's done counting. If he doesn't then oh well, she's done and off to bed! It's a game she likes to play sometimes, and she always wins!
