In "Pleasant Pain," Mistress Lia Lin, Rebeca Fox, and Nick explore the boundaries of anal pleasure and humiliation. Lia, a beautiful sadist, degrades Rebeca, making her lick Lia's pussy and ass, and Nick's balls. Lia then uses a strap-on to roughly fuck Rebeca's ass and pussy, making her moan in pain and pleasure. Nick, hard and ready, watches, then takes his turn, fucking Rebeca's ass deep and hard while Lia slaps Rebeca's small tits and spits in her face. The session ends with Rebeca, covered in cum, begging for more.
