I was already suspicious that my boyfriend was cheating on me. Then the delivery guy shows up with a package of sexy underwear clearly meant for his new slut. I tell him to wait while I look through the box, and then I decide I might as well try on one of the dresses and cuck my boyfriend with the delivery guy. He willingly goes along with it, fucking me from behind while I taunt my boyfriend. Then I keep sucking him off until he reaches a massive climax, so my cheating boyfriend gets to see my face completely covered in the delivery guy’s cum…
