You've been out with Dahlia a couple of times and have finally made it to her bedroom. She's horny and ready to suck your cock, but when she unbuttons your pants she starts laughing and mocking your small cock. She's still horny and decides to lock you into a tiny chastity cage, then puts a strap-on on you. She sucks and rides the strap, taunting you all the while, and cums. Once she's done with you she sends you out the door, still in your chastity, telling you that she's your keyholder now and that she'll call you when she's ready for more fun.
