After being fucked and whored out by her cruel Stepmother, sissy Molly is now at the mercy of her even more wicked and teasing Stepsister Krissy. She doesn’t just whore Molly out but decides to sell her. An interested customer comes by, pays for sissy and will be taking her home the next day. Since this is their last night together, Molly’s Stepsister teases and edges the sissy inside her chastity cage. Sissy Molly is so horny that even the vibrator pushed against the confines of the metal cock cage is driving her crazy. But Krissy knows how to keep her slut toy on the edge, and pulls away the vibrator each time sissy gets close. Leaving Molly to hump the air, desperately trying to achieve some sort of relief. Finally, Stepsister Mistress Krissy milks sissy inside the cage. But it’s a ruined, agonizingly frustrating orgasm that just drips and flows desperately inside the cage. Then, Molly is fed the cum, made to lick it all up. Tomorrow she will be sold and taken. This is probably the last orgasm she will experience for a very, very long time.
