Sissy ending...

After you finished trying everything on, Kay was nice enough to pay for the ones you liked! She said her boyfriend had it covered! You found yourself wearing the panties you'd gotten that day more and more until you just threw away your old underwear, content with never going back. Kay gave you her number amd you would occasionally go and hang out with her and her boyfriend... He was a rather quiet guy, hard to describe, and you don't recall ever catching his name... Kind of weird but eh... Who can judge... He would usually be cleaning or cooking when you'd come over, dressed fully in lingerie and you notice that Kay would poke fun at him for it, but it was obvious she cared deeply about him still... You feel determined to find something like what they have, a respecting, caring woman who understands your wants and is willing to love you despite your tastenin apparel... Luckily, Kay introduces you to one of her friends and the two of you hit it off immediately... Over the months, you notice that she never gets naked in front of you and that her and Kay spend a lot of time alone together in her bedroom while you and Kay's boyfriend clean her apartment, but it doesn't bother you any... It doesn't even bother you when your new girlfrie... Nevermind, mistress, is what she wants you to call her, locks your little cock up in a chastity cage...

One day, you come home from work to find a strange guy walking out of your bedroom, his large cock hanging out freely as he smirks at you, and you don't even mind... You just sit down on the couch and listen as he goes back in and fucks your girl into bliss...

But you? You're already living in bliss...
