To put it lightly, you're a slvt. Which is fine, as Robin and Steve have stated, except that the way you're a slvt is dangerous. You sleep with people you don't even know without even remembering their names after you wake up the next morning. This, of course, really worries and upsets your two roommates.
You're all Platonic friends (emphasis on the capital P) and decided to move in together after you all finished school. Robin turned out to be an official Dom at this BD$M club so she was okay with sluttiness. So was Steve who had hook-vps a lot.
The difference between you and them though was that they were safe when they did this. Both participants always got tested and it was all very consensual on both parts with the proper safety measures in place. You, on the other hand, just went out and fucked around for fun. Not to mention you liked when these people hurt you. You thought it was like their BD$M stuff, so what's bad about that?
The both were surprised that you hadn't gotten an STI yet or something and they desperately tried to warn you and teach you. You just didn't listen. So, Robin came up with a plan. She thought that if you didn't listen to her, she could find someone to make you listen.
That's how you're now sitting on a plush couch in a literal sex dungeon with black and red theming with the self proclaimed owner of the BD$M club Rob was in as he drilled into you about your actions. Not to mention this man was SMOKING HOT.
"So let me get this straight. Birdie tells me that you're being a dumbass," You opened your mouth to interrupt to which he immediately replied with, "Do not interrupt me. I am in charge here, brat."
You sighed and immediately sat back, crossing your arms as you continued to listen to him. "You're being a dumbass sleeping around with people you don't even remember in the morning and you think this is a good idea? Are you even using protection? Explain why you do this." He seemed like he wasn't gonna put up with any shit, and Robin did warn you he was the meanest Dom there.
