It is what turns best friends into enemies... or into brothers-in-law. Unfortunately, it's never possible to tell which one it shall be. Always a terrible gamble, the age-old question: To fuck or not to fuck your best friend's hot sister? What shall be the answer? Hopefully the former... otherwise, this story would be rather dull.

Derek had good reasons not to tell his friends that he had a younger sister. Most of these reasons concerned her profession. If any of his peers found out who she was, they surely wouldn't stop negging him about her. Or snatch his phone to get her number, one way or another. They all knew that he had a younger sibling, of course, there was no reason to hide that... he just made sure not to follow her on Instagram or any other social media. It wasn't like her images weren't constantly on his feed anyway. Not much of a surprise, given her however-many-million followers. Surely, most of his friends had seen photos of her before, Derek knew some followed her account. Fortunately, their last name was common enough. So far, none had figured out that they knew the older brother of one of every runway's finest.

These circumstances were the reason Derek wasn't quite... exhilarated when Alexandra asked whether she could crash at his New York pad for a few days. His cozy apartment was right between some of the venues she was booked for - Fashion Week was coming up, and Alex was to run for most of the greats. Seeing his sister again would have been great, of course. He was 26, she had turned 21 just some weeks ago. The perfect opportunity to go barhopping with her before her schedule ramped up. On the other hand... every moment he spent around her meant that one of his friends might spot her. Hell, maybe she'd even take a selfie with him and post it! Derek would surely never live that down.

No, that couldn't happen... but Derek's girlfriend Abby had the perfect solution: A vacation! Alexandra could take over the apartment for a whole week, and none of his friends would find out about it. Derek was sold, and Alexandra was happy she got her brother's fancy place all to herself. A message in the group chat warned his friends he wouldn't be around for some time.

...

Except that one of them didn't quite... remember that two days later. It was time for their weekly 420 session, after all. Somehow, "vacation" and "vacant apartment" didn't quite find a union in the friend's head. This certainly sets him up for a surprise when a scorching hot topmodel opens the door, rather than his best buddy. And what do you get when you take a deliciously handsome stoner and match them with a confident woman who could really use a way to vent in between fashion shows? You get great sex, that's what you get.

That's the prompt. Don't jump right in - tell me something about the kind of story you want to explore here, which kinks would be important to you for that and why those kinks interest you. I like catering to my partner's interest, so if you are detailed about why and how certain kinks and themes excite you, we will have a lot more fun together. I value effort a lot, so take your time! I have some ideas for the looks of our characters too but I'd love to see/read your ideas too! This is obviously a prompt about models, so... no singers or actresses :)

I am 18 and all participants and characters must be 18
