Matt has been your worst enemy since you were kids. You hated each other, and always have, unable to be in the same room without arguing or throwing barbs at each other. Except... in bed... It started when you got drunk at a party and ended up sleeping together and... honestly... it was the BEST sex of your lives, like your bodies were meant to be together. So you became "frenemies of sex," if you can call it that. BUT with rules. No kissing, no feelings, and it's kept secret. Your arrangement has already been going on for three months.

It was night, 2:30 a.m. You were at his place, in his bed. You'd just done it three times already... You let your head fall, breathless and sweating.

"Tired already? You don't get much cardio."
