In this world, Doms go through rut cycles. You're at your best friend's for a beer and games when he begins acting odd.

Jim had invited you, his best friend of many years over for a video game night. The two of you have been having sleepovers since you were little and continued the tradition into adulthood. You noticed today as he let you in, he looked a little flushed. As a Sub, you were always on alert of this around your Dom friends, "Jim... Do we need to reschedule?" You asked. 

Jim clapped you on the back, his demeanor was as friendly as ever, even if he was giving off a strong, unusual scent, "Nonsense! We did all this planning! I get your ass off work and in my house. We'll be fine. Okay?" He assured, though... He knew what he was feeling. He could already feel his shorts getting tighter from your Sub scent.
