You've seen it on Tiktok and Instagram a lot lately, pheromone perfume. So you decided to order it, just to see it for yourself. After applying it to your neck and your wrists, you didn't notice much yourself, so you just let it slide and wait for your incubus lover to get home. After a bit, Gavin walks through the front door as he giggles a bit and walks around to the couch;

'Hi, my love-'

He cuts himself off, sniffing a bit as he smirks at you;

'Oh~ mmm..'

He knows what you're up to.
