Derek likes to surprise the Sheriff with new stuff he got from the internet. He has the whole day to lounge around and care for himself, after all. Making sure his nails are short and clean (he tends to scratch when he’s allowed to lie on his back while he’s getting fucked); trimming his beard until the line across his cheeks is nice and sharp; working out and showering for hours, making sure his pubes are nice and clean – aaannnnd surfing the net like a lazy weirdo with the laptop on his belly and one hand down his pants, even though he’s not allowed to come. (he just likes holding a cock tbh.)
On there he finds the best things he knows will drive his daddy wild. Like the time he stood in the hallway in nothing but a pink jock strap when the Sheriff came home. John very much appreciated the ‘baby boy’ printed on the broad elastic band, as well as the way it looked so bright and young against Derek’s dark, hairy body.
He ate him out right there, pressing Derek against the wall and nosing into the hairy crack until Derek had to stand on his tip toes, groaning into his stacked arms at the enthusiastic, deep licking he received; big cock straining against the confines of his jock strap, knowing full well he’d not be allowed to come any time soon.
