Thinking about Saint Bernard!price who is too damn old to deal with all the energy border collie!reader has at night...
He loves you, he really does, but price also loves not having knee pain every single day of the week and having to chug coffee in the mornings. Without fail, every night you're crawling on top of him, nosing at his neck with a playfully twitching tail.
"Settle down, runt. I've got meetings in the morning tomorrow, and you have training." He huffs, but indulegently let's you snuffle at his jaw. Sometimes, you rut against his thigh for a bit before tuckering yourself out.
Tonight, clearly, is not one of those night.
You yelp in surprise when price flips your positions, looming over you with a fondly annoyed expression. "You," he huffs, scoffing when his hands find an already lubed hole "are a menace. What happened to my obedient mate?"
You simply whine, ears pinning in apology and thighs falling open. As if price would ever believe your faux-guilt when your tail is thumping against the mattress as he lines himself up.
In one swift, overwhelming motion, price thrusts down to the hilt. This time you do yip in shock, back arching, ears perked. Before you can properly bask in the moment, price is putting his full weight on top of you with a gruff "i don't reward bad behavior, you know that, runt."
One, two, three half-thrusts and price's knot is inflating. Keeping you two locked together, he hunkers down and ignores your pitiful whines. The rest of the night you're pinned under price, even as he goes soft and his cum leaks around you, he's dead weight when asleep.
You fall alseep too, eventually, edged and horny the entire night. Your mate just laughs at your grumpy expression in the morning, licking your neck soothingly and reminding "it's not the weekend. Yer well aware of the rules."
