thinking about service top will, but like domestically. it just comes so naturally to him, always watching and always catering to mack’s every wish.
whether it’s driving him around, or ordering for him because mack couldn’t be bothered to do it himself. or letting him suck his dick until it physically hurts, just because mack likes how it feels in his mouth.
mack would bat his eyelashes at him twice, and will would climb that fuckass mountain with him without a second thought.
he’d talk will into fucking in him all sorts of places, whether it was his old childhood bedroom, or the bathroom stall at whatever facility he dragged will out to train at. will would be hesitant, trying to be the responsible one, but mack would beg so prettily and will would be helpless to do anything but bend him over and clasp a hand over his mouth.
it didn’t make sense to him at first, because will had always been the one to have people fall at his feet and do as he asked. yet here he was, driving to the nearby gas station at 3 am in the middle of his summer break, all because mack wanted a slushie.
the smiths were absolutely baffled by this at first, the fact that their will, the baby of the family, was going out of his way to please his…best friend?
nah they clocked his ass immediately and have not stopped making fun of him for it, especially grace.
and mack? he loved it. he knew just how much power he held over him, and he used it to his advantage daily.
making will fuck him to another orgasm, even if they’d both already come once, even though will was sensitive. making will take his car into the car wash while he just sat in the passenger seat, and making him pay for it afterwards.
he loved how will would order for him, and stack his plates up after they’d finished eating. he knew it was greedy, to have so much and still demand more, but will always got this look in his eyes, a little glazed over and a little dumb. like he couldn’t help but listen, like mack was hypnotizing him into doing anything he asked.
mack rewarded him for it, too. he knew will’s soft spots, knew he liked it when mack let his hair fall into his eyes, and when he’d ask for five more minutes in bed in the morning.
he knew will loved it when he did stuff back, like holding his hand in public, even though mack wasn’t really a pda person. or murmuring a, ‘thank you, baby’ as he handed him something. he’ll wake will up with a blowjob sometimes, and will would always turn him around and fuck him a little harder than usual in response.
so yeah. service top will, even domestically, even platonically.
