yes!! i think he'd have some hangups about lactating--it's "not normal" for men, if he's not careful he can leak at an inconvenient time, has to keep his tits covered because expressing himself can leave bruises, and frankly his tits just HURT. ALL THE TIME. he'd prefer to get his milk from another person if possible. but if he's lactating? he may as well make the best of it.

he starts out with some recipes he finds online (and finds that it's much easier to find cookies to help aid with lactation than cookies that use breast milk--i know this one from my own googling, sigh), but as he becomes more familiar with the taste (it's not quite like cow's milk, it's lighter and sweeter iirc) and how it interacts with other ingredients, he could branch out. he might be able to run a hush-hush (because idk selling your own titty milk baked goods passes health protocols n shit) specialty business if he let people know just WHY his baked goods are even more delicious than usual.

i think he'd develop a fixation on watching people unknowingly eat things made with his milk, especially riddle (maybe even ace and deuce if you wanna get real big brother about it, and i'm also thinking about him insisting idia's skeletal ass needs fattened up some), to the point where he's a little more forceful about having people eat his food. growing boys need their nutrition!! it would likely upgrade to him becoming curious about breastfeeding directly. again, he has hangups, but i think horny brain often gets the better of him in the end.

if he does this while living in his own, he'd probably use pumps (at least sometimes) so he doesn't have to do it all by hand, but he's hesitant to order something like that to nrc.
