That's basically claiming hes milking males; if grabbing a human womans breasts counts for lewd, then why in the world would grabbing humanoid breasts not count. It should be a self satisfying contract condition.
the payment is lewd offerings to MC
he does not view milking as lewd, it is a job he loves and does passionately
Would you get hard from milking a cow? Actually I'd rather you not answer that.
The point is, milking isnt sexual by nature.
Love how the Harpy was instantly okay with him milking her.
Like, the second he touched her, she just shyly hid her face behind her wing and let him go for it.
