You can choose any of the "Groups" in Touhou as your personal harem of obedient Boobhus, they will let you grope them, give you paizuri and receive any mating presses you desire to do anywhere at any time, who do you choose? I would pick either the Eientei, from living onahole and oppai loli Tewi, to Reisen who is built for mating presses, to Eirin's Chounyuu saggers to Kaguya's ability to milk any man dry with ease.
