Usually the easiest choice is to pick the biggest, but I didn't expect my most favorite girl to turn out to be the biggest (Angie), though Mikan, Hiyoko and Himiko are always welcome to use me too
If we're going by purely the cock, then Chiaki. Looks like the perfect size for a mouth and an untrained asshole.
I have a thing for dick piercings so Ibuki is it for me~ plus sometimes it can be hard to enjoy a huge cock if they don't know what they're doing with it >w<
Akane Owari for me
