Yui's butt is sensitive, perhaps too sensitive for an actual penis to penetrate her. Would need months of dedicated training with fingers, toys and tons of lube before she's ready for the real deal. But when it does arrive, however, she's be cumming buckets.
Ritsu is not a fan but will let you have fun with her butthole if you're persistent. Won't enjoy it too much.
Mugi, curious as she is, will suggest trying anal herself, and there's a 50/50 chance she'll either like it or won't comment on the experience at all like it never happened
Azusa will be shy at first, but will quickly become a dedicated buttslut
Sawa-chan is only interested in anal because she wishes to giver her vaginal virginity to a special someone
