Something tells me that the guildmates won'T have much sexual conent it is just going to be bonus scene or two.
There's enough shown from the previews to show this isn't quite the case.
Scenes I'd guess every guildmate has.
Hang Out with Skin in the bedrooms (based on bathing Yui and the Kasumi mirror image where you can see her ass and panties in the reflection)
They lewd you (Pic of Kasumi which seems to be her reaching to your dick)
You Lewd them (Inusuku's history, this is almost a given. Whether fingering or licking could be different per girl)
Bedroom Sex (Pic of Kasumi pretty sure taking dick)
Beach lewd (We were shown a menu where you can pick each guildmate by name, and a scene of yui / kana at the beach
Beach Sex (Inusuku usually doesn't go all in on a menu like this for only sex, otherwise its a missed opportunity)
Hot Springs Sex (Just a missed opportunity if they don't considering the choices the hotsprings have already)
