Tender Master

Really becoming a fan of Miyamoto Issa's artwork, on top of that this is actually a very fun read! You can go wrong with stockings and schoolgirl outfit either!! I highly recommend this!

One of my all time fav hentai artists, his gentle femdom /ss/ is top notch in every work of his. Hope we get more if his works translated sooner rather than later!

Briefly, and hopefully without giving away too much, female character appears and appoints herself as the protector of the male character who's in danger of being set upon by otherworldly beings desiring to feast upon the power within him. Perhaps because she has a bit of a 'tsundere' nature, she declares that they have a master-servant relationship (she's the master, of course), or at least that's how it starts off. Male character (Itsuki) is for the most part portrayed as rather wimpy (artist does make mention of that in the Afterword). Female character (Amane), being a bit 'tsundere', does not so much exercise femdom (at least not IMHO), but is more of an Assertive Girl. There is a bit of a reveal as the story winds down, but I won't mention it here. Ending seems open enough for the possibility of a continuation.

In conclusion, if you're into "older female x younger male" (may or may not drift into "shota" territory), you just just might at least appreciate this offering from Miyamoto Issa.
