Fulfilling Days / ～彼女にとっての充実した日々～

Sabura is a simple dude. Lives, works and does not strain. But one day something happens that Sabura could not have expected ... A new quiet colleague, Tomoyori Hiiragi, suddenly asks Saburo for a "delicate" favor: "Could you do something indecent to me ..."
Of course, our guy was surprised, not so much by the request itself, but by the fact that a girl who was already in a relationship with his other colleague asked him ...
Although, of course, Saburu could not refuse such a tempting idea.
How far it goes depends entirely on you ...
