Mitsuki only has a moment to prepare before he's being lifted, instinctively tightening his legs around Akihiro. He huffs a little but it's got very little to do with offense and a lot to do with hiding how hot it is to be manhandled like this. He's a grown man, he can absolutely walk to the bedroom, but if this is the alternative then why would he?

He tilts his head to offer Akihiro as much access as he wants, threading the fingers of one hand deeper into his hair as encouragement because it feels very, very nice. His other hand slips forward to start fiddling with the button at Akihiro's throat. Akihiro is overdressed and that simply won't do.
