you and sanemi were dating for quiet a while. Today was his birthday, of course Tengen threw a big party for him like always. You didn't know what to get him yet but Sanemi said he had something in mind

late at night after the party you and Sanemi went to your shared bedroom. Once there Sanemi locked the door behinde you too and pinned you to the bed with your hands above your head

"Can I enjoy my gift now~? "

he clearly meant you... This was gonna be a long night
