I like to think the longer he restrains himself from having his way with teucer and substitutes all the other boywives of teyvat, the more his teucer fantasies skew towards violence and the more guilty he feels for having them!! starts off pretty standard... brother worshipping... collaring... tower princess style hiding from the rest of the world so tart can sink his dick into that tight lil boy wherever and whenever he wants... teucer conditioned.to want only him... starts fantasizing more and more about hurting him... he swears he doesn't really want to but he keeps having sick sweaty lewd visions of biting clean through his skin and savouring his tender, sweet flesh, cutting him to beat tart's name... guuhhhj (that's me jrowning in cum)... wants to hear him begging and whether it's for more or for tart to please stop cutting him and playing with the wounds 🫠🔥🥵
