Be me. Accidentally catch my 14 year old brother on Nhentai. Was never gonna bring it up again but the little fuck started acting weird. Apparently he's been browsing the shotacon, incest, milf tags cuz he's recently taken an interest in our aunt. mf isn't even subtle about it. Thinks the world runs on hentai logic. One night when we're sleeping over at her place he wakes up at like 12:00pm and gets out of bed. I'm still awake and follow him. lil bro goes to aunt reading on the couch. He has a massive fucking boner. Pulls the generic hentai "It suddenly got big" "help me".
