i like to think Shinji bottoms after he's had a hard day
like when he feels insecure and oversensitive about something
he keeps all his frustration pent up, until he's a mess, and jumps onto Kaworu
pushing him into bed and power bottoming
crushing his prostate on Kaworu's cock
he gets incredibly hard, like he's trying to recharge his manliness with Kaworu
Kaworu thinks this is cute and tells him how strong and brave he is afterwards when they cuddle
in the days after, Shinji is happier, but tsundere, and puts on like a "bro" act for a while
until something upsets him and he falls back on Kaworu for support
