A thanos fist is when you lick and put gushers on your knuckles like your hand is the infinity gauntlet then you proceed to fist your partner. Then, you’ll remove your fist and let the gusher ooz out the anus and eat the gushers out of the anus or on your knuckles. Finally, you get to lick the oozing candy from the anus
We got bored of regular sex so my partner and I thanos fisted and it turned into a sticky satisfying experience:)
