Discovering choking [MF]

Wrote this for a ARAD, l on discovering taboos, reposting here!
My SO and I are pretty kinky. Gagging, anal and cum play happen weekly and we occasionally fucking other guys and girls, that kind of thing. But I’d never choked her.

To set the scene, she’s 5’3 and runs/ lifts 5 times a week, ~50kg kinda athletic. I’m ~80kg, ex PT in the best shape I’ve been in since competitive fighting. Both professionals in our mid twenties.

Lately we’ve got into watching Archer. At one point whilst Carol, with a voice oozing sexual desire, is describing her fantasy of being choked it happens. My cock starts to fill out the inside my trousers. Before the scene ends there is a thick outline in my crotch.
I straight out tell my SO I think Carol is crazy hot, she loves me getting off and this impromptu boner lights up her eyes.
