So like, essentially the Gabe/Rein version of that one artset where Ana pulls Rein’s hair? Gabe does it, gets the filthiest moan and is Intrigued, he doesn’t confront Rein about it initially, instead he finds out second hand that Rein is very open about his kinks, about how he loves getting dommed possibly because of how big he is, and Gabe has always wanted to dom, he’s been fascinated with it and has probably watched terrible porn when he goes to Rein to take charge.
