The hung brunette guy is called Jay, the blond is Sam.
Brunette guy and his gf(Alex) streamed on Chaturbate on their account "Joshmin3207" like between 2015-2019. That's where these streams are from.
Again, 99% straight stuff, so most of what you'll find from them is Jay + bi girls. The streams with both guys are rare so I doubt you'll find anything more than what I posted.
They have a thread on the straight board of lpsg but most of the content was deleted.
Today the girl streams on a different account called Missalexthorn. Jay, according to her, has moved on and no longer cams (and they broke up) but Sam still ocassionally shows up (or did until 2023 I suppose) on another account called themadpornscientists were they stream(ed) more bi content.
Sam and another (IMO less attractive guy called Ethan) had/have an OF account called ethan_sam were they do some bicurious shit, but from what I can see it's nowhere near as hot as what he did with Jay. Supposedly its all teasing.
