Ok guys, I know these aren't technically 'briefs' but they are bikinis which I believe are just as hot depending on the man they are on.
Please start at the 1:00 mark with Lex laying ass up on the bed as the female enters. Also, unlike most scenes where we get just a brief glimpse of the bulge, these two continue on their foreplay for a few minutes allowing us far more than usually expected in hetero porn. The bikinis don't come off until 4:37!
I'm sorry if they aren't technically briefs but this video just needed to be here(I thought, anyways)
