JOCKS WEAR JOCKS! (jock straps)

I like how the bottom looks surprised to have a rear entry when his jock keeps his backdoor open for easy access.
yeh, cock and balls sacked in the pouch and straps framing his butt cheeks and as you say, back door open, perfect way to fuck - and be fucked - but @d look happy not surprised to have a length sliding up my rear entry
