several young guys hanging out or teens on a sleep over end up on the sofa watching late night skinemax each under his own blanket simultaneously jerking
can substitute tv for laptop on table in front of couch for more explicit porn 3.0 especially since taking turns gives everyone else blue balls
the lust level is extremely high sitting together on the couch watching cinemax porn. The bravest guy, usually the biggest boner, starts jerking first either balls out or under blanket. The first guy to comment is usually the next guy to start jerking. It quickly becomes a couch jerk everyone jerking -- sometimes a race starts to first orgasm.
It only becomes a gay couch jerk if one's boner if jerked by another's hand.
couch jerking avoids getting jizz on the laptop in the bathroom
