My girlfriend and I worked together to service the single man, all to lick his penis until it was fully erect, so that my girlfriend's cunt would be filled even more completely. Our tongues would occasionally intertwine on his penis, and watching my girlfriend so absorbed in sucking and spitting out another man's cock, I couldn't help but masturbate while simultaneously stimulating her already overflowing cunt. Seeing my girlfriend trembling as she sucked the single man's balls and penis, I also leaned in and licked his large glans.
