Most commonly found in Parkour porn. When one partner backflips and lands with their penis inside of the others butt, mouth, or vagina.
My friend got caught watching Parkour Porn by his dad and they both watched the backflip insertion portion.

An observer and/or participant in an intercourse session --- often the "second" guy/girl in a threesome --- who is tasked with promptly tucking the dude's randomly-swaying woodie back into the chick's love-tunnel whenever it accidentally pops out from his having unintentionally withdrawn it a bit too far prior to his next thrust; this relieves the lovers from irritating pauses in their steamy copulating to semi-blindly fumble back there themselves and re-insert the errant schlong each time.
Finding a willing re-insertion assistant is usually quite easy --- often, you simply need to approach a random passerby and offer him/her a "standard" reward for his/her help: agree to allow the person "a turn of his/her own" with the opposite-gender intercourse-partner afterwards (or at least a post-session hand-job/blowjob from the gal if it's a male assistant), let the person play with the balls and butt-cheeks of the copulating duo for a few moments after each occasion during the "hot 'n' heavy" when his services are required, and/or maybe allow him to give one or both partners a full-body massage --- extra points if you both also give him a nice soothing rub-down in return, of course --- after the session is over.
