she could also be using her mouth and holesI mean technically if you have two guys standing across from another two guys and the girl grabs the touching penis tips, she can jerk off 4 guys simultaneously. It's called middle-out and is based on the "D2F" or "dick-2-floor" calculation being the same for each guy pairing. Once a guy nuts, on the outwards thrust he's swapped in for another guy so she's not wasting arm motions, this is truly how she can maximize profits
