Fast forward makes me horny.
When i was on my first command, my roommate used to rent porn tapes by the back-pack full. He'd copy them for the submarine patrols, loaning them out to anyone that was interested.
But while he ran the tapes on two decks to copy them, he'd use a third tape to watch something. And he had no patience for conversations, setting, stripping, lubricating or anything but the actual bumping of uglies. So he'd fast forward. Any time i was in the barracks, no matter what i was doing, from about 1400 to midnight, there were people in the back ground groping each other at 4x speed.
They enter the room, bump faces, appear sneeze their clothing off, jump into bed and suddenly there's these closeups of dangling boobies and penetration. Halfway through the cum shot, we're back on 4x, so the sperm shoots out like a staple gun, and there's more jerky movement until someone else is sticking it where the studio lights shine.
I never noticed until just recently. My kids are slowly working their way through our DVD collections, stopping now and again for dinner, chores, weapons drill and to taunt the missionaries on the sidewalk. So while i'm surfing the net, they load a disc, get near the scene they stopped watching at, and fast forward to where they left off.
And while the characters jerk their way across the space station, the back of my head is suddenly expecting Delenn to sneeze her clothes off and bump her face against Sheridan.
