A couple. A rather randy couple

You spot a guy and his girlfriend. The guy's a little bland, hunky, tall, with a big namby pamby smile locked onto his features like a big dumb puppy. The girl's a looker and all, but that isn't what caught your attention. It's the overall vibe from these two apes.

They're clearly a tad drunk. You feel they're a little older than you, so perhaps they're both studying for some horrible Master's degree in some impossibly hard and prestigious domain like, I dunno, Engineering, and are taking out their stressed, burned-out sorrows in the cafés and in, (cough!), companionship. They're also extremely touchy-feely. They look like a very recent coupling. And you just heard something from the girl to the effect of "enough drink, let's go home". You figure they're probably going to screw each other's tits off. This is going to be fun.

You fall back as they pass you in the opposite direction, then turn and follow them. They take you a damn long way across the city, leading you to take down a peg the level of inebriation you initiall thought them to be. Assuming they had common sense, even a young, healthy couple wouldn't wonder through the dark dank streets at night if they were ostensibly tipsy. They must be having a good time. Whence your impression that they must have only recently got together. Of course they may have nailed you from the start and are trying to get you to back off. After all, at this point, in the empty alleys, you're the only other person in the same streets as them. Better be more discreet next time. Somehow.

It turns out they were actually going home, as they finally stop in front of a huge blue double-door set into an shallow alcove, and the girl begins fiddling with the lock. You freeze time.

Now how do you get in there with them, without them knowing? You keep walking until you reach them, then stop to think. You look back to where you were a few seconds ago before the freeze. Fortuitously, your stalking distance put you just far enough that your form would have been swallowed up by the shadows of the empty alley. The lampposts throughout most of the town have switched off for the night by now. The only source of photons anywhere now is the full Moon. So you don't have to worry about the couple noticing that you completely disappeared from where you were while following, if they noticed you in the first place.

Now you have to hide from them just long enough for the double-doors to be opened. Specifically, for them to be opened just enough that you can slip through without having to affect the couple. Without having to interact with them. In broad daylight this might be quite impossible. Right now though, there are shadows everywhere. You move along past the couple just a couple of meters to another double-door in a similar alcove. You stand with your back against it, and are envelopped by the blackness. You mentally snap your fingers.

In the midst of a giggle, the girl gets through the lock and opens the door. You hear a loud creaking sound and shuffling footsteps as the two move to walk in. You freeze time yet again, and emerge back on the scene. The door is open, but the girl has already started to go through. The guy is well out of the way, so you only have her to deal with. As you slither around and past her into the building, you realize you need to hide yet again, this time until the couple have led you to their flat. What a potential nightmare!

Once inside, you fumble around for a light. You already have some idea of where you are: it's cold and draughty, most likely the bottom end of a large stone stairwell. Sure enough when you find the light this is exactly what you see, and before long (although that really doesn't matter, you have all the time you might need) you hatch a plan. You climb the stairs to the first door, presumably leading to a flat, counting the stairs along the way. You repeat this all the way up to the top of the building, and do the same on the way down just to make sure. Upon arrival at the bottom, you look around for a hiding place. Behind and underneath the first twenty or so steps. That will do. You turn out the lights and just rethink your plan to make sure it's sound. From here, you'll unfreeze time, allow the couple to find their flat, counting the number of steps they take, and when they stop, freeze time and go up to join them. Striclty speaking you don't really need to count their steps, because it'll be pretty obvious that they've arrived when they do stop, but this way means you'll know how close they are to any of the doors and will be able to anticipate. You won't be caught by surprise. In any case you can afford to be obsesively cautious like this. You unfreeze time.

Damnit. It sounds like they're off all the way to the top floor. You freeze them again and rise out from behind the stairs and up a few floors. Upon setting things in motion again the first thing you hear (beside the varous noises made by the couple) is the sound of a lock clicking, followed by the plaintiff squeal of long untended hinges as a door opens. You freeze all again and climb the rest of the way up. Again, you have to slide past the couple who are halfway through the opening. This time it's a lot trickier because the silly sods are locked in a kiss, while going through. After trying and failing to get by on two legs, you opt to simply crawl under them on your hands and knees.

Good. You're inside. You have breached the fortress. Now to find yet another corner to hide. Preferably in the bedroom where the pumpy de rumpy may be set to happen. You find said room, and a decent hiding place in the form of a huge, very sturdy cupboard full of space and clothes. You climb inside, hold the door open just a peak, restart time, and wait. Within seconds the bedroom door opens and in come your lab rats. You hear clothes sliding off their bodies and being thrown here and there. A small lamp comes on and suddenly you can see them on the bed, half naked and writhing against each other in the beginning throes of passion. The shedding of fabric reveals a large, muscular man with strategically developped muscles, suggesting a physique of visual rather than practical value, and a shapely woman of large breasts, wide hips, and very red hair. It isn't long before the D goes in.

Now. What. Shall. We. Do? MUAHAHAHAHAHA!

You let them thrust for a little. Get used to the sensations they must be experiencing. And then you decide it's time to strike. You freeze them in the act. You come out of the cupboard. You assess the situation. The guy has his shlong deeply buried in his girlfriend's intimate folds. You roll up your sleeves, get right up close, reach around the dude's hips, and HEAVE. Out of breath, you take a good ten mintues to slow your diaphragm and your heart, before observing the effect of your action. Success! Where there was penetration there is now a long bent thing with a sort of lump on the end, suspiciously hanging around on the outside of the orifice it evolved to lodge itself in. Satisfied, you return to the cupboard, and restart the action.

This is only the first time you've done this to them, and so you expect little reaction. Pulling out a little too far surely occurs even under normal circumstances, and in the heat of the moment you doubt the guy is going to be too bothered by the contradictory information from his senses. You just hope he doesn't retain the sensation of you pulling him back. Sure enough, nothing much happens. Coitus resumes as normal.

Not so the second time. Well not quite. There's a brief interruption. The guy stops thrusting and looks down between his legs at his yet again misplaced man-rod. He puts it back in and goes at it again. His ladyfriend is a little quieter after that.

The third time she pushes him off her and they stare at each other. You know they both know something's not right. That's heartening at least. She's not immediately blaming him. It must be a good relationship.

They both know the dick was in, damn deep, and then it was out. They both know it suddenly was out without there being any backward movement from the guy.

"Babe, I feel like I'm being pulled out from behind, but when I look down it's like I'm right in you just on the outside, like, my dickhead ends up a little under your belly-button. It's uncanny."

"I feel it too. One minute I'm swallowing you up down there, the next yer fuckin' flappin' around on me tummy. Maybe we drank some weird shit and our brains are fucked?"

They're a little unsure what to do, but decide to try and finish and call it a night. After you let them go at it for a while without intervention, they start getting properly back in the mood and eventually start trying out different positions. For a time you simply enjoy the view, but eventually get bored, because how could you not? Real life sex in front of you happening in real time! Who wouldn't get bored? You're not sure whether to push them further into despair or just go home.
