Use the dildo

Fuck, you're so horny from just the thought, you just have to do something! The giant green horse cock dildo feels hefty in your palms. There's no way that could get inside you! Not without lubrication at least, but luckily there's a bottle of the stuff in the locker. You cover the dildo with a generous helping; this thing is more slippery than a wrestling nudist covered in olive oil! It comically shoots from your hand, and you juggle it in the air frantically to catch it.

When you're done playing around you start to "play" proper, rubbing it between your panty clad buttcheeks, your ass in the air and one knee resting on the locker room bench. The flat tip of the dildo slips under the elastic, pushing against your pucker like a square block trying to get into a round hole. But your hole gives in, slowly letting it stretch you wide, centimetre by centimetre, inch by inch. God it feels good to be filled like this, to feel your hole violated like this by a rubber monstrosity! You only wish it were real, that you were pinned down and used as a giant cock sleeve... Aah! You squeal as you shift your body to more easily thrust it in, your back on the bench, your legs in the air and your ass cheeks further apart than they were before, allowing you to insert more. You manage a foot, the other foot of rubber dangling over the side, and no matter how hard you try you can't take more. But what you have is good enough. You keep a hand wrapped around the dildo, frantically trying to shove it back and forth in your gaping hole, as your other strokes your cock with the same gusto...-

...

...okay, you definitely heard something this time, but your current predicament makes it hard to care. You manage to stand up, the dildo kept in place by a tight sphincter, and while you try to remain quiet your hands are still at work pleasuring you, a squelching and fapping sound echoing through the changing room.

Then something sprays against your ass. It's wet and gooey in your hand, but amazingly when you take a look at it it's not there! You can feel it dripping between your fingers, but you can't see it!

"Fuuuuuck... Holeeeeeee..."

The male gutteral voice came from behind you, but as you turn around to face the threat you see nothing! But clearly there is something, as a moment later you're reeling from a punch to the face. There's only one thing you can deduce from this. Whoever this is they're invisible!

Before you can defend yourself the assailant grabs one of your legs and lifts it sharply, causing you to lose balance and hit the floor hard. As you're recovering, the attacker flips you over roughly, and with sharp tugs yanks the bra off your chest, closely followed by your panties. You feel something poke against your backside, something thick and long and slick, no doubt a cock, but the dildo blocks the passage.

Oh god he's going to pull that dildo out of you isint he?
