Damn, this thing is huge! Nothing humanb could use a condom this big. You decide against trying it on, but maybe you can play with it. A silly thought crosses your juvenile mind - you could wear this down to dinner and see if anyone guessed what it was. Lifting it up, you try pulling it over the top of your head like a stocking cap. It's a little tight, but slips down over your hair down to your ears, aided by the slick lube.
Looking in the mirror, you giggle. It really does look like some sort of weird hat. Except it is sagging down over your ears now. Then you blink. A definate ridge is pushing out around your whole head under the latex. Lube runs down the sides of your head and trickles down your, oozing from the sagging bottom. The lube leaves a dark trail, apparently staining your skin black.
As you stare, the 'hat' starts to take on a peculiar shape. It looks like you are wearing a black chef's hat, sort of. The condom sags suddning and drops over your ears, the front sliding down just above your eyes. You suddenly realize the 'hat' on your heat is looking like the end of a horse's cock, complete with flare.
You gasp and try to pull the condom off, but your fingers melt away as soon as the lub gets on them, and then you are blind and deaf and the heavy black condom suddenly slides down to your shoulders! You scream, unable to breath, struggling and falling tot he floor with a soft thud. As you roll around in a panic, muscles weaken and you feel pressure and heat all around you. The need to breath fades, and you start to feel throbbing, pounding that fills you with pleasure. You are encased in something that vibrates and squeezes, and you finally stiffen and feel a gush that pushes up through your body and erupts from the top of your head. Another gush, then a third.
Then you are released from the curious pressure and feel yourself swinging in the air, getting relaxed. You cannot see or hear, but you have a vague awareness. Very faint images from far away present you with distorted but understandable impressions. You are now the cock of a huge horse, and you have just been 'milked' for semen by a breeder! You feel tugging as the black condom, now a collection sleeve, is pulled off.
