"Just wear me like a glove"

"Just wear me like a glove" you say to her and she smiles:

"I fully intend to. Now show me your ass."

Instead of bending over like she suggested, you instead sit down in the plush chair and then rise your legs on its arm rests, presenting your ass to her. You watch as she takes a bottle of lubricant and puts its to your anus. Then you feel her spraying your insides with it. You start to ask "What are you..."

She cuts you off with, “It’s not exactly an easy thing to take a fist you know.”

She takes a quick lick of your dick and then puts in her mouth, meanwhile playing with your ass opening. She probes you with a finger, then two till she is finger fucking your ass with enough vigor to get your cock to almost blow in her mouth by the time she has all four fingers inside. By comparison the blowjob was almost lame. “Oh god... this isn’t what I had planned.” You say panting. “Don’t do any more, just put them on.” You beg.

“If you think that’s best.” She says, three fingers planted in you, her thumb massaging the rim of your hole. You hear the zipper finish closing on her leg and as you do you see your breasts expanding to something like a B cup, encased in a lacy white bra. You shrink overall but in comparison your legs lengthen and smooth out, covered in matching stockings. Black stilettos with open toes and a slender buckled strap allow you to stretch their 6” heel into air.Similarly your arms are now extended in soft silky sleeves of black and white stretchy fabric with your now slender fingers poking out one hole and your thumb another. Your fingernails lengthen and are lacquered in cute hot pink polish. You can't really see what happened to your body beyond your new breasts, but you see her turn back into the muscular jock she was a while ago.

"There we go" she or rather now he says in his new husky voice. "Nice and stretchy."

With that he pushes his entire fist into your ass. You feel your insides stretch and stretch, and stretch even more. There is no pain and a little pleasure on the very rim of your anus, but otherwise it doesn't feel any different than normal. You try to look down and see what did she (he) do to you, but all you can see is a giant bulge of your tummy, with a hand print clearly visible - from the inside.

"What..." you try to ask, but suddenly you feel another hand pushed into your ass. So you simply moan instead.

"Well, you wanted me to wear you like a glove" he explains "and as gloves are both empty inside and very elastic, so are you." You feel him push his second arm further inside and your anal opening stretching to allow this. "And now I will simply slip inside and wear you like a glove."
