Another abnormally hot day. It's not supposed to hit 85 degrees in freaking March. Well, nothing for it. I stripped off my clothing and lay on top of my bed. I had taken the precaution to draw the blinds and lock the door, of course. No point in getting under the covers, that would just overheat me more.
"You look very attractive. And you've already removed all your obstructing clothes."
I turned my head. A tall, jiggly, orange creature was standing next to the bed. The voice was female and the body, though the form was constantly shifting slightly, was definitively female.
I whacked my palm into my forehead to try and clear the hallucination, while wondering if someone had slipped a psychedelic into my lunchtime water bottle.
"I'm as real as the day is long."
She gently reached down and caressed my cheek. Her body was cool. It felt nice.
"A live slime-girl."
"The name's Marcie."
"Vinny."
"You probably want to know why I'm here. While I can only reproduce by mating with my own species, we slime people find human cum a delicacy, and we often find single humans to have fun with. The slime boys have a harder time of it, because women are afraid we'll `rape' them or something. We're actually a very gentle people, and our males have found that extending a protrusion from the facial area instead of the groin is usually enough to convince the women to let them inside. Apparently human men don't `go down' on them as much as they want. It's all the same to us, we don't have distinctive body parts."
"So, you want to have me fuck you and cum inside."
"Correct."
"So, how many of you are there?"
"About 50 million, scattered worldwide. We get all the sustenance we need from the air, so we do no harm to the environment. Now, enough talk. Right this instant, probably there are 10,000 of us engaged in sexual congress with various humans. Shall we make it 10,001?"
"Please."
Marcie flowed onto the bed, then re-formed into the shape of a woman. I slid over a bit to make room for her. She caressed my face again, then began caressing my chest. Her cooling touch was exactly what I needed on a hot day. I let out soft sounds of pleasure.
"Glad you like."
She then caressed my legs, using the same cooling touch, moving her way upward to my thighs. When she reached my inner thighs, my cock began stiffening.
"Mmmmmm, nice."
She gently massaged my balls with one of her "hands". My cock stiffened the rest of the way. Six full inches of glory, pointing straight up.
"We slime-girls don't need foreplay. I've been ready ever since you got home. I was actually waiting for you under your bed, all day."
With that, Marcie unceremoniously flowed her body onto me, re-forming her female figure with my cock inside her where her vagina would be if she were human.
"Go ahead, Vinny. Start fucking me. I know you haven't had a release in two weeks."
I held the rest of my body still and began thrusting my hips up and down. The sensation of coolness instead of warmth around my pole was different, but it didn't feel bad.
Marcie leaned forward, She had shaped herself so that her "breasts" were quite large. I kissed her skin as they jiggled and flowed slightly around my face. I had expected the sensation to be like kissing Jell-O, but it actually almost was like kissing human flesh.
A new sensation made me glance downwards. Marcie had extended part of her body into a long tendril and wrapped it around my legs several times, trapping my cock inside her. It was too hot to move fast, so I continued my slow, steady rhythm of upward thrusts.
"That feels nice, Vinny."
