It was customary to press the button to remove the privacy barrier just before the sex began.
Well, we'd fucked once, but the building demand of more, more, more, was growing loud inside me, and I could see the same fucking glint in her dark black eyes that I had seen while she was rubbing a gorgeous tentacle against me, her damp skin shimmery and colored like sunlight shallow gray-blue-green water.
The secret stolen orgasms were nothing but mere carrots over our heads of what we could do next, and every second of denial was fucking torture.
That's why Eve slipped her webbed thumb against the button to raise the curtains. She must have wanted this foreplay on full display, too.
I'd never thought about it before. Never thought about what it would be like in detail to be the volunteer scientist on this side of the observation panel.
They were anticipating our fuck. Watching every moment, analyzing every body movement, to see when it would begin. They just couldn't help themselves.
I realized I really, really liked the attention.
Round two started off slow, very slow: a tempting tease of both our observers and ourselves.
"You ever been with a human?" I asked, listening to the quiet hum of the mechanical removal of the curtain, exposing the almost entirely reflective wall through which my colleges would be observing us, taking note of Eve's alien mating rituals and the sexual interactions between one of us humans and one of her kind.
I shared a large sofa chair with her, our thighs touching, my chest puffed to maintain an air of professionalism. It wasn't my fault if her eyes kept drifting downwards to my boobs, veiled by my thin white t-shirt, crinkled from the bundle it was left in after the first round. I hadn't put back on a bra. Why would I put one more barrier between us? My nips pressed against the fabric, perky and hard.
My eyes weren't drifting to hers, fat and large and beautiful and exposed by her constant nakedness. They were shamelessly settled.
"No," she answered, fighting back a smile, and fighting it hard. "Definitely not."
"Incredible," I answered, and tapped my chin thoughtfully. "Small talk, small talk, small talk."
"I'm really bonding," she answered, losing the fight to laughter. "This is great. I'm learning a lot about you. Really painting a picture."
"Of course. Impressions count."
"Been with an alien?"
"I wish," I sighed dramatically, as if she hadn't just rocked my world.
"Hmm." She smiled. "I bet you don't make adorable little noises, do you? I bet you wouldn't look irresistible if you were in front of one. I bet you wouldn't..."
It was like devouring a meal: I slid my tongue out from between my swollen lips as she watched with interest.
And then she hooked each arm around my knees and pulled me suddenly from the sofa, and I flailed a little in surprise, my legs still confirmed to her firm grasp in the air. The plush carpet softened the gentle thump of my back against the ground. "Wh--"
She dragged me towards the wall with the mirror with single-minded determination, shoving furniture out of the way with her shoulders, foot, knees, body, whatever part she could easily thump against it, her eyebrows furrowed in concentration and focus. "Eve?"
My shirt bundled and rose up from the friction to expose my bra-less tits within seconds, and I felt the rush of wet to my legs at my aroused body being even further on display in front of Eve, and in front of my coworkers. I laid a palm over a nipple and rubbed, a gentle, aching throbbing from my vagina picking up pace.
Eve finished dragging me, her own back nearly against the mirror where my coworkers and the observation team would be on the other side of the wall, probably recording all sorts of notes and details and watching. Watching, watching, watching. Eyes locked on us and us alone.
I would bet anything they were, at least a little, aroused at the display. A massive elephant in the room that silenced everyone and everything. And the idea turned me on.
Eve dragged me around and shoved my cheek against the glass, one long tentacle wrapping around my right leg, exposing myself further to her. I felt her hand between my neck and back, pressing my upper body down into the ground, keeping me just right where she wanted me.
"Fuck," I begged, closing my eyes and applying more pressure against the glass, loving the vision my smashed cheek surely was. The desperation and roughhousing. "Fuck me. Fuck me, Eve. Fuck me. Shove a fucking tentacle in. Shove--" She teased at my clit with her appendage, just a tiny, flickering thing, warm and wet but barely any pressure or friction. Just a tantalizing hint of what she could do. The throbbing worsened. God, she turned me on.
I shut my eyes. "Please," I moaned, too out of it to bother to close my mouth after, panting hard. Jesus, I was probably even drooling. The sweat made me feel hot and bothered enough all over.
I could picture it, picture my image, up close and personal against the window. What a sight I must have been. My boobs buried in the carpet--I bet they could still see my nipples peaking out. I felt almost as if I was observing myself.
My face was flushed, pathetic, red all over, and probably swollen. The tip of her dripping tentacles pried away my labia and pressed around the opening to my vagina in deep, slow circles. I stuck my ass out further in the air, her grip with her other tentacle adjusting to me and then tightening, and I tried to buck against her to get her in, to get her fucking inside me.
"Sec--second hole," I groaned, in case she needed an anatomy reminder.
She shoved what must have been a thousand fucking inches of tentacle into me as if to answer, I know.
I want to say I cried out but I fucking screamed, trying to dig my nails into the surface of a mirror, and instead dragging them down to grip onto the fiber of the carpet. "Fuck! Fuck! Fuck--" So different from anything human, sex toy or otherwise, it was thickening and all-filling and I was fucking stuffed like I would burst. Every nerve in my body felt stimulated, and I honest to god think I fucking began to cry when the tentacle helping hold my body up wrapped higher up my thigh and stretched further, further, until she was rubbing and flicking gently against my clit, her breaths heavy, heavy.
