"Take off your clothes," the researcher says. I do as he commands, feeling my nipples harden and my pussy tighten as he stares. He tells me to get up on the examination table and lie back. The pleather is cold against my skin and my nipples get harder still.
"Bring your knees up, ankles together, and then open your legs." I do as I'm told, suddenly embarrassed at how hairy my cunt is. He peers at my pussy and makes some notes.
"How often do you masturbate?"
I blush. "A couple of times a day." He doesn't say anything, but puts on some rubber gloves. His fingers part the hair and delve into the folds of my labia, pulling them apart to reveal my vagina. He runs a finger around the rim and then he moves to my clitoris, pulling the hood back and moving his finger over the tip. I shudder but he stays silent. He squirts some lube onto his hands and proceeds to insert a couple of fingers into me, feeling around inside. He tries three fingers, then four.
"Put your feet in the stirrups." I do as I'm told. The stirrups are fairly far apart, my legs won't go much wider. I am fully on display. He tries the four fingers again. "Mmm. Better."
The door opens, and a group of people enter. I'm completely prone but they don't really give me a second look, they're only interested in my pussy. The researcher invites them over as he wheels over a table with various objects on it - the objects are a range of shapes and girths and I realise what they're for.
"I thought we'd start with seeing how quickly we can get her stretched enough to accept the smaller items," says the researcher. The others nod and murmur. "How many fingers at present?", one asks. "Four. She masturbates at least twice a day with dildos so the pussy is well used." He demonstrates by sliding his fingers into me, as far as they'll go. "I will now attempt to loosen the vagina to insert my full hand." He moves his fingers in and out, increasing the speed. I feel myself beginning to get aroused and my cunt makes some interesting noises as he works.
Suddenly his fist is inside me and my legs automatically try to close around it, but the stirrups hold them apart. He moves his hand in and out, adding more lube. Feeling him inside me is making me so horny. I can feel my wetness sliding down my vulva. He stops and withdraws his hand, running his finger around the opening to my vagina and then pulling the two sides apart. "The vulva is now quite swollen; I think she is ready. Let us try this item first," he says, reaching for a bulbous object that's bigger than I was expecting: a large aubergine. He coats it in lube and attempts to push it inside me, but I'm not stretched enough yet. I eye it greedily - I know what it will feel like when he does get it in. Instead he chooses a clitoral stimulator. "Let's masturbate her to aid with arousal." He places it on the end of my clit and switches it on to a low setting, holding it in place. The buzzing runs through me, stiffening my nipples again. I expect him to take it off before I cum, but instead he keeps it there until the orgasm pulsates through me; they all watch my pussy convulsing. I realise later that this is to prepare me for squirting.
He takes a smaller object, a dildo, and pushes it into me. Easy. Something bigger. If he encounters resistance from my cunt, he adds more lube and fucks me with the object until my pussy willingly accepts it. Soon we are ready for the large aubergine again, but again he can't push it in, even with more lube. So he tells me to squat while he holds it beneath me, and I lower myself onto it. The stretch is something else. I feel the rim of my cunt prickling as it widens over the bulbous head. Bit by bit the vegetable eases in, but just as I'm sure it won't go any further, my cunt can't stretch wide enough, it sucks it up and all that's visible is the tip poking out of my pussy. The group help me lie back and put my legs back in the stirrups. I feel completely stuffed but also really aroused again. I know what's coming as he reaches for the stalk; he pulls it towards him and then pushes it back in before it can pop out; he speeds up and I feel another orgasm building. He stops.
"Birth it," he commands. So I bear down and attempt to push it out of me. At first it won't budge, but then I feel movement. The group are watching my cunt, which must be dripping by now. I push again, and again. It moves, but then goes back in. "I will masturbate you again, and as you cum, you birth it, OK?" My clit is so stretched over the aubergine that he barely needs to rub it to get me off. The orgasm builds again and it's like nothing I've ever known. I cum hard, and push with all my might to expel the aubergine. As it leaves, my cunt pulsates with the orgasm, gaping wide from the vegetable's girth. I can feel how wet I am.
"Now we see if this prompts her to squirt," the researcher says, once my orgasm has died down. My legs are shaking and tingling in the stirrups and my pussy feels battered. The group stand back a bit as the researcher parts my pussy lips and begins massaging my clit. "Will someone please attend to the nipples?" A man stands behind me and begins flicking and rolling my nipples with his fingers. The researcher puts his fingers inside me and massages my g-spot; the sensations are too much to bear and I cum again, squirting onto the table and shuddering in the stirrups. Is it all over? Can I get dressed?
"No, you must have intercourse with a member of the group to test the vagina post-stretching," the researcher says. A man comes forward, his large, erect cock clearly visible under his trousers. He releases it and slides a condom on. The researcher lubes me up again and the man enters me, fucking me slowly. "The subject is distinctly loose, as expected," he reports. "It may take a while to reach orgasm." He fucks my pussy in a robotic manner. After a few minutes he begins to speed up and I can tell he's getting closer, as am I. He pounds me hard and I feel his cock twitch, releasing his load. As he withdraws, the rest of the group lean in to see whether my cunt still looks stretched; they murmur to each other. I haven't cum, so I reach for my clit and wank for them one last time.
