"Yeah, make it tighter"

I say the words loud and clear, they jumped into my brain as I was trying to think of a good way of saying 'play with my pussy' but they just didn't seem right. I'm rewarded instantly his my helpers finger slides further between my crack, his fingertip pushing against my clit. My body contracts a little in dual pleasure and pain, an intoxicating mix of sensations.

His fingers withdraw back between my lips, curl up slightly and two fingers push into my extremely tight kitty. I let a light moan go, and then let a louder gasp of pleasure out which is echoed back as a cheer from the rest of the shop. The fingers slip back out easily, my entire groin so tight from the heavy balls still wedged into my ass. My helper shifts across to reach the other toys on the counter and says.

"I've come across virgins more lax than that."

I smile and consider saying something about me still being a virgin but don't want to create a scene; after all I'm naked in a sex shop, after sucking off four guys and taking a massive set of anal balls into my behind so they wouldn't believe me anyway. I feel the head of the vibrator press against the entrance to my kitty, it is warmer than I thought it would be and I'm sure it was a hard plastic rather than softer jelly style.

His move is sudden and knocks the breath out of me, I try to inhale but can't for a second giving me a chance to process what has happened. Part of me knew the moment I felt it against my sex that it wasn't a vibrator or any other sex toy, and with one swift and directed thrust of his hips he's taken my maidenhead. More than that, it went in. The tightness in my entire groin borders between a thin line of unbearable and unbelievable. The roar in my ears breaks into the cheers of my loving audience.

He slides back out a little and then back in, slowly starting to fuck my nineteen year old, recently virgin cunt. My fingers claw into the counter and I manage to take a mouthful of breath, my mouth still one set behind as I quietly slur out an incomprehensible gaggle of words that was supposed to be 'take it slow' and 'be gentle' at the same time. The words I hear though, loud enough that they are clearly meant for the room and not I, are.

"This is so tight, I can feel the balls in her ass pressing against my cock. It's not just tight near the hole, it like a perfect fucking vice all the way down. Shit its good!"

With each thrust in and out I can feel my entire ass shift from the inside, as he pushes deep into me I can feel the balls clump up around my butt hole, a pressure of them wanting to escape. But then as he draws back he frees up some space inside me, the smaller balls at the end trying to fill it and the larger ones following. How it seems appears to be how it looks as the messy clerk says.

"Look at her butthole as you fuck her. That is awesome. I've got to get a video of that."

My head laid on the counter, looking at framed posters of the 'golden age of porn' when entire adult cinemas were widespread to the borders of mainstream, before the home video market came about. I see the clerk reach under the counter and bring up a phone and I can hear the shuffling of feet as the audience moves in closer for a better look at whatever my ass looks like.

I can feel my climax approaching, unsurprisingly completely different to anything I've experienced before. The rumbling combination of pleasure and pain in addition to having a cock, a real man cock, bring this on. It grows, not like a flower or a fire, but like volcano with an eruption of pleasure that in the back of my mind I consider might actually hurt me. My orgasm is brought short though as I feel my helpers cock spasm in me, followed by his whole body as he punches his dick in deep. The crowd seem to enjoy the effect this has on my butt from their shouts but the sudden shot of additional pain freezes me in place.

My body on the cusp but his cum dampening it, his shaft pulls out from me and I suddenly feel a little more empty, the balls in my butt shifting back to try to fill the void inside my teenage body. I'm on the cusp of my first 'real' orgasm from a real man, not an orgasm brought on by my own fingers and toys, but my body is crying out for both me just releasing myself with my fingers as I have done so many reliable times before and for the pain in my buttocks to end. I hear the clerks voice again.

"Jesus, look at the cum. Her body is just pushing it out of her. It must be too tight in her cunt even for cum!"

With cum spooling around my lips and my stretched ass begging for forgiveness what do I do? I so desperately want my body to orgasm around a man cock, but also don't care how my orgasm comes as long as it is soon. I'm also not sure my body could take more fucking let alone an full blown orgasm with these balls inside my butt.
