It turns me on when I knee you in the balls (Realistic Fiction - Unique Female Perspective)

It is a cold night. "Snuggle?" he asks.

I roll onto my side and he spoons me from behind. We are still for a few minutes as he holds me in the dark. Then I start to gyrate my hips and press my ass into his crotch. I can feel it bumping into his genitals. I can tell he's enjoying it so I grind into him harder. I start by rolling my hips to grind my ass into him but pepper in a few hard backwards thrusts with my ass that shove into him head on.

As the grinding gets more intense I can feel him grinding into me too. I reach behind and grab onto his butt and hold him in place as I grind into him extra hard. Then let go and slide my hand between us and feel his dick with my palm. I play with it a bit as I move my hand further down and start playing with his balls through his pants. Massaging into them and slapping them around.

My arm us getting sore from reaching back there so I lay on my side next to him and reach over with both hands to play with his junk. He reaches over to feel between my legs and he can feel how wet I am but it's nowhere near as wet as I'm about to be.

I hold onto his dick with the hand that's closest to him and I let go of his balls. Then I shift my body so it's tilted in his direction and I bend the knee of the leg that is closest to him. I place my thigh so it's resting on his hip and my knee is laying on top of his sack. Then I put my ankle on the bed between his legs. I lift my knee and let it drop sideways onto his balls. I can see him react a bit but I can't tell if he likes it or not. I continue to stroke his cock and move my knee around on his balls. This position doesn't allow for very hard contact. "Is my knee okay?" I ask.

"Yeah" he says.

"Good because it's turning me on" I say as we both notice how much wetter my pussy has become. He rubs my pussy more enthusiastically.

I can feel him stop touching me and he's touching himself as I try to stroke him off. My knee is still in his crotch. I ask if he's ok and he tells me he's just trying to rub some of my wetness on his cock. I reach down and soak my hand with my pussy juices and grab onto his cock. He turns so that his hips are angled towards me.

It is now a lot easier to shove my knee in his balls and we lay there for a few minutes with my knee jammed between his legs as we rub each other off. Then I straighten my leg and turn to completely face him. Now I can knee him with my other knee. I squeeze his cock tightly while I position my knee. I feel it nuzzle up to his nut sack and feel a surge of arousal. I pull my knee away a small distance and then bump it into his jewels. I feel them move around as my knee bumps into them. I notice a small reaction from him, the slightest moan as he holds his mouth open in... lust? pain? I don't know. I don't think I've hit him very hard.

I give him a few more thumps, feeling my knee squish onto his balls. It's so hot to me. I love doing it. He keeps fingering me and doesn't tell me to stop. I knee him a few more times and from his reactions I can't tell if he's about to cum or if he's in pain. I ask if he's okay.

He rolls onto his back and says with lust in his voice, "Climb on top of me Baby."

I start riding his cock, sitting straight up and he reaches out and strokes my clit as I grind back and forth and flex my vaginal muscles. This feels good but I can't do it for very long. He is very slim but my legs are too short for my knees to reach the bed comfortably. As a result, his sharp hip bones are digging into the underside of my thighs.

I lean forward and kiss the side of his neck. I snake my hand under his neck from the other side and hold his head on place as I lay on top of him, humping him and kissing the side of his face. I moan into his ear. My breasts are pressing into him from above.

Eventually I need to change positions. He gets up and stands on the floor next to the bed.

I sit so my ass is on the edge of the bed and spread my legs and lay back. I pull my legs up so my knees are hovering over my shoulders. I can feel him enter me and now it's up to him how hard he wants to go.

*He wants to go hard* He starts thrusting himself into me. I can feel the end of his cock slam painfully into me. I whimper in pain and he keeps going harder, maybe this is payback for kneeing him in the balls earlier.

Once again I imagine I am the man on the ground getting busted and I don't know why. All I know is I can feel someone hurting me between my legs and they won't stop. The end of his cock feels like the hard toe of a shoe jabbing me hard between the legs, going as far as it will go.

I didn't used to like when sex hurt this much but I would often lie there and take it because I didn't want to keep stopping him every time he got too carried away. When I started to associate the pain I felt with ballbusting, I started to like finishing this way.

He is rubbing my clit and it feels good. I wonder if this is what guys talk about in these stories. The pain mixing with the pleasure. The pain making the pleasure more intense.

He's pounding me so hard I can feel the bed move.

In my head I am still the man lying on the ground. My eyes are closed and I can't see anything but I can feel the pain between my legs. I am laying on my back with my knees bent and my legs spread and I am letting her angrily kick me, over and over again. The angle keeps changing every 10 to 15 kicks. I'll start to get used to the pain on one angle only to have it switch and deliver a fresh type of pain.

I whimper and yelp but she doesn't stop. She won't stop hurting my balls until we both cum and she is relentless. "ooo oooo oooo" I whimper endlessly as I feel hit after hit. She's being so mean to me. Why does she like hurting me like this?

I'm getting close. My partner changes angles and I feel him pressing into my g-spot as he flicks my clit. This is a whole different kind of uncomfortable because now I feel like I need to pee. I try not to think about that and just focus on the rhythm of the trusts and imagine someone hitting me between the legs over and over and how terrible and unfair that would feel. Ow my balls, ow my balls...

"UUUUUGH!" I bellow a moan of ecstasy and my partner knows that I'm cumming. He picks up the pace of his thrusting and is bringing himself to orgasm as well. He rubs my clit until I tell him to stop and he thrusts until he's finished.

I get up and look around to find the bed has shifted several inches. I turn to him and say "And we didn't even need to use lube."

*So reader, who would you rather be? My partner or the man on the ground?*
