Sensual Ballbusting but no Sex (Realistic Fiction - Female Perspective, non-consent)

I'm laying in my partner's bed one night, unable to sleep like I often do. I had tried to initiate sex but he said he was too tired. He never has issues falling asleep and was out like a light.

I'm laying there in the dark for an hour but find myself wide awake and horny. I'm bored and had tried fingering myself but I wasn't in the mood to play with myself when my favorite toys were so temptingly close. If I could just get my hands on them maybe I could relax and get some sleep.

My partner doesn't need to get up early like I do. He works from home and makes his own schedule, he doesn't own a car so I do all of his driving for him. I decide to play with his testicles even if it wakes him up. If he has a bad sleep he can always sleep in.

We are laying side by side on our backs. He is on my right. I reach my right hand under the covers towards him until I feel the fabric of his pajamas that is covering his hips. I walk my fingers slowly down the front of his pajama pants until I feel the top of his soft penis. My fingers creep down until I am cupping his left nut in my hand, that is enough for me for now. I pinch his nut between my fingers and the palm of my hand, feeling it squishing slightly. I hold the squeeze firm for several seconds, slowly pinching harder and harder. I lay quietly, trying to notice any reaction from him but I don't. I don't know if he's awake or asleep but I can't believe I'm getting away with pinching him this hard. I can feel my pussy getting wetter the longer I pinch.

I let go, not wanting to push my luck. I don't actually want him to wake up screaming in pain. I just want to rough up his balls and see how much I can get away with, if he tells me to stop it's game over.

I push his left nut around with my index and middle fingers. I press on the top and slowly slide it around like a checker on a checker board. Then I press down with both of my fingers and lift off. Then I press on them again with both fingers and lift off. Then alternate them, pressing his testicle down with each one like my fingers are marching on his balls. Still no reaction.

I fish around until I have both of his testicles in my hand. I slowly close my fingers around his balls, feeling them compress in my hand. I reach down with my left hand and stroke my clit. My fingers gliding easily from the wetness. I enjoy the sensation for a moment but my focus goes back to my partner's balls.

As I squeeze his balls and finger myself I wonder if he's awake. I squeeze tighter for a few seconds. No reaction. I let go and gently pat his testicles with my fingers, pressing them flat and massaging them slowly as I knead them with my fingertips. Still no reaction.

I reach my hand upwards and lightly touch his hard cock. There's a reaction, but I still don't know if he's awake or not. I lightly rub the underside of his cock and squeeze it a bit.

I love that he's not waking up, this is so hot to me. I think about him laying there, just letting me fondle his equipment for my own pleasure while he pretends to be asleep. I absentmindedly finger myself as I squeeze and prod his testicles. I feel much more relaxed and I drift off to sleep without climaxing. My hand still resting on his crotch.
