I finished up my work for the day, so I went downstairs to turn on a game. My stepdaughter Marley was way ahead of me; she already had a game on, snacks set out, and a glass of lemonade waiting for me.
"Wow, thanks, Marley. This is awesome."
"I knew you would be done with work soon. Besides, I want to chat with you some."
I had a pretty good idea what she wanted to chat about. Yesterday we were talking, and I let it slip that I liked having my balls busted. She punched me in the balls, and eventually I came. It was nuts.
"Sure, Marley, what do you want to chat about?" I asked, trying to act nonchalant.
"Your balls."
"Ha ha, very funny."
"No, really. I want you to explain to me why you came when I punched you in the balls."
"It's complicated, I'm not sure I can."
"Try."
"Well, it does hurt. It hurts like hell, but it's also exciting. It's forbidden and dirty, and yet I always get an erection. The mix of pleasure and pain is intoxicating. I felt like I lost control of my body, and then I just came."
"You really liked it, right?"
"Oh yes, it was amazing. You fulfilled one of my fantasies, but we shouldn't do it again."
"Why not?"
"Because it's like cheating on your mother."
"It's not cheating, no one is having sex."
"Uh, you realize that when I orgasm, it's me having sex."
"Yeah, but we're not fucking or sucking or any of that stuff."
As we talked, she turned toward me, sitting sideways on the couch next to me. My pants did nothing to hide my erect cock. This talk was getting me hot. I wanted her to do it again, but we shouldn't. My eyes wandered over her body, her big breasts were barely concealed in her tight tank top. She is so hot. When Marley lifted her foot up onto my lap, I knew there was trouble brewing, but I didn't push it off. She pushed her heel into my cock and balls as we talked.
Her foot pushed and prodded my balls, I soon had a raging erection. I felt like I was losing control, and I desperately wanted this to happen.
"Turn towards me and spread your legs a little more."
I shouldn't, but damnit, I couldn't stop myself. I turned towards her and let her foot push between my legs. Her heel pushed into my balls, and the ball of her foot rubbed my hard cock. It felt so good. My breathing was soon getting heavier.
"Are you going to cum?" she asked as she pushed hard on my balls.
"Probably, it feels good."
"Even if I push harder?" she asked as she grabbed my ankles so she could jam her foot into my balls.
"Fuck," I groaned. "That feels amazing."
"Doesn't it hurt?"
"Yes," I winced as her foot mashed my balls into my body.
"I'm crushing your balls."
I felt sweat break out on my forehead. It was true, she was crushing my balls, but she was also massaging my rock hard cock.
"Can you cum for me?"
"YES!" I moaned loudly as my cock suddenly couldn't take any more. It throbbed as I blasted cum into my pants. Again. Fuck! I pulled her foot into my cock and balls, rubbing them with it. "OH, MY GOD!" I cried out as my cock just went insane, cumming and throbbing, making a huge wet spot in my pants.
She giggled as I came, clearly enjoying herself as she mashed my poor nuts. Her foot worked over my cock and balls until there was no more cum left. She finally pulled her foot away as I struggled to catch my breath and regain my composure. Holy fuck, that was hot, but it felt so wrong too.
"That was even more fun than punching your balls."
"Yes, for me too," I panted.
"Next time, I want to squeeze them. I need to feel them in my fingers while I squash them."
I want that too. More than anything.
