My Mother In Law Busts Me For No Reason

My wife Robin says I have to put up with her mother, and that she's only going to be here a few more days. But fuck, it's ridiculous. Her mother keeps pretending that I'm peeping on her, and then she beats on my balls. It's bullshit. Robin says her mother is angry about her divorce, and she asked me to take it, because it makes Margaret feel better.

I was trying to do what Robin asked, but it's becoming too much. Yesterday, Margaret got me off by kneeing me in the balls. I told Robin about that too. She didn't seem to care. That seems over the top to me. I'm getting pretty annoyed with the whole situation. I'm walking on eggshells in my own house, just waiting for Margaret to blame me for something and fuck up my balls. To be honest, it's not all bad. Margaret is hot, I mean really hot. Big tits and the same curvy body as my wife, just a bit older.

Robin has been working at her office in the city this week, so it's just Margaret and me at home during the day. I work from my home office, and I've been staying in my office as much as I can to avoid Margaret. I do need to leave it now and then; a guy has to eat. It was getting close to lunchtime, so I poked my head out into the hall. There was no sign of Margaret. I snuck out and headed for the stairs.

"Hey, were you out here waiting for me?" Margaret asked as she walked out of the bathroom with only a towel wrapped around her.

"No, I'm just going for some lunch, I didn't even hear you."

"How can you not hear the shower?" she asked, looking at me indignantly. Of course, that's when her towel dropped to the floor.

"Let me get that for you." I stepped towards her to pick up her towel, but before I could react, her foot shot up into my balls.

"FUCK! Margaret!" I groaned as I dropped to the floor, landing on top of her towel. My balls throbbed in pain, every nerve in my body was screaming in sympathy with my aching balls. It was agonizing. I looked up to see Margaret standing over me, her big breasts swinging as she leaned forward, trying to get her towel.

"Get off my towel!" she demanded. I was still clutching my balls, curled up on the floor. I tried to roll over, but was still on her towel. She knelt down on top of me and tried to roll me off.

"You have a hard on again!" she yelled. I looked up at her big tits, just inches from my face. Who wouldn't have a hard on, but I resisted the urge to say anything. I just lay there waiting to see what she would do next. I didn't have to wait long, she managed to roll me onto my back, then she started undoing my pants. All I could think was, here we go again. This bitch is nuts. Why does she want to do this to me? I lay there passively as she yanked my pants. Robin asked me to take it, so I was trying.

"You have to stop trying to see me naked, it's just not right," she proclaimed. Ironic, considering she just yanked my pants off. "I'm going to teach you that it's not worth it."

I watched in horror as her knee pulled back, then she drove with a thud between my legs and squashed my balls up and into my body. I groaned in agony as she connected.

"FUCK! Margaret, that's enough, stop it."

Her knee came back, this time, I managed to get my hand in the way.

"Move your hand, or I'll destroy your balls!"

"NO! ENOUGH OF THIS!"

"WHAT?"

"NO!"

I pushed her off me, she reached for my balls and missed, I pushed her onto her back and climbed on top of her.

"No more! We're done," I said.

"Stop it, what do you think you're doing?"

I had no idea, but I looked down at her lying on her back with my legs between hers. She's been pushing me around for days, it's my turn to push back. I lifted her legs, she didn't resist.

"What are you doing?"

"I've had enough! It's your turn to be punished."

I pushed my cock into her wet pussy and started fucking her. I was angry, my balls still ached, and I was horny as fuck. Her tits swung up and down as I fucked her, it looked just like when I fucked Robin. It was surreal. I didn't care. I was mad enough that I just lost it. I fucked her hard, our bodies slapping together with each stroke.

"You ... can't ..."

"Yes, I can." I pumped her harder, almost in a frenzy.

"I'll tell Robin."

"So will I."

"I ... " She tried to speak, her face was red, her eyes looked like they were going to roll back in her head. "I'm cumming!" she moaned. It didn't slow me down a bit. I kept fucking her faster and harder. She moaned loudly, then she pulled me into her and cried out. "FUCK YES!"

My cock was buried deep in her pussy, I held it for a beat, and then I went back to pounding her. I felt the orgasm coming, it wouldn't be long. Something about blowing a load in my mother-in-law seemed off to me, so I pulled out and aimed my cock at her tits. I managed a stroke or two and then erupted on her big breasts.

"FUCK!" I moaned, cum shot from me in a torrent, it was so good, so satisfying. Margaret looked at me with her mouth open. I think she was in shock, I didn't care. I took another stroke as more cum blasted from my cock, her breasts were soon soaked in cum. I leaned my head back in ecstasy, it felt so good, so satisfying.

That was a mistake, her hand snuck in between my legs, she got a grip on my balls and squeezed.

"Get off of me, you pig!"

"Ohhhhhhh," I groaned. I was still cumming, the pressure on my balls felt awesome, both good and bad mixed together. "FUCK!" I groaned as another load of cum splattered onto her tits.

"FUCKING PIG!"

"CRAZY BITCH!"

"YOU ANIMAL!"

"YOU PSYCHO!"

"GET OFF ME!"

"LET GO OF MY BALLS!" I was still cumming, yelling, and cumming.

She finally did let go of my balls, she pushed me off her, and I let her. I sat next to her in the upstairs hallway.

"What the fuck did you do to me?" she asked angrily.

"I shut you up, at least for a minute."

"You had no right to fuck me."

"You had no right to squeeze my balls."

"But, I ..." she mumbled. "Oh fuck it, I'll leave your balls alone ... for now."

I laughed, I knew she was full of it. "Then I probably won't fuck you again ... for now."

This was going to be an interesting one to tell Robin. I wondered how that would work out.
