My Stepsister Offers A Compromise

This is going to sound nuts, but my stepsister Lisa let me use my own car last night. All I had to do was eat her pussy, and she gave me the keys, but she wants them back today. It's insane, but if I don't comply, she'll take it out on my balls. She owns me completely at this point. I do whatever she wants, because if I don't, she'll squeeze my balls harder than I ever thought possible. The pain is just overwhelming, almost mind blowing.

I'm oversimplifying things a bit if I leave it at that, because there is more to the story. I like it when she dominates me, and I can tell she likes it too. I get these crazy erections when her hand is squeezing my balls. Sometimes I cum just from being squeezed. It's nuts. It's also awesome. I cum so hard that I see stars.

I walked over to her room. I was a little nervous that my balls might be in trouble, I had to give her back my car keys.

"Hi Lisa," I said as I knocked on her door.

"Come in, Matt."

"I have the car keys."

"Good boy," she said as she stood up and walked up to me. "We need to talk, come sit next to me on my bed." She walked over to her bed and sat at the foot. I sat next to her.

"So, Matt, I'm done punishing you for making me blow you when I needed the car. I just wanted you to feel what I felt when you humiliated me."

"Yeah, sorry. I was being a dick."

"Well, yes, but I kind of liked it too."

I looked at her sheepishly, "Me too. It's hot when you dominate me."

"I think so too. I have a new proposal for how to share your car."

"Yes?" I wonder what this could be.

We can split the car, but ... every time the keys change hands, the person taking the car has to offer a sixty-nine."

"Wait ... really? Like right now, since you're taking the keys from me, you have to offer me a sixty-nine."

"Yes."

"Fuck, yes."

"I thought you might like this arrangement."

"I do ... but ..."

"What? What's the problem?"

"Would you still squeeze my balls?"

"Oh, I won't give that up. You can count on it."

"In that case, here are my keys," I said as I handed them to her.

"Would you like to sixty-nine?" she asked, she was already unbuttoning her blouse.

"Let me get that," I said as I reached for her blouse. I unbuttoned it the rest of the way and spread it open to reveal her big, soft breasts. "I would love to sixty-nine." I reached around her to undo her bra, and her breasts spilled out. They looked magnificent. She is really a sexy woman. Probably better than I deserve.

I finished undressing her, then she did me. My cock popped up eagerly as she pulled my boxers off, ready for action. She pushed me onto her bed, then climbed on top of me. She sat between my legs and took my balls in her fingers.

"Just a little warmup first, right?"

"Yes, please," I moaned as her fingers pushed into my balls. It hurt. It felt so good. My cock was so fucking hard already. She leaned forward and licked the head of my cock, then she sucked in just the head. Her tongue traced around it as she sucked on it. She let go of my balls, she ran her finger down to her pussy and ran it along her clit, then she licked her finger.

"I'm ready for you."

"Me too."

She turned around and then lowered her pussy onto my face. I kissed her clit, then ran my tongue along her pussy lips. She tasted sweet. I felt her squirm as I licked her. Her fingers re-grabbed my balls, she began squeezing and kneading them. I moaned under her, but then I felt her mouth on my cock. Oh fuck, it felt amazing. Her soft lips and tongue gliding around on my cock, and her fingers kneading my balls. It couldn't be any better.

I felt like I lost control of my body. I wanted to hold out. I wanted to do this all day, but it just felt too good. I had to give in. My entire body tightened, then my back arched, and I lifted Lisa in the air as I blasted a load of cum down her throat. She took my cock deep and squeezed my balls, my cries of ecstasy were muffled by her pussy. My cock throbbed in her mouth as she sucked the cum from me. My balls ached as her fingers mushed them flat. It was perfect. She sucked it all from me, then let my cock drop from her mouth. She let go of my balls and climbed off me.

"You came fast," she said.

"It was so good, I couldn't help myself. Let's finish you off."

"Yes, we should." She climbed back onto my face, this time facing forward. I looked up to see her big breasts over my face as I began licking her pussy. I put my hands on her ass, and I squeezed it gently. All the while I licked and sucked on her wet pussy. I ran my hands up her sides, then around to her breasts. They felt so big in my hands, so soft and yet firm. I cradled them, then I gently pinched her nipples in my fingers.

"Fuck ..." she moaned. Her legs tightened around my head. I pinched her nipples just a bit harder. "FUCK YES!" She squirmed over me, she pulled my head between her legs. "OH FUCK YES!" Her wet pussy covered my face in her juices. "FUCK MATT!"

I licked her clit until she couldn't take it anymore, then she climbed off me and sat next to me with a dazed look on her face. I was sure I had that same look.

"We're going to have to give the car to each other a lot."

"Yes ... yes we are!"
