Fucking my pregnant sisters pussy

I walked up to the door of my sister Kirsty’s house, my heart pounding with excitement to see her and her new baby. She opened the door with a massive smile, and I couldn’t help but notice the obvious bump of her pregnant belly. Her tits looked so big, too, full of milk.

“Hey, sis!” I exclaimed, giving her a big hug. “You look amazing!”

Kirsty laughed and rubbed her belly. “Thanks, I feel like a whale. But I’m so excited to meet my little one.”

We went inside and sat down in the living room. I couldn’t take my eyes off her belly, fascinated by the life growing inside her.

“So, when are you due?” I asked.

“In about a month,” Kirsty replied. “I can’t wait!”

As we talked, I couldn’t help but feel a little jealous. I’ve always wanted to be a mom, but it hasn’t happened. But seeing Kirsty so happy and excited made me happy for her.

After a while, she excused herself to go to the bathroom. I took the opportunity to explore her house, looking at all of the baby stuff she had already set up. It was all so cute and tiny.

When she returned, she sat beside me on the couch. She was a little uncomfortable, her belly pressing against the armrest.

“Do you want to feel the baby kick?” she asked, smiling.

I nodded eagerly, and she lifted her shirt, revealing her round, bare belly. I gently placed my hand on it, feeling a little fluttering movement.

“Wow, that’s so cool,” I said, my eyes wide with wonder.

We sat there for a while, talking and laughing, and I couldn’t help but feel a little broody. I wanted a baby of my own so badly.

But for now, I was happy to be an aunt and to support Kirsty through her pregnancy. And who knows, maybe one day it will be my turn.

As the evening wore on, I couldn’t help but feel a little tired. I yawned and stretched, ready to go home; I started to get hard for no reason.

“I should get going,” I said, standing up. “But it was so good to see you.”

Kirsty gave me a hug, and I left, grateful for the time we had spent together. She felt it pressing against her.

“I thought it was pregnant women who get horny,” she chuckled. “Trust me, I am horny all the time; my hormones are all over. You can stay longer if you want; I can see to your little problem.”

I couldn’t believe what I was hearing. I looked at Kirsty, my heart racing, and she smiled mischievously. “I’m serious, you know. I could give you a little release. That’s if you want to fuck your fat puffy sister’s pussy.”

“‘Y-yes,’ I stuttered, surprised yet utterly turned on by my sister’s bold offer. I had never thought of her in that way, but now that the possibility was there, I felt my cock throbbing to life.

“Good,” Kirsty purred, reaching down to unbutton my pants. She pulled down my zipper, reaching inside to pull out my hard cock. Her face lit up with surprise.

“Wow, you’re quite big,” she whispered, stroking my dick gently. I couldn’t believe what was happening, but I wasn’t about to stop.

“I have a condom,” I said, reaching for my wallet. Kirsty nodded, took it off me and threw it.

“I am already pregnant, so a condom is no point, besides don’t you want to fuck my pussy raw,” she said, pulling her skirt up and bending over.

“Fuck, yes, I do,” I growled, my hands gripping her hips as I lined up my cock with her wet, hairy pussy. I couldn’t believe what was happening, but I wasn’t about to stop. I slid in, feeling her tight, wet heat envelop me, and I couldn’t help but groan with pleasure.

Kirsty moaned as I started to fuck her, her tits bouncing with every thrust. She reached down to play with her clit, her fingers working in time with my thrusts.

“Oh, fuck, that feels so good,” she moaned, her voice getting louder and more breathless as I pounded her pussy. I could feel my orgasm building, but I didn’t want to cum yet. I wanted to make this last as long as possible.

“Don’t cum yet,” I panted, slowing down a little. Kirsty whimpered in frustration, but she nodded. I started to fuck her again, slower and deeper this time, savouring every inch of her pussy.

We went at it for what felt like hours, our bodies slick with sweat and our moans filling the room. I could feel my orgasm building again, but I held back, wanting to make this last as long as possible.

Finally, I couldn’t hold back any longer. I groaned as I felt my cock swell and pulse, my cum filling Kirsty’s pussy. She moaned as she felt me fill her, her pussy clenching around my cock.

We collapsed on the couch, panting and sweating. I couldn’t believe what had just happened, but I knew one thing for sure – that was the best fucking I had ever had.

“Wow, that was intense,” Kirsty said, smiling at me. I nodded, still too out of breath to speak. I knew one thing: I couldn’t wait to do it again.
