Slipping my cock into my sister

Kate's pussy was so wet and warm as I slipped my tongue through her folds. She desired me, I could tell. So after a few more licks I pulled her backwards towards me as I lay back down on the couch.

She was so wet that my dick slid effortlessly into her twat. She moaned as I entered her. And then as I slowly pushed in and out of her her moaning continued. I was surprised if how loud she was when fucking because her sister, my wife, hardly ever made a sound.

"Oh gawd! Yes! Fuck me fuck me!" she kept screaming. Maybe it was the taboo nature of it all or something more but she moaned each time I slid back into her.

I was having trouble with fully engorging myself inside her so I flipped her over, giving myself a better position as I then entered her from behind.

Her ass pointing up towards me almost sent me over the edge, but I held it together as I was determined to extend this fuck as long as I could.

"Wait, I want to see your face as you cum inside me," she demanded. She knew I had been snipped years ago at my wife's request. She wanted what was left of my baby battery to coat her insides. What a turn on!!

I flipped her over and pushed back inside her, pushing as deep as I could, as far as I could. She never lost eye contact as I fucked her. Our skin slapped together with my thrusting but she continued to moan, complementing how good my cock felt inside her.

Her pussy lips rolled back and forth as I pushed deep into her. Hey eyes glued to my face as I began to feel my orgasm approach.

"That's right! Fuck me! Dump your cream inside me. I want to feel you fill me up. I've wanted this for so long!" she continued to urge me on. It was all intoxicating. Her gorgeous naked body, her smooth pussy rubbing up and down my shaft, and constant screams were making me climax.

"Ugh!" I finally said as I pumped harder into her. I could feel my cock explode inside her, coating her innards with my cum. She popped me and quickly began to milk my cock for more jizz. Steam after stream continued to eject across her stomach.

I began to squirm, but she didn't let up. She continued to milk me, trying to drain my balls of every little drop left in them. When I finally pulled away she looked up at my face and ran her fingers through the mess I had covered her in.

She looked pleased with herself. Her finger slid through a creamy white streak across her tits. She pulled it up to her lips and tasted me. "Yummy! I can't wait to do this again," she commented with an evil grin.

Just then I heard my phone buzzing and looked at it on the table. It was my wife! I stepped over and hit the speaker button.

"Hey hun! I hope Kate was able to get what she needed. Is she still there?"

"Umm yeah actually she is," I muttered.

"Hey sis! Yeah I'm just finishing up here. Thank so much for sharing your stuff with me," she said with a dirty grin looking at me.

Wife replied, "Anytime! Really anytime you want you can use whatever you want of mine."

Kate looked at me hungrily while tracing my cum down her chest again.

I smiled and then headed for the bathroom to clean up.
