“NOOOOOOO” she wailed, but with just a pumps in and out, I could feel her cunt squeeze hard around my fingers. She started to scream but I brought my ball sack down onto her mouth and she sucked on it like a soother. As she un-tensed I had had enough.
“Ok, you’re my sister-in-law, but more importantly, you’re my little slut. You are here for me to fuck, got it?” And with that, I quickly changed positions and drove my cock into her.
“Oh YES, fuck me, rape me, do what you want with me” she grunted with each trust. I banged away at her thru her multiple orgasms. She was a rag doll now. I drove harder and deeper without resistance. Harder and harder I banged away at her. My balls were coated in her juices and I could hear them slapping away at her ass. Finally, I could feel that all too common now tightening feeling. She was going to get the freshest sperm yet. I grabbed legs between my arms opening her up wider than ever before and allowing me to go the deepest depths of her womb ever. I started to growled and it got louder. Unbelievably I could feel her getting tight. She was going to cum with me. She started screaming and growling and I growled even louder as I felt the explosion to happen. She screamed “YESSSSSSSSSSSSSS”, as she came feeling the first spurt of cum, I drove him in as far as I could and with a loud growl/groan I let blast shot after shot of burning hot cum. I could feel it splashing against her cervix. She just kept yelling “YESSSSSSS”, “YESSSSS”, “YESSS”.
It was done. She was bred. I slumped down on top of her. Ever so slowly my cock, done for the day, softened until it came out with a “pop”. I felt our cum flowing out of her and over her unused ass.
“Susan will be home soon”, I said, “you better go take that off and put it away and get cleaned up. You look like a slut”.
“But I AM a slut big brother, I am YOUR slut!, she said with a smile and dried cum still on her face. She got up and more cum squeezed out of her cunt and ran down her leg. “What are you going to tell her about her baby doll pjs?”
“I don’t know”, I said, “what are YOU going to say about them; YOU are the one that wore them?”
She just looked in disbelief and then said, “ok, I’ll think of something I guess”. And with that she went, on wobbly legs, to the bathroom. I heard the shower come on. She was in there for a VERY long time, but eventually came out just wearing a short thin t-shirt.
“I better go put some shorts on I guess”, as she looked at my cock.
Before either of us could say or do anything, susan came in the back door. “I’m home, I hope you two didn’t kill each other” she laughed.
Jo quickly ran to her bedroom and put on some shorts.
Jo had to go home the next day. Without susan seeing, when I hugged Joe, I squeezed her ass and she squeezed my cock. “oh that’s nice that you two can finally get along”, susan said. And with that Jo was gone.
It turned out we had to postpone the wedding for a several months. Days before the wedding Jo came back to help susan with the final preparations.
“You are putting on a few pounds there girl”, susan said when she saw her baby sister.
”I’m not fat silly, I’m pregnant!”, she said.
“I didn’t know you had a boyfriend”, susan said.
“Oh I don’t; it was a one-time thing with this guy I know” Jo said
“Geeez, you must have got pregnant shortly after leaving here” susan said.
“Ya, I guess that is about right”, Jo said looking at me and touching her swelling belly.
