Sex with My Wife's Sister

Kate tells me about all the cool clubs she goes to over the weekend and I get jealous thinking of her with another man. She never mentions that part and I don't ask. Still, I know she's been with others. How could she not? You'd just have to look at her, she's so hot. What guy would not hit on her?

So, there we were a year later sitting on the same couch watching television while my wife napped. I can't believe it's been a year that my wife's sister and I have been having sex.

"Joey, since this is the one year anniversary of me blowing you, I thought I'd celebrate the date by sucking your cock now."

God, I love this woman. She's so thoughtful. I looked to where my wife slept soundly in the bedroom. The door was tightly closed. One never to resist a blowjob, I agreed to having her sucking me off, again. Definitely, after I'm done cumming off in Kate's mouth, I plan on telling her that we are over. I'm done. I can't do this anymore. It's wrong.

As if it was the first time all over, again, she reached her hot hand down, unzipped me and pulled out my cock. I helped her by scooting down my pants to my knees. I didn't want to take them completely off, should my wife suddenly awaken.

Kate was all over my cock, as if she was a toothless, starving woman sucking on a kielbasa. I unbuttoned her top and pulled out her tits. There's nothing like feeling tits, especially her magnificent tits, while getting a blowjob.

"That's right, suck it baby. Suck my big prick. Yeah, stroke me. Blow me. I'm getting ready to cum in your sweet, pretty, little mouth."

"Joe! Kate! What's going on here?"

I opened my eyes and couldn't believe Susan was standing right there behind the couch staring down at us. I must have zoned out while cumming in Kate's mouth. I never heard her. She caught us. She caught Kate sucking my cock. She saw her sister blowing me. When I pulled my cock from Kate's mouth, there was a clothesline of cum hanging from my cock to her lips.

Now what do I do? What can I possibly say to fix this? I'm so totally fucked.
