My Wife's Sister

... cock slowly into her all the way until my stomach was pressing against her ass. “Mmmmm! You’re so big and hard! Fuck me good! I need it. Make me your slut.” I fucked Mari for an hour at least, making her cum four times. After the third time she begged me to stop, but I kept going. Sweat was rolling down her face as my cock unloaded into her body. I collapsed beside her and fought to stay awake. I was more exhausted that Mari was, but I still wanted a good blowjob. She whispered, “That was amazing, Charles. You made me beg you to stop. I’ve never done that before.” “I still want a blowjob to remember you by.” “Okay. Give me a minute,” she said, still trying to catch her breath. After about ten minutes, Mari went to the bathroom to comb her hair, then returned and asked me to stand up. “Let’s pretend that it’s tomorrow and you’re all dressed up in your tuxedo ready to get married and I slip into your room and give you a quick blowjob.” As I thought about that, I said, “Wait a second. Let’s really do that tomorrow. Right now you need to get back to the house. “Oh, Charles! You are as naughty as I am!” “So you want to do it?” “Of course! Where will you be before the wedding?” “I’ll be in a class room in the school building. Room one.” “Okay.

I finally told her that I needed to pee and left.” “Well, you’re here now.” “Oh you look so handsome, Charles! I’m going to give you the quickest and best blowjob you’ll ever have. At least until I visit you again.” With that, Mari dropped to her knees, unzipped my pants, and pulled my cock out. It was only half inflated as she popped it into her mouth and started to suck. Within half a minute she had it hard, so she started to bob up and down on it, pushing it down her throat all the way until she gagged, then pulling up and pushing it down again. Over and over she gagged on my cock as I held her head tight. She had her hair up in a bun again and as I looked down at the top of her head, I tried to imagine being married to her instead of Aimi. That made me start to cum immediately. My cock shot long squirts of cum down Mari’s throat, making her cough when it hit the back of her throat. But she kept sucking and swallowing until she had consumed every drop. Then she stood. “I hope that was good for you, Charles. It was a fantasy of mine ever since Aimi told me she was getting married.” “I’ll surely never forget it.” “And I bet I give head better than my sister does.” I didn’t answer as she slipped out the door.
