I get home late from work (as always) and my wife askes me if I could help her brother move. I don't like him and his wife but I was tired so I agreed.

 I drive 50mi to there house. I arrive to find there isn't a damn thing packed. His wife, Casey( 5'5" 185 lbs 40DDs. Big girl but in the right places and solid) apologizes for him not doing anything and gets me a soda. Three hours go by and we almost got everything packed. We are all getting hungry. SO I say" Hey Jason I'm buying lunch what do ya want." Nothing he said. He said " Casey will take ya since you don't know the town."

  We get in her new car and decided on Chinese. As she was in there getting the food A piece of paper caught my eye. It was a letter to her friend. It stated that she was tired of being married to a loser. " Only reason I hang around is for security. Its not for his little dick thats for sure. Hell I have to think of his brother-in-law Billy when we have sex". My jaw hit the seat cause I was the Billy she talked about.She came out of the food joint. I huuried, put the note back and she got in. As we drove to her house I asked " So how long have you wanted me". "Ever since we got married she replied".

 Kinda sucks were're both married I said. She pulled in this alley right behind her house. She shut the car off and kissed me and I returned the favor with a deeper kiss. " Nobody needs to know" she said and put her hand on my now swollen cock. "DAMN" she gasped. Seven? Eight and as big as your wrist I replied.

  I had her shirt pulled up and her bra folded under her massive titties and sucked on them like a newborn. Her tits definitly overshodowed her belly which was a good thing. She shimmied out of her shorts and her pussy scent filled the air. I reclined the seat and she took my cock down her throat till she gagged. She brought her head up swirling her tounge around my shaft. My dick grew even bigger. Now at its full lenght and gurth she had a hard time deepthroating me.

 She sucked my dick for what seemed like an hour. All the while she had a tight squeeze on my balls whith her hand. She pulled her head off my dick with a saliva induced "SSSLuURP!" She gatherd all the spit she had left and and let it fly all over my prick. " I need that in my pussy NOW!" she said. "And don't hold back!" Her window was rolled down so she leaned out the window so her head and fat tits were hanging out. Her left leg was on her seat and her right leg was by the shifter. I had a perfect view of a big ass and a camel toe.

 I positioned myself and guided about 5" in her cunt. OOOOHHH! she cried out. I made about 10 slow strokes and then fed her all 8 1/2" in one  very hard thrust! OHHHH FUCCKKK! She gasped. Knowing we've been gone awhile I know what I had to do. I grabbed two hands full of her big ass and started to jackhammer the shit out of her. "FUCK YEAH FUCK YEAH FUCK THAT BIG TIGHT PUSSY!" FUCK YOUR SISTER-IN -LAW GOOD YOU SONOFABITCCHHHH!!!" God damn i'm cumminnnggg she screamed. I stuck 2 fingers up her ass and she came 3 more times. I was now fucking her so hard her fat ass titties were beet red frome slappin the side of the car. I couldn't hold back much longer so I said" Do you swallow bitch?"  "for you billy!"  She yelled. I pulled out and her tight beat up cunt slurpped pretty loud. I pulled her the rest of the way back in the car a positioned her for a good throat fucking.

 I rested her head on the door and grabbed for the roof. She opened her mouth and I plunged in full force. I fucked the hell out of the face just as i did her fat pussy. I was so turned on by all the spit flying around and how sloppy it sounded. I couldn't take nomore and unleashed the beast. Seven huge fucking hot loads of man juice right down her throat. She could'nt handle it all and gagged about half back up and spit it in the floor. As we drove back her new car now smelled of sweet pussy juice and cum. Hope the brother-in law dosen't drive it much I thought to myself.
