We have been married about three years and i work 60 hours a week so i spend a lot of time sleeping. Shelly was a nice looking woman and had gotten tit implants at 18 so she had some nice tits. She is 5 foot tall with a pretty peteat body. our sex was pretty decent but shelly wanted more than i could give. She kept telling me if i didnt get better she was going to fuck somebody else. I thought she was kidding so i ignored her. Well the next month or so i would come home and she would be in her panties and bra which really showed those tits and that turned me on but she didnt want to fuck. I thought it a little strange so one day i came home an hour early and walked in on her fucking a big black man . I got inraged and told him to get the hell out but shelly told me to shut up and sit down. As i sat down he continued to fuck her and then i noticed his dick was at least a foot long and really big around. He was drawing his dick way out and shoving it back in. Shelly was shaking all over the bed. He had cum all over his cock and all of a sudden he stopped and i could see cum ozzing out from around his cock as he filled shelly up with his cum. He pulled out and took the sheet on the bed to wipe his cock. He said he was going to get another beer and walked by me and smiled. Shelly called me over to bed and i thought i was going to get some pussy but she told me to suck his cum out of her pussy but i said no but she just pulled my head down to her pussy so i did it .
