We pulled out from the beach and headed North on I-45. Around Houston on Beltway 8 to avoid city traffic and then we were on our way north on I-45. We... found a nice camp ground near 'Big D' and checked in for a couple of days. We hit all the high points in Dallas including Six Flags, Cowboys Stadium and a bunch of the touristy places.Back at the campground we had dinner and decided to rest for the evening in front of the satellite TV. At bed time Kim gave me that lost puppy look so Judy and I. He grunted and groaned as she cleaned him of the last bits of semen. With one last suck, she let him pop out of her mouth audibly and smiled, cum streaked and happy. “Who do you belong to?” he said, positioning her head up and keeping her locked in his hands. She smiled wider and answered, “I belong to you, Sir. Always.” He growled quietly and said, “Good girl. Rub the cum into your skin.” He released her and she began with a thumb across her coated eye. She did her best to recover as much. We used to shrug it away saying that we are just good friends.It all started on a fine Saturday when we went to watch the movie Lage Raho Munna Bhai. It was during the interval when we were casually joking and my hand fell in between her thighs. For some strange reason, I did not take my hand back from there neither did she try to push it away. The movie resumed and my hand still stayed there. I was thinking what to do and finally pushed it up a bit and felt some wetness from her pussy. She was. My wife then knelt behind me and started pressing her cock against my tight little hole. I was totally blown away – doggy style is one of her favorite positions, and I couldn’t count the times that I had fucked her like this, and now she was going to fuck me the same way. I asked her to stop teasing me and fill me with her cock. She told me I needed to tell her exactly what she should do. I begged her to fuck me like a cock hungry slut, to fill my ass with her hard cock. She started sliding it.
