The instructor had finger fucked her to two orgasms, shoved her panties and leotard deep into her slit, and then she sent her home to me. I would have...to thank her someday. Then I filled my wife’s pussy with my potent baby seeds. I was already looking forward to her next lesson. I would be looking forward to Tuesdays and Thursdays for the next ten weeks.On Thursday I watched my wife take a bath and nurse our daughter at the same time. Then as she got dressed she asked me if she needed to wear. "We're you masturbating? It's perfectly normal for boys to do that right? So you didn't do anything wrong." She said. Her face was red and I could tell by the look in her eyes that she saw most of what I did. "I heard the sound of your laptop and I thought you were chocking so I came to see." Her words made it official that she saw me right from the sex scene."It's ok. Thanks for being so concerned." I told her. Thinking she might leave if I thank her."Are you gonna do it again? Masturbating?". " "Good luck," Zeez tells me as he walks away. The driller was barking out orders and the men scrambled to do what he wanted, me included. I did my best, I didn't screw anything up or cause any safety problems. There were no breaks, you run behind the rig to take a leak. You better make sure you take a crap before you come out here, there just isn't any time for that. All I had all day was water and plenty of that. Just before sundown the next crew came out and took over from us. I couldn't be. I stuck out one of my hands to go touch it and she pushed it back against the wall telling me "not yet".Next she turned around and unzipped her jeans. Her thong was already revealed slightly, but next thing I know she is bending over and her amazing ass was slowly popping out inch by inch out of her denim jeans. It looked so tender and firm and although I was taken away by her tits I really wanted to leave a hand print on her ass. I know she told me "no" to the touching before but I couldnt.
