My son got married way too early. His mother and I tried to discourage him from marrying his high school sweetheart, before he had the opportunity to go to college and get a good job. But no, he had to marry his girl because he was afraid of losing the first girl he ever got to have sex with. His girlfriend was pleasing to the eye, and I could tell by the way she flirted with me that my son had his hand's full with that hot little number. I tried to tell him that there would be lots of pussy out there for him, and he didn't have to settle for the first one that had ever let him in. When he lost his job 6 months ago, we agreed to help them get started and that they would pay us back with interest. We were trying to teach them some responsibility. With neither of them working, they just seemed to keep getting deeper and deeper into debt. One day, his cute wife stopped by to talk to me while my wife wasn't home. She thanked me for helping them as much as we have, and said that she really wanted to repay us they needed more money for their car. She offered to wash dishes for me, or do gardening to pay back the loan, but I already have a wife and a gardener to do those things. "What would you like?" she asked. "Maybe you'd like to have something that we would have to keep a secret, between us". "We don't have to have sex or anything, maybe I could just jerk you off?" I was starting to sweat. I mean, here I was alone in my house, in my bedroom nevertheless, with my son's wife, and she was proposing to pay off the money I lent them by stroking my cock. What was I supposed to do? My brain was telling me to get the hell out of there... this was my daughter-in-law, but my cock was telling me something completely different. I let her lead me to the bed, and my brain shut off. The cock won. She opened my pants and pulled them down, while taking my already hard cock in her palm. She spit on it, leaving a long string of saliva leading from the tip of my dick to her plush lips. My hard cock was right against my son's wife's lips, and she teased me by denying me entrance. I couldn't believe what a slut my son married! She told me that she's always had a thing for older men, and asked if she could call me Daddy. She has always called me Dad, even before she married my son. She took off her top to reveal a pair of soft C cup tits. "I bet you'd like to see the pussy that your son gets to fuck all the time", she said as she fingered herself while stroking my cock. "I bet you'd like to feel that pussy, wouldn't you". She turned around on the bed and wiggled her round plump ass. She pressed her self back against my cock and let me fuck the crack of her ass. I was only millimeters away from her juicy pussy. She grabbed my cock in her hand and slapped it against her pink lips. She slid the head up and down the cleft and almost let me put it inside. I was almost fucking the same pussy that my son fucks! She stroked my cock with her ass up, reaching under her leg, so I got a nice long look at the wet snatch she denied me. She spun around and began to tease me with her mouth. Licking the shaft but not putting her mouth around and sucking me. She took my balls in her mouth and sucked as she stroked. The pre-cum was running out of my cock. My daughter-in-law was showing me what a good little whore she would be for me if I kept the money coming her way. She teased me by telling me how good her tight pussy would feel around my cock. "I can't wait for you to cum" she moaned. "I love stroking that fat fucking cock for you, Daddy". Finally I couldn't take it any longer. When she said "Cum for me Daddy", I let a huge load burst out of my cock and all over her hand. She licked the cum off of the head of my cock and told me how good it tasted. "Remember, this is our little secret", she said. "Can I go ahead and get that money for my new shoes, please?", she asked as she spread the cum around her fingers. What was I going to say now, no? My son's wife owned both of our cocks now. Starring: Sierra Sanders
