It was going to be a great day. I was coming home a few days early from my deployment overseas and was ready to see my wife again. Since we were coming home a few days early I wanted it to be a surprise. I got an uber from base to the house ready to get home and be with my wife, it had been a long nine months. When we pulled up I was confused when there was a Toytoa Tacoma parked in the driveway next to my car. I got my stuff out of the Uber and started up to the front door, still trying to figure out whose truck that was. As I walked by I noticed an Army hat in the front seat. My stomach dropped. I stood there for a few minutes trying to figure out what to do. I decided to sneak around the back and try to see what I was about to walk into. As I rounded the corner, in the back, I noticed our bedroom window blinds were open. I crouched and peaked in. What I saw stunned me. My wife. Riding a jacked guy. I sat there and watched, confused and not sure what to think. I saw her straddling him. Small saggy mom tits bouncing up and down. Head thrown back in ecstasy. As I watched, the last nine months caught up to me and I got really hard. I couldn’t help but to sit there and watch her hips sway and him grab her tits as they bounced. Suddenly she climbed off and I saw what he was working with (way more then me) and she took him all in her mouth. It only took a few pumps in her mouth and I could tell he released in there (something she never lets me do). He got up went to the bathroom got dressed and gave her a kiss and walked out. She just laid there. Never getting up the whole time. I heard his truck start and back out. I figured I couldn’t sit out here forever so I went around used my key and walked in. I heard my wife from the other room say, “what’d you forget?” I walked straight back there and saw her on the bed, naked, fingering herself. She was so startled she screamed got up and ran to hug me. She must’ve been so excited to see me that she forgot that her boyfriend just came in her mouth because she kissed me and I could taste it. I asked her why she said what she said and she turned red and tried changing the subject. I told her about how we got an earlier flight and I was trying to surprise her. She, still naked, took me over to the bed and stripped off my uniform, saying that she had been waiting nine months to feel a cock in her mouth and pussy. I had never heard her talk like that. One thing we had always been into was tying each other up so I told her I wanted to tie her up and have my way with her, she agreed. I tied her up on her back so I could watch her tits bounce while I fucked her. Right before I came, which didn’t take long, I pulled out and as I walked around to her mouth I told her that I saw what she had done. As she tried to deny it I put my cock in her mouth and started in and out. I told her that if she was going to have a boyfriend that’s fine but I get to use her like he does. She moaned an “Uhhuh” and that’s all it took for me to release nine months of build up. After untying and cleaning up we decided what was allowed and what was not.
