The new routine [Humiliation]

This is part 5 of the story of my wife (33) opening up to having a new boyfriend (30). The other parts are posted here: part 1, part 2, part 3, and part 4. 

Friday finally arrived. The excitement wasn't just because the weekend was near, but because A (my wife's coworker) would be coming over and staying the night. As regulars, we logged in to work from home. I had a few meetings lined up and was busy on calls. During the day, R (my wife) told me he would be coming over sometime during mid afternoon. I asked her what their plan was, to which she just said that we would be going out for the evening and that's all.

A arrived just around 4 pm. I was on a call, so R went to open the door. As soon as he entered, he greeted her with a hug and a kiss on the cheek and then came to greet me. He had brought over a bottle of wine for later that night. As I was in the middle of a call, I wasn't able to talk much, so he went and joined R on the couch. I guess they still had some pending work, and they got busy with that. It wasn't anything different, just regular office & work discussion.

Once we were done with work, I asked him what the plan was for the evening, to which he said we were going out bowling followed by dinner. We got ready and left for the nearby mall, which also had a bowling alley. We enjoyed the evening just like regular friends. After finishing the game, on our way out, we did some shopping as well. When we reached the car, since I was driving, I got into the driver's seat. But R, instead of getting onto the seat next to me, just winked at me and kept the bags on the passenger seat and got on behind with him. During the drive to the restaurant, I occasionally glanced to see if they were up to something, but nothing seemed different, though they were sitting close to each other. At the restaurant too, she chose to sit down a bit far from me, closer to him. I had a feeling then might be up to something, so I just dropped my fork accidentally to glance under the table. When I bent down to pick up the fork, I saw that A had his hands on her thigh over the long skirt she had on and was gently caressing it. The restaurant was a bit dimly lit, so unless anyone was specifically looking, one will not notice what they are up to. But she was fully aware of what was on and let him do it. This was a new side to her, which I had not before.

After dinner, we decided to head back, as we had a bottle of wine waiting to be opened. Reaching home, I went to get the wine. When I returned, I found them in a liplock on the couch in front of the TV. It was a surprise, but I was expecting it because, isn't that why he had decided to spend the night over at our place? With a cheeky grin, my wife took the glasses from me, offering one to him. She excused herself to go get changed. This led to an awkward silence between me and A. He broke the silence by saying, "Thank you for having me over. Hope you don't mind if I spend the weekend here as well." I responded by saying that he is welcome to stick around as long as he wishes to. Not just because he was a guest, but also because I wanted to get in on some action about which I had been hearing for so long.

R soon joined us wearing new white pyjamas and a matching loose camisole. I could see that she was feeling shy but still came and sat down between us. It wasn't hard for both of us to miss her erect nipples pressing against the fabric. She picked up her wine glass and, after a sip, asked me to go get some snacks to have with the wine. I didn't want to, but I had to head to the kitchen to get some food for us. I was almost ready and was about to return when I heard a door close. I came back to see they had gone inside the guest bedroom and closed the door, leaving her camisole lying on the couch. Keeping the snacks on the table, I put my ears against the door to try and listen to what was going on. Insitially I couldn't hear anything, but soon I could hear soft, wet sounds that sounded like wet kisses.

I reduced the TV volume so I could hear better. Undoing my jeans, I had to pull out my hard cock to masturbate while wild thoughts started going through my head about what might be going on inside. All I could hear was her soft voice occasionally telling him to be gentle and go slow, followed by her moans. The intensity kept varying, but never too loud to be heard clearly from outside. I held back as long as I could, but was soon cumming. I hurriedly picked up the tissues from the table to stop from creating a mess there. But the sounds from behind the door were still on. I went back to the couch to keep myself distracted, not able to focus on the TV that was just playing. After almost an hour or so, R stepped out wearing just a towel around her. Her hair was a mess, and she was a little sweaty. She had come out to grab a bottle of water and pick up her camisole. She hugged me and thanked me for letting him stay over and told me to go to sleep and not to wait for her. Saying this, she went back inside and closed the door again.

I waited for some more time in front of the TV and then decided to go to bed. I turned off the TV and the lights, and on my way back, I again put my ear to the door to hear what was going on, but I couldn't make out anything. I left and, after a quick change of clothes, got into bed. I was hard again and hard to masturbate myself to sleep.
