Wanting to see my wife get fucked by strangers

Thinking of my wife getting fucked infront of me turns me on.

Real incident
Hi, I (33) was once travelling with my wife(30) and stayed in Cochin. She had a 3 day work seminar. It was a ok ok hotel. Not very lavish or something. Had a working AC and TV so it was good. Since it was not a chain hotel, it was operated a little less professionally. Like you have to call for room service else they will not come, no uniform etc. But since it was near my wife's head office, we stayed there.
On the very first day, when my wife left after shower I was making space for myself on the bed by removing her house clothes from bed which she had thrown and left. I placed her t-shirt and lower on the table. Then I went to the bathroom to brush. I saw her bra and panty on hooks on the bathroom door. It was a lacy green panty, and wet and clean, with her black bra. She was 32 D so it was a huge bra. My dick was already hard. So a thought into my mind I took the bra and panty out and laid them on the table sides to dry. Then I called the room service. I wanted to see how the room service will react to see my wife's chaddi and bra.

He (around 40) came, I opened the door and went in the bathroom with the door open to shave. I had kept eye on the guy through the mirror. He was sweeping the floor with broom. At first he didn't notice it. Then suddenly he lifted his head and saw the chaddi and bra. Then he immediately looked towards the bathroom door. I was pretending to shave with my back towards him. He touched the chaddi and smelled it. Then squeezed the bra. Then continued to clean. Then he did the same when he came to mop the floor. I was so hard.
The next when my wife getting ready and removed her used bra and chaddi, I told "You go and take shower, I will clean them and dry you are getting late anyway." She thanked me and left.
Now I had her used chaddi and bra. I called room service. And before he came I placed the chaddi and bra on the bed this time as if she just threw them there and left in hurry. I even place the condoms packet on the night stand.
He came, I pretended to be busy and opened the door and went in the bathroom and started to shave again. Still keeping an eye on him via mirror. He was looking for the chaddi and bra. He eyes lit up when he saw the used chaddi. He pretended he didn't see and started to sweep.
Then taking a glance at the bathroom door, he quickly picked up the chaddi and took a sniff of it. He was in heaven. He picked the bra and smelled it too. He kept smelling the chaddi again, with his one hand in his pyjama. Now since his back was towards me, I had now turned towards the room and was watching his sniff my wife's panties.
I think he suddenly realized that I too was in the room, he turned swiftly towards me. I couldn't turn that quickly and he caught me watching him with his dick out and my wife's chaddi to his face.
At first he was like "Sorry sir, Sorry, mai to... mai...."
Then he saw my hard dick poking in my shorts. He slowly came close to me and smiled.
"You like watching me fantasize about your wife. Don't you" He said by holding my dick. He was now incharge.
I was so in shock couldn't say a thing. He pulled my shorts down and looked at my hard small dick. He laughed and started to stroke it while looking me in the eyes. Then he tugged my balls to make me go down. Then he pushed my head down, making me go on my knees.
Then he placed his right hand behind the back of my head and pushed forward. He made me suck his dick. While with his left hand he was smelling my wife's used chaddi. He had closed his eyes.
He fucked me for a min or two then pulled his dick out and came on my face. He used my wife's chaddi to wipe my face and said "Now go and wash these"
I had already came on the floor.
He pulled his pyjama and underwear and looked at me and said, "I want you to keep her unwashed panties tomorrow as well. And one more thing I want you to make a video of her getting naked, getting out of her panties. "
I nodded. And I obeyed,
Next day he came as soon as my wife left. He closed the door and pushed me to bed. He took wife's chaddi and started to sniff them. Then he took the bra. "Put this bra on" He told me I did.
Then he asked for the video. I gave him my phone. Then he turned me around and bent me over the bed. He pulled my underwear down and place the phone on my back with the help of a pillow. Then he held the panties to his nose with one hand and held my waist with another Instructed me to spread my asshole with both hands. I did,

Then he applied some oil on his dick and started to insert his dick in my asshole. It was tight, Very tight. But he didn't stop. At last it went in. He was watching my wife naked in the video and fucking my asshole. Today he came prepared and fucked me for like 15 mins. Then he came on my back.
Then he fell on the bed. He stayed for a while watching more of my wife and mine sex videos we had taken. While I sucked his dick again. It was fun.
He told me to convince my wife to have sex with him but we were leaving the next day.
I told him I will come again and this time he could fuck her too.
