Hot Lady Hot Tub

We were put into a unit when I first moved to the city for work, it didn’t take long for us to see people always watching so I thought we’re going to give a show now and again, I used to fuck my wife so hard knowing that the lady on the same level as us could see everything.
One night I seen a couple fucking in the hot tub and I got an erection straight away.
I said to my wife I’m going down to get a closer look.
My wife said I think you should go and help her out, When I got there I already had my cock sticking straight out in front of me with no pants on. The lady looked straight at me and said to her friend look at this guy big cock.
I nearly froze until he said to her do you want him to join us?
She said yes so I sat on the side of the hot tub and she just started sucking me
, it wasn’t long and he stopped fucking her and she moved my way where I grabbed her arse and just drove my cock into her as hard as I could knowing my wife was watching.
She was going off just like what we heard and then seen before I came down all I could do was just give her my best, this went on for about 10 minutes before I said we need to get out of here or security will report us to the police. They were on the bottom floor so we went in there for awhile, maybe about another 10 minutes before I finish inside her and said I have to go.
She said I’m a flight attendant and I’ll be back next week if you want to join me again and gave me her number.
I took her number and departed back to our unit where my wife said I need you to fuck me like. Know you have done her.
I never did call her but my wife said just think about her when you’re fucking me, I cum so badly when I think about her.
