Watched by strangers while fucking my wife's ass

For the last couple of years my wife and I have been having sex outside in public places. Mostly it’s been in the evening after it’s gotten dark. We will usually go to a park after dark and find a secluded park bench or picnic table and fuck. As far as I know no one has ever seen us. Until recently we stayed mostly dressed so we could cover up quickly if we thought we might get caught.

Most recently we went to park that is a lot more crowded than the parks we usually go to. It was dark as usual but there we still few people around near the lighted areas of the park.

This park has some woods along one side, away from the lighted parts, with some trail entrances. We walked to that side of the park and found a bench near a trail entrances. We thought it would be safe there since we hadn’t seen anyone come out from trail since we got there.

We sat down and started playing with each other. She pulled my cock out and started stroking it. I put my hand up her dress and rubbed her clit and finger fucked her. My wife knelt between my legs and started sucking my cock and I reached around her and stuck a couple of fingers up her ass.

We eventually ended up with her sitting on my lap facing away from me with my dick up her ass grinding way.

Now my wife loves anal but she doesn’t cum from it and she loved to cum when my cock, or anything else is deep in her ass. So to make her come either she or I rub her clit or she use a vibrator.

On this occasion she reach down between her legs and slowly started rubbing clit. It just at this point with my wife grinding her ass on my cock and rubbing her clit that a couple walked out from the trail right in front of us. They were close enough that it was obvious what we were doing even though my wife still had her dress on.

They stayed there watching us but my wife’s eyes were closed so I don’t know if she knew they were watching us. I whispered in her ear that someone was watching. She quickly opened her eyes but didn’t stop grinding on my cock or rubbing her clit.

I whispered again that I wanted to take her dress off, she had nothing on underneath, and she gave me a slight nod. So I lifted her dress up over her head and threw it to the side. So now my wife is facing this couple completely naked with my cock up her ass and rubbing her clit. She closed her eyes again and started grinding my cock hard and furiously rubbing her clit. She came quick and hard right in front of this couple. I told her I was going to cum and she pulled off my cock and started stroking it until I came all over her stomach.

As soon as I finished cumming the couple hurried away, probably to go home and fuck.

My wife put her dress back on and we walked to our car. She told me how much she loved being watched and said she wanted to fuck in front of more people.
