Wanker goes too far by touching my pussy

One hot summer day last year I was feeling a bit horny and decided to go to the beach to enjoy being alone and nude in the sun.

I walked quite far to a part of the beach where I couldn’t see any people.
I brought two hidden cameras since I like to shade my face from the sun and it’s fun to watch afterwards if there have been any peeping Toms’ sneaking around.
It will later show that this time it was very fortunate that I set up the cameras.

I rub my body with oil and after a while I can’t resist but to slowly start fingering myself.
I had covered my face using a t-shirt and with music in my ear plugs I couldn’t see or hear anything around me.
I was getting more and more exited and I knew I just had to go on until I reach an orgasm.
It’s hard to describe but it’s such a liberating feeling to be outdoors naked and maybe the thought that someone can see you add that extra spice.

My excitement came to an abrupt end when I felt something between my legs.
I thought it was a bug that bet me so I jumped and pulled the t-shirt off my face.

I was very surprised to see a naked man and I realized he was the one who touched me.
The top of his cock was covered by cum and he was still hard.
I just said “What the hell are you doing?” and he went on “I’m sorry”, “I’m stupid” when he walked away.

When watching the videos afterward I could see he had taken quite a few turns around me before the approach and even shot a load of cum.

After a while I calmed down and continued to play with my pussy but I couldn’t relax enough to come to an end.

So guys, what is your take on this?

Is it OK to touch a woman without her consent (I was obviously not aware of him standing near me) or was it my fault acting (sexually) the way I did?

I bet some of you will say I’d let him fuck me but sorry that is not how I work.
First there must be some chemistry and attraction before I take that step.

I would like to hear your opinions though.
