TIFU by shocking the penis-head of my Fiancé.

I don't know why, but I felt the need to share..

Today I (F25) was laying in our guest bedroom/office while my fiancé (M29) was working from home at the desk. I normally try to leave him alone, but there are many times throughout the day where we goose each other for laughs. Well.. he took a break from work today and decided to pull his dick out and thought it would be funny if he started to a 'helicockpter' next to the bed. Naturally I went to put my mouth on it and when I did, there was an audible snap and I felt a shock on my mouth! My fiancé fell back into his chair and yelled, "You shocked my dick!!" He had socks on so I think when he was shaking his dick around next to me, he was building up a static charge? We ended up just laughing it off.. but I kinda feel bad.

TL;DR Went to put my mouth on fiancé's penis-head, static electricity got in the way.
