Pervert ejaculates without touching his dick in front of three teenagers

This pervert is lying next to three teenagers and decides to get naked in front of them. They do not see it, but the man's dick begins to get hard and the girls are a little uncomfortable, but they get very curious and look at the dick every time, which gets bigger and harder. The dick beats and the man's breathing speeds up until he ejaculates without touching his dick. The girls can't explain how this is possible. They decide to leave but the man doesn't need them anymore.
