海の上で全裸オナニー!

I was jogging around the beach and decided to go swimming but Im so sweating! But! I didn't have any swimwear to walk into the sea... So while this early morning is nobody here, I just took off my running clothes and get into water absolutely naked! After nice swim, I back to my tent to get dry. But something is missing... My body wants some pleasure and I cannot say no while Im alone on the beach
