In a viral video that has racked up more than 35,000 views, he gestures toward the sun as three naked men lie down, point their backsides to the sky and make sounds of pleasure.You can read more about this in the New York Post.
“[Thirty] seconds of direct sunlight injection to the anal orifice is equivalent to being outside in the sun all day!”
