I think they are acquainted and are getting comfortable with it. I would be sooo nervous and reluctant but that's just me. I would like to believe that they are doing it for the first time. Fuck! I can't control my Urge to masturbate just thinking about how aware they are of their situation. Ohhh, naked bodies and legs crossing over. Deep breathing as each realize that climax is imminent. If their is a God I will spend a solid day with these two.
