I enjoy masturbating my mature, greasy, fully erect, circumcised penis to this informative and educational film. I like how well-timed the music is, reaching a crescendo as the masturbating male achieves orgasm and ejaculates his potent, youthful seed. I often wonder what he could be fantasizing about as he is stroking his rigid, circumcised, unlubricated penis up and down. His eyes are closed for the entirety of the film. I really like the smile this young male has on his face at the end. It's a look of pure, post-ejaculatory bliss. With each viewing, I also like to take note the 1970's furnishings in the room. Since the young male did not appear to spew very much semen from his penis, the sofa was not in any significant danger of stray splatterage. (Yes, I made the word up.) Perhaps he was instructed to rub one out prior to filming. Lol.
