I think the boy getting jacked off has some mental developmental disabilities. Perhaps for his safety he can't be left alone, and 'Superboy' is someone who comes over to his house and sits with him at times. Or he may even be the boy's younger brother. I think the older boy is minimally-verbal, too, but he sure enjoys a nice handjob and orgasm! In this vid he never touches his own penis, so maybe he's not even capable of masturbating himself. So the only time he can enjoy this is when his friend with him and they're alone. Thus, the HUGE cumshot.
