To masturbate him (english)

The giant bag released the pressure he was exerting on your little body and asked you to masturbate him with your whole body.

You are **** to this idea when you see the state of his cock and the foul smell resembling that of the sewers which escapes but having no real choice you decide to carry out these words.

You slowly approach the huge cock in front of you. Once in front of you realize that this dick is a head taller than you and that the smell is even stronger which makes you want to vomit. Despite this, you grab the dick with your arms, thinking that this is the best thing to do and you begin to move back and forth up and down for the pleasure of the giant, who begins to let out small moans of pleasure.
