His hand gets stuck and he takes the opportunity to fuck
A story where a girl finds herself in a very big problem that she herself cannot solve and then a man just like she imagined appears to get her out of the mess, is a story that is constantly repeated throughout the history of the world. And this slut, although lacking in imagination, is a very hot little whore. Something that this guy takes advantage of to put his cock in her while she is in the right position to fuck him. It seems that her pussy was so eager that it blocked her brain and brought it to the point of ridicule. The same point necessary for any successful slut.
