Too bad there is no backstory, why the neighbor was on the table, why he was so hard to punish her, though it is understandable - without a reason to put in the anus with a full run, few will put in. She deserved it. Or is it a neighborhood game? Like, you poured water all over my apartment, and I'll pour sperm in your asshole. This version I like more, and then everything looks different - not enough he gave her, for such a need much more!
While the blond was polishing his prick, he was actively threading her asshole - he did not leave her anus alone for a second, kept rubbing it, and checking its permeability with his finger. In the end he got what he wanted!
