Semen congestion - neighbour's stepson just pumps me full

It was another coincidence that the neighbour's stepson's shower was broken and he had to come to me... Unfortunately I hardly have time and I'm looking after the right thing, there he is, playing around with his cock, wanting to know from me if he has a horny part. Phew, that thing is really ** for his age... I suck on it briefly to get him to stop, but then he really wants to fuck me and plays around with my plump ass, getting really horny. Then he turns me around, fucks me hard like he must have learnt in porn and pumps his cum all over me. Wow, he had a lot of pressure... I just realised that I hadn't even noticed which hole he was actually pumping in all the back and forth. Oops...
