Horny professor teaches double insemination

OMG! That was the hottest double insemination of the year ever! And completely unexpected. On the side, I give private lessons in biology. Today I had a house call with a nice man who is doing his A-levels. He wanted to know if double insemination makes sense in terms of evolutionary biology! And since I want 100% satisfied customers, I showed him on the living object how evolutionarily meaningful such a double insemination can be in nature. First I just grabbed his cock out of his pants and made him nice and hard, then I want to be fucked..unfortunately he was so nervous that he came quickly and squirted everything into my cunt. All the sauce dripped out of my cunt and he smeared his dirty cock clean on my asshole. That only made me even hornier. And now I wanted to feel his cock in my ass too. Again and again he rammed his thick part into my ass cunt. While the sauce was still running down my cunt, he was already squirting the second monster load into my tight ass. Every time he puts his cock back in, he pulls the hot cum-mud sauce out of my ass. What a horny anal mud slide! I love it!
