The guy first licked her thoroughly and fucked her with his tongue before shoving his aggregate into her asshole. The girl showed that she is an avid fan of anal sex, which she enjoys. She gives a blowjob too, doing just awesome, swallowing a big shaft up to her balls, in her deep throat. The guys got everything they wanted from each other.
What can I say - she did a great job! We had a couple of ladies in our group who thought that it was much easier to pay in kind to the professor than to be up all night cramming incomprehensible formulas and dates. But here, as they say, it is a matter of what you learn!
How do you live with a wife like that, you're a total moron.
