Funniest thing I've seen in a porno, many years ago. French porno, set during the Revolution. The Duke and the Count are having sex with the Duke's mistress, and the Duke comes in her mouth, her lips and chin showing some excess semen. The actor who played the Duke seemed to be a little bit airheaded and went deep into his role: he started to wax lyrical about his wonderful ejaculate which was now adorning his mistress--"taste it, cher comte!" The actor playing the count pales a bit. "Taste it?" The duke insists "Taste it, cher comte, taste it!"
The count's actor decides to take one for the f*cking team, and leans unhappily towards the mistress. The mistress' eyes light up with intense glee. Mouth full of jizz, she is the most blessed among sex workers, for she is going to have her revanche.
In one of the five famous most passionate (if not very pure) kisses, she gives the count a kiss with lips and tongue that absolutely gives him a proper taste of the duke's sperm.
