As for me the lady is not very pleased with this kind of sex! The expression on her face never showed that she liked it. I think she would have enjoyed it more if she had served the men one at a time. And the two of them just bore her. Did the lady enjoy herself? I don't think she did.
I must say the lady is very experienced - her front is developed to the limit! Too bad she sucks so little - she clearly does it professionally! When the cock falls into such an experienced mouth you want the lady to suck it to the peak and swallow the cum. And then, when your pleasure was just off the scale, she continued to suck his cock slowly and tightly! And then, after a little break, it's nice to put the lady in the cunt and slowly fuck her for a long time!
My sister is so talkative that if I were my brother, I would personally fill her mouth with sperm to keep her quiet for a minute.
