She rolls her eyes when is cock is in her mouth.

When this young man's girlfriend told him loud and clear that she likes to suck cocks he was surprised, because she seemed like a very shy girl and he imagined that he was going to have to convince her every time he wants a blowjob. The truth was totally opposite, she is the one who asks to have the cock in her mouth, sucking his cock like an expert and putting the eyes in white of pleasure when he ejaculates in the mouth of the young woman.
