A step sister asked her step brother to teach her how to deep throat without anyone knowing - Lovessie

A very sweet girl found a new boyfriend, but it turned out he loved deep throating. But... She'd never been good at it and didn't want to embarrass herself in front of her boyfriend. So she asked her stepbrother, who has a long dick (she'd accidentally seen his dick in the shower one day when no one was home), to fuck her deep, deep, in the mouth, right down her throat, so she'd get used to big cocks and then be able to please her boyfriend whenever he wanted. Her stepbrother had always dreamed of shoving his dick into his stepsister's mouth, so he happily complied.
