You need to give her a little more persuasion first...

Stepping closer, you back your mother against the wall of the shower. Leaning down, you take one of her nipples into your mouth. "OOOHHHH!" She moans as you start the teasing process.

"P-pleasseeeee..." "Please what?" "D-don't s-stop!" With the knowledge that your mother has fallen victim to your seduction, you press on, kissing your way lower and lower until you eventually reach your goal. Finding yourself face to face with the pussy that you came from, you lean in and take a sniff of your mothers pussy scent before you reach out with your tongue and start licking your mothers pussy out.

Feeling her legs start to buckle under her as her orgasm hits her, you steady her with your arms. After another five minutes of eating your mothers delicious pussy out, you decide that the time is ripe for you to fuck her brains out.
