Step-Mommy is tired of catching you stroking your cock. She thinks it's time you had your first blow job. She takes her time getting you accustomed to having your eager young cock in her mouth. She doesn't want you to cum so quick so she gently licks your shaft up and down, kissing and rubbing her lips gently on your throbbing cock. Then she sucks your dick with increased pressure and making you cum so hard in her mouth.
