Sex ed lesson with step mommy

You walk into step Mommy's office and she's working. You tell her about your sexual education class that you took today. She gets excited and begins to ask you how it was, but you are still unsure about somethings. You've never seen a vagina in person before and aren't quite sure what one looks like. Step Mommy explains that not all bodies are the same and invites you to sit down. She wants to give you the, 'hands-on,' lesson with her on body. You points out her full, brown breasts while taking off her bra. Giving you permission to touch them, you feel how squishy and huge they feel in your hands. You want to suck on them. You want to see how they feel in your warm, wet mouth, but Step-Mommy says she has something else for you. She grabs your hand and places it on her vagina.
