Mama

You and their girlfriend are walking towards her house. It was finally time for You to meet their girlfriend's parents and he was nervous, I mean meeting someone's parents is obviously a very big deal! "Don't make such a big fuss about meeting my parents! We're just going to have a meal together!" You's girlfriend chuckles softly "You're really a scaredy cat~ my mama isn't so strict, okay?" You ask about her father and she reassures you "Papa's away at work! Can you relax now?" You two get to the the front door of her home, You's girlfriend calls out to her mother "Mama I'm home" "Welcome home~" An extremely well-endowed woman was in the doorway, this was your girlfriend's mother "You came earlier than expected…" She said sultrily, clearly given You a once over Her tits were HUGE and you couldn't help but stare slightly, your girlfriend looks at you strangely "What's the hold up?" Her mother chuckles seductively "Ah! That's right, come on in~" The three enter the home and Mama blushes slightly with embarrassment "Oh! I forgot to buy some things for dinner…" She turns to her daughter "Sorry, could you run an errand for me?" With a huff, her daughter agrees "Aw, fine I'll go" As she leaves, you and Mama sit down parallel to each other on couches in the living room "I didn't know her boyfriend would be so handsome" she says towards you as you deny this modestly "Hmm? You're so modest!" She says with a flirtatious smile "I'm sure you're popular~" You again deny this, but you can't help but get a good look at her assets once again She notices your gaze and strikes an lewd expression, clearly pleased by how this is going "You know… since just now, you've been staring at me with quite a lecherous gaze" You vehemently deny this, but she simply chuckles as you do, retorting "You just glanced at me again, even as you deny it~" "How do you think my daughter would react if she found out? I didn't know that daughter's boyfriend was a pervert who gets turned on by his girlfriend's mother~" She teased as you deny the fact that you're aroused at all, begging her to believe you "Oh yeah?" She says, with another teasing tone "Then… prove it" She leans forward, giving you a generous view of her chest "It's simple, all you have to do is stand up!" She says, her face getting closer to yours "Stand up with your back as straight as a pin, it'll be obvious whether or not you're aroused by me then…" He face was now inches away from yours, he face painted with pure lust and excitement "…so go on stand up stand up at once"
