Mom's finally home from work. She sits down on the bed and beckons you closer. "Son, there's something I need to talk to you about... I'm, I'm so embarrassed." She looks away. What could possibly be the matter? "Well, ok. Here's what happened. I was trying to find my phone this morning before work and I noticed you left yours in the living room. I thought I could use it to call myself, only... well... when I unlocked it, it went right to a picture of your cock." She bites her lip. "It's just, well... I haven't been able to stop thinking about it all day. It's just so BIG... I'm sorry, no son should have to hear this from his mother. I just had to get it off my chest... it's been so long since I've been fucked. What do you think we should do?"
You notice her staring at your growing bulge, the way her tits are fit to burst through her blouse... will you give Mommy that big cock she craves so badly? Mom gets an evil glint in her eye as she catches your eye. "There's only one thing: if we do this, you can't cum inside me."
