You ask your stepmom to have a friend over later in the evening. Your stepmom thinks it's a little too late, but you remind her that you're an adult now - you can do what you'd like. She checks herself, realized you make a good point, and agrees. As long as you're not too rowdy, have any girls over or parties, you should be ok. Later in the evening... You leave to go to the bathroom and come upon an interesting scene when you get back. You can't find your best friend, and when you go looking - he's in your mom's bedroom! Your Mommy has had a couple glasses of wine and is chatting with your best friend about how you've both grown up so much. You notice her robe is starting to fall off to reveal her BBW body in a tight tiny body suit. Upon pointing it out to her, she snaps at you using a dominant, patronizing tone, putting you in your place. She can do whatever she wants, she is your Mother after all. Out of the corner of your eye, you notice your best friends cock is hard. He's stiff from seeing your sexy Mommy flirt with him and put you down. Your Mom notices too - quickly taking the situation to her advance she asks you how it makes you feel. Scared? Intimidated? Turned on? She pulls out your friends big cock and flaunts it in front of you. It's ok if yours is much tinier - that's why your Mommy has your best friend to play with instead. She runs her long nails down his boner, leading to a handjob and eventually a blowjob. You love seeing your Mommy take your friends big dick down her throat. Soon she's making him cum in her mouth and over her tits - a load you could never produce. You're Mommy's Little Cuckold.
