My sister introduces me to her new boyfriend by having him over while she cooks dinner. I think he's really cute, so I can't resist teasing him a little. I love watching him squirm. I flash him my boobs, put my hand in his pants, and sneak under the table to suck him off right there in the kitchen. I get too bold, and she catches us! She's so angry she makes him fuck me really hard in front of her! I'd be embarrassed, but I deserve it for being such a sneaky little slut
