My step-sister use to tell me " bimbo sluts can't get decent guts " so i decided revenge on her by stealing her BOYFRIEND, so while my step-sister is out the bimbo would sneak into the guys bedroom while the girlfriend is out, and start by feeling herself all over in front of the guy and then proceed to seduce him with dirty talk then suck him off before riding him, talking about how even bimbo girls can still get nice guys, before encouraging him to explode inside her. The bimbo would seal the deal with a creampie from the guy and it'd end with the step-sister possibly on her way as she heard something.
