You decide to rush down the stairs

You decide you need to worship her feet right away you cant risk that thing entering your bladder. Still holding her clothes in your hands you run down the stairs yelling " Rachel stop wait right there!" Getting down the the stair you drol her clothes and get to your knees. Bending over you kiss her toes peeking out of her pleaser heels. Looking closer as you kiss her feet you can help but notice the sticky white fluid on her shoes. Realizing its cum as your still kissing her foot you look up at her face seeing her standing above you with a large grin on her face she says "wow if i knew you wanted to lick cum off my feet before step bro i would've let you! This guy I've been seeing loves finishing on my feet and making me go home with the cum still there. Also why do you look so cute i dont remeber you looking this feminine or i would've turned you into my sissy **** long ago". Looking down at you she notices her lingerie on the floor behind you getting angier she shouts "were you snooping in my clothes loser" as she grabs your baggy hoodie making it slip off your slender body exposing your massive tits. Shocked by the sight she laughs and says "well what did you do now loser did you want to be a sissy fuck doll so much you got tits" as she bends down and grabs one of you nipples pulling on it as you moan out and cum in your pants.

Looking down at you and hearing you moan she quickly realizes they aren't fake tits in fact they felt as natual as hers. Looking down in shock and realizing her step brother is now her step sister she smiles wider bending down she grabs you by the waist and pulls you up. Grabbing her panties off the floor she wraps them around your wrists imobilizing your hands and wrist. Grabbing the panties and your hands with her bra in the other hand she pull you up to her room and throws you on the bed.
