Surprise Trans step sister

Your dad is a cool guy so you can't believe that he married a old hag. She a mean cruel woman however she has one saving grace, her daughter Ashley. Ashley is a cute redhead girl. Even though she's now your step sister you can't help but fantasize about her and how tight her pussy is.

You can't help but give her looks as she walks by. However sometimes you think you see her looking back, but it could just be a reach. Maybe she thinks your weird. Ashley seems cool with you though. You both play videogames and Magic all the time. She laughs at all your jokes even the bad ones and sometimes she'll touch your shoulder a few to many times. Not that you mind.

Then your dad says that him and the hag are leaving the state for their honeymoon. For some reason it's week long one. You zone out on the rest of the details he tells you because all you can think about is having that time with Ashley. Just the two of you alone. It'll be the perfect opportunity to make a move.

The day comes when they leave and you decide to go to the liquor store. Maybe some booze will help the process. You make your way back home. By the time your back the sun is setting It looks like Ashley isn't home so you go up to your room.

But weirdly your door is cracked open and your light is on. You walk up to the door and peek inside. You see Ashley with a pair of your dirty boxers stuffed in her face. She looks like she's masterbating. You look down and are shocked by what you see. She jerking off a dick! Ashley has a dick! It's small couldn't be bigger than 4 inches. Not only that but she's jerking off over a clean pair of boxers. Does she want to cum on them and put them back?

Your head spins. You have to hand it to her you could have never guessed that she was transgender. She was just so beautiful. Then Ashley picks up the pace and you notice precum on her cock and she drags it on your clean underwear while jerking.
