Secret Crush

You have always had a secret crush on your hot step-sister Sophie. She is always lying around the house wearing skimpy dressing gowns that let her tits fall out with ease. She is your step-sister though so you need to play this cool and nonchalant. She wants to chill in your room, so in return, you should get something x-rated as a thankyou. Those supple breasts will do the trick.
