Suggest her to give you a bath
From Create Your Own Story
"Hey sis, could you give me a bath?"
You ask trying to sound as childish as possible meanwhile you thought heavily on the phrase "It's fine, he's still a child" while looking at her. As expected your sister looks surprised at you but quickly calms down.
"Oh, sure."
You help her get undressed and as you do you get to see her naked body. As you had already notice, her small breasts leave much to desire. You also get to look at her crouch, a nice and smooth slip with a small busch over it. Your hard on pulsates in excitement. You have decided, you will not leave the shower until you cum.
"Are you alright? That looks like it hurts."
You grin and tell her that it's fine. You both move inside the bathtub and turn the water on. Picking up on the soap your sister moves close to you and start to scrub your body. Since you are smaler than her, she's on her knees in front of you scrubbing your torso right now.
"Hey, you still haven't told me what that is... S-since it's in your crouch could that be your penis?"
You nod at her as you notice that she's really doing her best to avoid that area. You can hear an audible *glup* coming from your sister. You realize that now's the perfect time to influence her mind.
What thought do you send at her:
