Your sister Yang (Futa)
From Create Your Own Story
Your sister opens the bathroom door and lifts the seat to the toilet, whipping out her large cock and letting out a stream of piss into it. She soon fimishes and strips, planning to join whoever is in the shower. She steps in behind you, but you cannot see who it is as there is still shampoo in your eyes. You wipe your eyes clear and open them just in time for your older sister to wrap her arms around your waist and start to grope your B-cup breasts, causing you to blush a deep red. "Good morning little sis." she whispers into your ear as she keeps squeezing your breasts, her erection poking against the small of your back, grinding between your ass cheeks. "Y-yang, what are you...?" You stammer out before gasping again from your sisters assult on your young, still developing breasts.
Do you:
Ask her to help you wash your back?
