Step-sisters New Nighttime Routine

Your ditsy step-sister gleefully comes into your room excited to tell you about her new nighttime routine. She starts off by showing you the stretches she's been doing, seemingly oblivious to the fact that she isn't wearing pants and is flaunting her ass and pussy right in your face. She moves on the the second step of her new routine and moisturizes her inner thighs and pussy, asking if you want to touch her and feel how soft she is. She notices that your skin is dry and offers to put lotion on you. You agree and she starts putting lotion on your penis, she keeps noticing dry skin so she continues rubbing you down there until you accidently cum all over her face and tits. She's shocked and confused, saying "but... I was just showing you my nighttime routine", she apologizes and says she probably went over board before telling you she hopes you have a good night.
