My new stepsister, who I've just moved in with, is a socially awkward shut-in... She keeps conversations with her family to a minimum and just stays holed up in her room, engrossed in the internet. Naturally, I assumed she had no interest in me, but one day I found a note on the door that read, "I want to do it today..." It seems that despite being a shut-in, my stepsister has a strong sex drive, and masturbating to porn videos online isn't enough to satisfy her, so she wants me to put my dick inside her! That's what she's trying to say... Well, looking closer, she's cute, so I have no reason to refuse. From then on, whenever my stepsister gets horny, she summons me via note and we have sex every day. However, in everyday life, the distance between us remains the same as ever.
