[SCPX-533] She always hangs out in my room reading manga on her own, and doesn't see me as a man, calling me a weak character... but my gal friend is curious about my big dick (Censored)

My gal friend usually hangs out in my room reading manga. To be honest, she saw me as a small-time character and didn't think of me as a guy at all. But then she suddenly noticed my big dick and became curious! As expected, she was trying to close the gap between us, and her goal was my big dick! The girl who used to hang out in my room to kill time got really into it and straddled my bare dick! Today is the anniversary of when my super-erotic female friend became crazy about my dick.
