Hello everyone, my name is Senou Koyuki. I'm a little over 150 cm tall, with thin, short hair, and my chest measures 76 cm, making it quite small. However, my nipples are surprisingly well-developed and highly sensitive. Because of this, not wearing a bra causes constant friction when I wear shirts, which can be embarrassing. People often say, "Your breasts are underdeveloped," but in fact, my nipples are fully developed and hold their own unique appeal. Let me honestly share my everyday experiences with you. Please take care of me.
