It's an open secret that underground idols are connected to their fans, but I have one question. How can a girl who is young and cute enough to be an idol have a physical relationship with a weak man who is a fan? When I investigated, most of the cases were just trivial, such as having dinner. Among them, the one that caught my eye was a personal photo session. After all, being alone with her is a big deal. During one of these interviews, I met Yumerun-chan. She is a member of an underground idol group that consists of four people. Apparently, she has had photo sessions with fans, but there was nothing erotic about it and it was completely healthy. She didn't even seem to think that it was a connection. So I decided to actually have a photo session with her. Idols who dance and sing on stage are young girls, so they can't have no sexual desires. Although she says no, she exposes the inside of her costume, which she doesn't usually show, in front of the lens, and when an erect penis is thrust in front of her eyes, she only resists at first, but after a little teasing, she thrusts out her wet pussy and starts shaking her hips on her own. It seems that it was just a case of not being able to get the dick out at the important moment. There's no way that a girl who smiles and shows off her bare skin in front of her male fans doesn't have a higher than average sex drive. Her highly sensitive nipples become erect, she climaxes with convulsions, and she obediently accepts the creampie when the dick is inserted completely raw.
