Hikaru, who works at the library and has a bright personality, encounters Mitto and Monaka, a noisy lesbian couple, on the train after work. Seeing Hikaru reading a book, Mitto and Monaka instantly fall for her, exclaiming, 'Damn! That kid is so cute!' The two tried to lure Hikari into lesbianism, groping each other's breasts and engaging in heavy kissing right in front of her. Unaware of Mito and Monaka's seduction tactics, Hikari scolded, "You can't do that kind of thing on a train!"

However, as they got caught up in their girl talk, Hikaru started feeling uneasy about Mito and Monaka's increasing physical contact with her... The two's actions escalated, pinching Hikaru's thighs from both sides with a W-crab hold, then reaching their fingertips towards the exposed genitals... Hikaru couldn't hide his bewilderment, but was developed into a lesbian by Mito and Monaka's crab claw technique, looking forward to meeting the two on the train after work...
