Tsubasa Hachino and Mika Kurosaki are former lovers. One day, when her cohabiting 'Tsubasa' girlfriend came home, she suddenly got a call from her ex-girlfriend 'Mika'. The two of them feel very awkward at Tsubasa's house, even though they are excited to meet again after a long time. Meanwhile, Tsubasa started by asking, "Would you like to stay?" She went out of control in the wake of the Berokisu that she had accidentally done, fingering from morning to night, repeating lesbian kisses, and a total record of three days of crazy and squishing.
