“Don’t hold back... I want to hear you cry out” His large and gentle hands lure me into a doze in the darkness. His fingers stir around in my nether regions that are so embarrassingly wet! Was my beloved senior Shibasawa always this dirty!? Tamaki is a teacher who is reunited at her assigned high school with Shibasawa, the boy she had had a crush on. His unchanged kindness makes her heart flutter, but she has her own “reason” for being unable to take the next step... Then one day the two of them end up shut inside the pitch black warehouse of the gymnasium and they accidentally kiss! Their kiss grows deeper and deeper and soon their tongues are intertwined. My dear senior, tell me what this kiss truly means...!
