Kimi wa Ore no Tsuma ni Naru no Dakara

Alice is engaged to Reiji, the executive secretary of the Cunningham Hotel Tokyo. She always tells him how much she loves him, but he still treats her coldly. He teases her with passionate kisses, and she can't resist begging him for more....... "The more you cry out, the better you'll feel." With a confident, sexy smile, he caresses her lewdly, making her feel like she's about to drown in pleasure. An eager and devoted young lady is loved by a mature man, and this is her doting diary until their marriage!
