18+ Fukushuu suru yori Mitsuai shitai: Wakeari Outaishi wa Hontou wa Tsuma ga Sukisugiru

Diana meets Crown Prince Astor for the first time and they marry. Their awaited wedding night comes to pass, but the following morning, his attitude turns icy. "Did I do something wrong?" When she desperately tries to win his affection and entice him every night, he suddenly transforms into a beast...? "It's your fault for being too attractive," he says as he persistently showers her with kisses and, over and over again, pours his hot semen into her depths. A bitter beginning turns into a life of sweet infatuation. A love story of palace newlyweds!
