Gokujou Ouji, Unmei no Tsugai wo Hirou

Chased by slavers, Charuelle jumps into a random passing carriage as her last hope. The owner of the carriage, with his bewitching face and muscular body, was Modestro, the prince of the kingdom! Thanks to his protection, she was able to escape her pursuers, but Charuelle has another problem.......

"I'm in heat for the first time... I'm in pain... help me!"

Modestro's long fingers precisely stimulate her erotic zones, as the pleasure overwhelms her rational mind. Wanting more, Charuelle rubs her twitching body against the prince's lower body. A masterpiece of historical Omegaverse between a low-class heroine in heat and a reclusive prince hungry for love!
