Hsing/Seth the Lucario was the first one to reveal his desire to Aurélien and make him discover sex with Pokémon, even if Hsing only gave him fellatio, it was enough to trigger this desire. This contrasted with Zener, the Alakazam, who accepted Aurélien's advances and allowed himself to be fellated by his trainer, who was also his first time as an Alakazam. From then on, Aurélien often had sex with his Pokémon, especially Hsing, from anal to 69 with Lucario.
However, Aurélien never tried anything with Ambre, as he knew she was in a relationship with Drake the Dragonite. This didn't stop Drake from hearing about his trainer's little séance with Zener/Hsing and coming to Aurélien to tell him that Ambre would be very happy to be taken by his trainer.
As Ambre was Aurélien's very first Pokemon and he was very confident, it was a very special offer and he decided to take the chance. Drake even helped organise the event by waiting for Arcanine's birthday (which was also Aurélien's).
