Yes

Ash walked over to Mewtwo, who instantly turned his head to avoid eye contact, also so Ash couldn't see his blush. 'Why are you interested in me?' He asked, trying to remain stoic, and failing spectacularly.

"You're in love with me too, you know. You appreciated my sacrifice back then, so I want to make a permanent sacrifice so we can both feel complete." Ash said as he kissed Mewtwo in the cheek, his clothes falling off.

Ash's member shrunk into nothingness, as his crotch began to grow out behind her into a long tail as her pink vagina surfaced, causing her to moan in pleasure and Mewtwo to become erect. Ashlynn's nipples puffed out into D Cup breasts, which led Mewtwo to enter a sexual fantasy he had never felt before. Was this what love felt like? He always wanted to feel it.

The pleasure skyrocketed for both of them as Ashlynn threw herself onto Mewtwo, grinding her slit against his penis as her skin became purplish-white, kissing him on the lips with all she could.

Arceus couldn't take this anymore, and teleported them to New Island, wishing to not see their mating ritual. It was already too late, as his golden penis was fully extended for all to see. He looked to Palkia, who was beginning to massage her cunt. "C-come with me, Palkia." He said as they went to the next room, where the rest of the legendaries could hear intense love-making sounds.

Ashlynn finally got her new mate's dick into her pussy when they got to New Island, and was already feeling the most pleasure she had ever felt in her life. "Mewtwo, do you love me?" She asked, as her feet and hands shifted and a tube like appendage extended from her head to the top of her back.

Mewtwo looked into his new lover's bright pink eyes and rammed himself into her hymen, breaking it and cumming, filling her with all the information she needed to have. "Yes, I do, Ashlynn." Mewtwo said as he kissed the now fully transformed female pink Mewtwo.
