Tsukasa's too cute, and Rui can see how Tsukasa's belly swollen with his tentacle cock already, it's impossible not to get too excited. He can't wait to pump Tsukasa full of eggs, the blonde's insides are so warm and soft, and Tsukasa is so, so kind. He already showed Rui all the wonderful things human life has to offer, and Rui knows he wants to stay with Tsukasa, and for Tsukasa to teach their kids too how beautiful and calm their life can be. Humans are fascinating to Rui, but Tsukasa is way more special than anyone. He is so cute, how he moans and his eyes cry when taking Rui's cock, struggling to fit it inside him but also always so welcoming to let the alien inside... He tries to tell Rui to go slower with the eggs, but oh does he enjoy it when his insides get messed with, and how he can't help but moan when he moves, feeling so full of Rui... ughgjguhgu I get him...
