Once he is close enough, you motion for him to be lifted right on to your deep, squishy, and gurgling coils, putting even more weight on your rival-turned-seat-cushion below you. Your weight and the shiny Arbok's sags into the plush seat you are on, half-crushing the humiliated serperior below you two.
The Arbok blushes and squirms, your smooth, green body pressing into his golden-yellow form, sinking in up to his sides as those bulges press and rub teasingly against him. You smile soothingly at him, bringing his head to yours for a gentle kiss on the maw, your tail hanging loosly behind his neck as you push him into it.
He gasp and moans softly, faint and suprised, as your thick coils lay along his back, grinding him into your whining and digesting prey, causing his length to slide out of his male slit, blushing more brightly and encouraging him to snuggle in more closely to hide it from view.
The poison-type snake does not seem to be angry or scared though, and actually noses at you affectionatly, looking up with that adorably shy face, so new to being evolved and important.
"We are going to have a nice time getting to know one another, once we have some private time, my handsome and new personal shiny." you speak soothingly and seductively, letting your natural and noble charm work wonders on this other male, feeling him go limp with relaxation, probably used to a life of hard work, but having been cleaned up and given an easy life he seems grateful for.
