He rests his back against your chest, legs spread as you help him finger himself and guide his other hand toying with a nipple by the wrist. Your stardust pants out hot breaths, having gotten over his initial lip biting once you noticed and carefully redirected him into freely letting them out. Moans, whimpers, and more all fall from his drooling mouth as you play with him, now.
Mouthing the shell of his ear, you gently tease it between your teeth and suck. You relish in the sound that startles out of him and keep at it for several moments longer as he squirms happily and gasps, pulling away after pressing a soothing kiss (or three) there. Dolls normally aren't supposed to move on their own but your stardust has special privileges! You can't help but forgive his little character breaks on top of finding them endearing, especially when he's so willing to share his body with you…
"Looo-p," he slurs out, no doubt feeling his next orgasm approaching. Obliging and quickening the pace of your joined hands inside of him, you move more insistently into a certain spot that makes him mewl; it's being built up inside of you, too, this entire time you've been leeching off his senses. You suck on and nibble at his neck and shoulders to add onto the collection of bruises you've left already, causing him to cum for the third time.
