Satoru rumbles approvingly in reply, wiggling a third finger inside and giving her slow thrusts with a little twist of her hand to make sure her knuckles bump against Suguru's opening each time. She keeps her fingers deep, thrusting them against Suguru's inner walls with thrumming little vibrations of her hand. If Suguru likes the fullness, she can do that, making sure to keep her full while making sure there's enough stimulation to keep it interesting, and making sure that the heel of her hand bumps against Suguru's clit with each of those thrusts, letting her grind each time Satoru's fingers are buried deep.

"Good?" Satoru asks, warm and playful, nipping at Suguru's jaw with happy affection while she fucks her.
