Hannah
How is she this fast...?!
Even in her demonic state, with all this power of hers, Coconut was somehow still faster than her. "You little brat...!" Hannah whined against the bed, trying to turn her head back so she can actually see what was happening! It didn't actually help her furious blush, unfortunately.
The little one was faster, and just strong enough that her attempts to wriggle out, free her hair, all of that were done with some genuine difficulty. She squealed, her hips jerking forward, and that was all the distraction Coconut needed to force herself into her new big sister's struggling body.
"Nnn...!"
A shudder went through her, arresting all of Hannah's resistance for precious moments.
