esk09-1 Mari-chan, trembling uncontrollably as she tries to hold back

I never even told her to hold back, but Mari-chan, on her own, asks, Am I supposed to endure this? and tries to put up with it.

But she’s clearly nowhere near calm, her body trembling hard, shaking all over in tiny bursts.

She isn’t thrashing around; she’s trying to endure it right there, but sweat is already starting to gather under her arms and around her inner thighs, and she can’t hide it anymore.

It seems like she’s especially sensitive above the ribs, because even the slightest touch makes her break down right away with a flustered laugh.

She’s trying so hard to hold back, but not managing it at all, and that’s what makes her so cute.

Mari-chan trembling as she tries to endure it is the best.
