[Bonnou no Tamatebako (Nuchitsu Nanako)] Story About A Prison Guard Senpai Getting Fucked Sloppy By Her Huge Kouhai

A strict oni prison guard senpai with plush big breasts and an incredibly sensitive body finds her composure completely dismantled by her massive, imposing kouhai. Her junior's relentless fingering and teasing clit stimulation leave her drooling and twitching, her stern authority dissolving into sloppy, overwrought pleasure. X-ray views of deep internal flooding and repeated creampies tease a total reversal of power as the flustered senpai is claimed again and again until she can't hold anything back.
