[Enokido] The New Me (COMIC Anthurium 2024-05) [Coffedrug]

A trembling confession from her kouhai catches Yoshikawa-senpai off guard, but Ryouko's real secret is the arrangement she already has with a senpai whose requests keep escalating—first an alleyway quickie on the walk to school, then letting strangers ogle her bare ass while every crude word about her body makes her clench tighter. Each new demand coaxes out a bolder version of herself, one who rides him so eagerly he can barely hold on, and who moans that he's found her weak spot as he slams into her until they lose all track of time. By the time she's coaxing him to finally cum, 'taking responsibility' has taken on a whole new meaning.
