[Maekawa Hayato] Coaxing Onee-chan (Comic Mugen Tensei 2014-04)

A doting older sister proudly shows off her precious little brother Keita to her university friends, but the drinks go down easy and leave her soaked, stumbling, and stranded after the last train. Carrying his drunk big sister to a hotel bed proves too much temptation—he coaxes himself into her sleeping body and takes her virginity, begging forgiveness even as he pushes through her hymen. Yet when she wakes glistening and furious, the scolding melts into a blushing plea to make love one more time, and the siblings carry their new secret into a shared bath and a promise of a next drink for just the two of them.
