[Maruarai (Arai Kazuki)] First Night? C1BS Festival OMAKE (Bokutachi wa Benkyou ga Dekinai) [Moobortin]

Mafuyu Kirisu greets Nariyuki on their first night together clad in a corset and garter belt, her usual composed teacher persona crumbling into flustered embarrassment when he stammers at the sight of her. Once the shock wears off, she surrenders completely — riding him on top, sweat-slicked and crying out for more as their awkward first time blooms into earnest, passionate lovemaking. A bonus omake caps the night with a waist massage gone hilariously wrong, leaving the pair as adorably flustered as when they began.
