A welcome party for new students was held at an izakaya. The female seniors, who don't like the boys who are always paying attention to the cute freshman, Rei, target Rei and play pranks on her. They harass her by forcing her to touch the dicks of naked boys, and as a punishment, they make her expose her breasts in the izakaya! The welcome party escalates out of control, and she is taken out in a car and everyone participates in raw insertion! The female seniors join in the bullying with grins on their faces, and Rei is repeatedly made to cum inside them...
