The ninja boys keep geting humiliated by Airi during sex training, so they decide to strike back ! For that, they beg all the other kunoichis in school to let train in sex with them; and being kind-hearted girls - as well as debauched little sluts - they are more than happy to oblige. When the boys will be ready, they will gangbang Airi, and make this delicious - as well as mischevious - slutty kunoichi submit to their cocks !
