Yui Mihama's second exclusive release! Yui, who still has room to grow, begins erotic training to help her grow! She's tied up and made to cum over and over again, her nipples, clit, and insides are stimulated with toys at the same time, and she squirts repeatedly in a threesome with two big dicks. The dicks of the tough actors awaken the innocent vagina of this AV freshman! A girl who hasn't yet realized her potential is finally able to grow a little more in these three worthwhile scenes!
