Mai is still a naive girl in a sailor uniform. She's finally gotten used to naughty things recently, and even though she's shy, she invites him by saying, "Teacher... I'm not used to it, so please teach me a lot." She reacts sensitively just by stroking her D-cup breasts, and gets so excited just by sucking her teacher's big dick that she stains her panties. When he inserts her in the cowgirl position, her love juices drip endlessly and her hips move violently. In the end, she can't hold back and cums inside him.
