HUNTA-811 — "No, I'll Become Stupid!" My Super Serious Childhood Friend Started Studying Dirty Stuff... Even Though I Knew It Was Wrong, Her Body Started Craving My Dick...

My childhood friend has excellent grades and a lot of pride. She always makes fun of me for failing grades, but in fact she knows absolutely nothing about sex! When I make fun of her, she gets mad and starts studying erotic knowledge from that day on!? Then...my childhood friend, who can't stop being interested, changes so much that even though she knows it's wrong, her body wants my dick and she drools, saying, "No, I'll become stupid!!" I get in the mood and start thrusting, and she screams and cums so much that it can't be undone!
