A Cute And Innocent Student Comes To My House, A Single Teacher Living In A Scruffy One-Room Apartment, Asking Me To Help Her Study! What's More, As A Thank You, She Gives Me The Room...

A very serious and cute student came to my house wearing knee-high socks to ask for help with her studies! It's not a good idea to do it at home, but I had no choice but to teach her. As a thank you, she cleaned my room and did my laundry...but she flashed her panties! What's more, she was wearing a thong! Even though she's serious, her butt is completely visible in the thong! I couldn't help getting an erection...and the student noticed and got excited? I couldn't resist touching her butt and enjoying it, so I inserted myself! I even came inside her!
