I took my student Erina, who is petite and fluffy and has a lovely smile, on a hot spring trip. She is excited about the big cock, but she is happy to say, "It's a tight fit," and opens her small mouth wide and stuffs her cheeks while sobbing. Even if she says "I can't stand it! I'm going to go!" She said, "I like being strangled," and when Erina showed her true nature, she smeared her face with semen and said, "I'm a prisoner of this cock."
