[723NNG-004] A cute girl who loves licking is the fourth installment in the school series that followed classes. Ts time it's Serina-chan, number 037, who transferred from a regular school. She's a model student type with a good head, usually showing a miscevous smile, but she's a sensitive and submissive girl who blushes when talking about naughty tngs. As a teacher, my most important goal is to improve by exploring naughty tngs. Recently, Serina-chan has been enjoying giving blowjobs! With deepthroat blowjobs, creampies, and licking, now is the time to enroll in ts school!!
