The schoolgirl Shiina Sora (MIAE-006) won't let you shoot, leaving you hanging.

That cute schoolgirl in my class is actually a slut who loves to have sex! She even forces me not to ejaculate until she climaxes and is satisfied. If I ejaculate too quickly, she will mock me, saying, "Your penis is so weak, how come you can't hold back?" But because I held back so many times, the pleasure of my final big ejaculation was many times greater!
