Yuko Matsui is a sex-loving married woman who was looking forward to the "instant sex" shoot. In response to her preference for rough sex, the whole film is hardcore sex! When she is masturbating, a huge cock is suddenly inserted and she climaxes with the pleasure of a real cock that she could not experience with a vibrator! Without a break, a second and third cock are inserted and she screams loudly while squirting! Three cocks attack her at the same time in a 4P gangbang, raping her upper and lower mouths and ejaculating into her mouth continuously! After being covered in a total of six loads of semen, she screams so much that she can't even make a sound at the end!
