欲火中烧的秘鲁宝贝看到她的姐夫自慰并要求被性交

Disco night, so you're getting ready to go out with your sexy girlfriend to dance. As you're showering, your sister-in-law sneaks in and sees you naked. She gets horny because of what a nymphomaniac she is, and starts touching and masturbating on your bed. You come out and see her naked and horny. You know what to do, the party starts right in there, so why leave.
