I got tired of my extremely sis-con sister being all over me. No matter how much she's a woman, I honestly don't feel any special emotions towards her as my sister. So I mustered up the courage to firmly reject her, but then my sister flew into a rage and restrained me while I was sleeping so that I couldn't move. Confused, she gave me a wicked smile and said, 'I'll make you cum until you like your big sister,' and I kept getting made to cum, now I'm completely exhausted... My sister is unexpectedly perverted and keeps hitting my pleasure points hard...
