The Secret of the Close-Knit Brother and Sister: My tomboyish sister has recently started wearing skirts. She does this to secretly have sex with me (her brother) without our parents finding out. Hiding in the blind spot of the sofa, she straddles me, pulls down her panties over her skirt, and inserts her cock. She enjoys the thrill of multiple orgasms with slow, deep thrusts, and then finishes by cunnilingus and internal ejaculation.
