In Curious Fruit, an innocent girl observes two physically exaggerated sex fiends tinkering with each other in a public restaurant.  She follows them outside; they capture her and take her to their dungeon full of sex slaves.  They chain her up and dress her in S/M gear.  Soon she is fucked by a wavy-haired guy, whose cock is a blinding-white cylinder, and when he cums things get appropriately intergalactic with an explosion of stars.

In Sacred Girl, the brother of a menstruating girl licks the blood off his sister's thighs.  Later, when she jerks off, she thinks of him.  He does the same, masturbates and thinks of her; plus he's got surveillance cameras all over the mansion to fill in the imaginative gaps.  His girlfriend finds out and gets aroused.  What a relationship!  Later on, brother and sister crave intimacy.  "Big brother," she says, as the two fuck.  Throughout the video, when fingers explore pussies, the sound effects are moist, crunchy, and tactile.
