Holiday shoppers looking to drop some green on Amazon.com could be in for a blue Christmas.

The world’s largest online retailer is under fire because its “Toys & Games” section is stocking a sackload of sexually explicit merchandise, such as the X-rated game “Oral Sex.”

Others include a “Sex Card Game,” featuring cards that “explicitly illustrate either a foreplay activity or a sexual position,” and “Sex Dominos,” for “livening up your lustful evenings.”
