Zu Besuch bei Familie Geilhaus (1997)

The Geilhaus family is in the market for a new house. Unfortunately for everyone involved, the entire family is perpetually and extremely horny. Any contact with the opposite sex immediately triggers intense sexual activity — “dripping pussies and hard cocks” as one description puts it.
During a house viewing, the real estate agent quickly notices the family’s condition and ends up fucking the future lady of the house right there on the premises. The rest of the family members are equally uncontrollable whenever they encounter someone of the opposite sex, leading to a series of escalating orgies and group encounters both inside and outside the family.
