The women, both 22, pleaded guilty to knocking out a 27-year old man with a date rape drug, tying him up, stripping him and abusing him on the sofa in his apartment in July 2010.
The court found the women guilty of sexual assault, false imprisonment, causing bodily harm, and breach of narcotics laws. Each were handed 14-month suspended sentences with a three year probation period.
As part of their vendetta, the women stuck pink feathers to their former partner's genitalia, glued his testicles to his thigh, painted his penis with pink nail polish, sprayed him with fake tan, dressed him in a bra and mini-skirt, and applied make-up to his face.
“Hey boys, watch out: this is what happens if you don’t keep your dick under control,” read a message written on his chest with waterproof marker, according to TeleZüri television station.
The young women then took pictures of their handiwork and left one at the scene, having printed it out on a photo printer they brought with them.
They left their captive tied up in his apartment, where he was later freed by a flatmate.
Afterwards, they threatened the cheating boyfriend on Facebook, and told him they would publish the photographs if he sought revenge for the attack.
The women hatched the plan after learning of the victim's infidelities. The 27-year old was involved with one of the women but cheated on her with other women. His fatal error, according to NZZ newspaper, was when he made a pass at the second woman, his girlfriend’s best friend.
Feigning a mutual romantic interest, the friend drugged the love cheat in his home before contacting her accomplice.
NZZ newspaper reported that the accused “presented themselves to the court as nice, preppy young women, both dressed in striped blouses, with long hair - one blonde in a skirt, the other black-haired in jeans - both with guilty and remorseful faces.”
During his verdict, the president of the court spoke of the women’s extensive guilt. He condemned the use of a date rape drug as being far from harmless and said that their level of aggression was alarming.
