Yet another task

At midnight the four beings appeared. "Well, looks like you're now the office or school sluts," said one.
"Yeah, whatever!" said Phoebe, "Just give us our final task!"
"Oh, this should be an easy one for sex fiends such as you," said the second, enjoying the evil eye the girls have him in return.
"Your task," said the third, "is you each must seduce and have sex with a virgin boy who has not yet seen eighteen years. You each must seduce your own virgin: no sharing."
"Yes," said the fourth, "but you must first accept his seed into your vagina, then you must accept his seed into your anus, then you must accept his seed into your mouth all within an hour. Oh, and just for your further degredation, you are not allowed to let him wash his genitals or let you or anyone else do it for him until after you accept his seed into your mouth."
"You have 24 hours!" said the first.
"I don't know how," said Prue, "buy you're going to pay for this!" The sisters wheeled and left.
The four beings laughed. "Let's make this a lot harder for them," said the first.
"How about we give them horrendous halitosis and body odor?" said the second.
"Or make them only able to speak in gibberish when trying to seduce their boys," said the third.
"Or we could cast a spell on them that makes them look like hiddeous hags to everyone but themselves," suggested the fourth.
