"I said FASTER Pony" Lisa said whipping him

She seem annoyed then she smiled

"I know something that will make you go faster"

She went into her closet and got a strapon. She put it on and shoved it deep in Billy's ass. She started whipping him put her feet up

Billy moved around the room as his sister slammed it in. She pulled his hair

"Thats it faster...FASTER!!!"

She open the door and Billy walked out of the room

"Love my little Pony" Lisa teased.
