Wine, a beautiful woman (even if Sam knew she was really his best friend Colby) and being in possession of George's hormone filled body meant that Sam couldn't resist the the charms of his mother's body. After eating the two made out on the lounge before Colby persuaded Sam to move to his parents bedroom, where she did a striptease revealing lingerie that Sam had never imagined his mother possessed.
Sam was soon naked himself and eager to make love to Colby who was reclining on his parents bed ogling him as he undressed. "Come here big boy" Colby said in a sexy tone.
However Sam froze just as he was about to get onto the bed himself when he heard the garage door opening.
"Holy shit! Someones home!"
"I thought you said your parents were away for the weekend"
"They are supposed to be. Mom's at Timmy's sports carnival and Dad's away with his work"
"Then who is that has just arrived?"
'I don't know" you were starting to panic. "Quick we need to change back! Where are the socks?"
"In your room. Where you changed into George" Your mother's body said. As you both quickly picked up the clothes you had just discarded on the floor.
Naked and carrying George's clothes. You raced down the hall to your own room. You didn't want to explain to your parents about the magic socks. You needed to change back into your own body before you were caught. Colby was right behind you, wearing only your mother's lingerie and carrying the blue dress and and heels she had worn to dinner.
You made it to your room just in time, getting out of sight just as the door to the garage opened. To your relief you noticed the magic sock were on your bed.
However Colby was not so lucky. She was still in the hallway when she was spotted.
