She wanted to go to a party, but her boyfriend doesn't like parties... he's always tired. Since she already knew he wouldn't want to go, she prepared a shrinking potion for him, so he couldn't deny it. Since his size would be insignificant! So she did. He took the potion, she took it to the party, inside her panties. At the party, she made out with other guys in front of him, and he couldn't do anything because he became tiny... On the way home, she had fun with him!
