Intro. Your wife and her best friend invited you to a party. Your wife is the brunette and her friend is the blonde. While at the party, they stuck close to you, enjoying the music and drinks and having some fun, but then they went off for 5 minutes and returned, when they got back, they were clearly horny, and your wife says they got some ecstasy and took it. They're high on horny drugs and they both want you, so you take them home

After party fun
