Madagascar Suprise
You're fukin a girl from behind, and just as you pull out, your friend slides in like he was there the whole time. Then you step out and yell her name, and she loses her mind because she thinks she was fukin by two different guys at the same time.
She: 'I felt two different guys!' Me: 'That's because two different guys were fukin you.'
Girl: 'You were the best part of this!' Me: 'Yeah, till my buddy came in and made it a party.'
She: 'I thought you were a legend!' Me: 'I am. But my buddy's a legend too, and he just took over.'
