Velvet Merlin

A girl jerks you off while you wear a blanket as a wizard robe. She must use both hands as if grasping a hilt of a sword, pulling it from the stone. As you ejaculate, she points your dick at your own chin, giving you a drippy white beard.

I went to kiss my kids good night and forgot my wife gave me a Velvet Merlin.

Merlissa

The hottest, sweetest gal you'll ever meet. As sweet as her 'honey bee' namesake, Melissa, except with an extra 'r' for raunchy. Once you meet a Merlissa, she will sweep you off your feet like a whirlwind, leaving every other girl you met in a wake of destruction, and you wondering why you ever wasted any time with any of the others of the past.

'Have you ever heard of a girl called Merlissa?'

'Have I HEARD of her?? Bro she's a total unicorn'
