Shampooing 

Engaging in sex while shampooing your partner then Mid-coitus, one person bites the neck of the other, locks their arms and legs down and goes into a deathroll, all while maintaining insertion. Upon completion the man finishes in the womans ear and then proceeds to mushroom slap the woman being sure to leave a print.

I heard Candi and that Tranny Lizzie shampooing last night, and I saw the print to prove it! I'm gonna have nightmares for weeks...
