Show in Prudential Center where Demi Lovato & Kehlani Tsunami have performed was everything but prude. During their performance they simulated lesbian sex, as Kehlani was laying on the bed set on stage, Demi straddled and started rubbing her vagina on her. Kehlani returned the favor by rubbing Demi’s legs at which point singer got really horny an almost put her wet pussy on other performers face, but remembered they are on concert, and left that part for later.
