Hell to the yes!

"Sure, go ahead," he nodded eagerly, and Diana smirked as she began to lather up her own boobs.

"Oh? And just what might this little shower activity be, hmm?" Zatanna asked curiously before Diana handed her the soap. "...I'm guessing we use our breasts to wash his body?"

"You got it!" Diana giggled. Zatanna smirked as she began putting the soap on her own tits. "It's not the most efficient way of cleaning Master, I know, but it certainly is pretty damn fun and sexy!"

"Say less, I'm in," Zatanna grinned, getting her boobs all soapy. "So, how do we get Felix flustered this time?"

"You go high, I go low?" Diana suggested. Zatanna considered, before she nodded.

"Works for me..." she replied, starting with Felix's chest, rubbing her boobs against it. In kind, Diana knelt behind him, focusing of on his thighs.

Felix moaned in pleasure as the two got to work on cleaning up his body with theirs. It was immensely hot. "Heh, do you like this more than when I do it myself?" Diana asked him as she continued to move her soapy tits up his back.

"It has its own charm, but you doing it yourself also has a certain charm to it," he replied as Zatanna got his shoulders.

"Fair enough..." Diana smirked, getting his shoulder blades.

Felix relaxed and simply enjoyed the sensations of them double teaming him. Eventually, they finished up, and Zatanna asked, "So... Who wants to escalate things?"
