Have Diana ride her!

"You know what? How about taking it for a ride?" Zatanna asked, turning slightly so she could lay back on the couch. "I feel like relaxing, and letting you do all the work here..."

"Okay, Mistress!" Diana chirped, and stood, before mounting Zatanna, slightly awkwardly as the back of the couch got in the way of one of her legs, but with a bit of wiggling about, she got a decent position, and lowered her pussy down on Zatanna's temporary futahood.

Zatanna crooned as Diana's folds parted to allow her in. "Oh wow, that feels pretty unique," she noted as Diana stabilized herself by resting her hands on Zatanna's breasts.

"Of course... This is your first, and hopefully not last, time with a cock," Diana crooned as she fully lowered herself down on Zatanna. She then began lifting and dropping her hips repeatedly.

"I might just do this more often, assuming Felix allows it," Zatanna noted. She reached up and started to grope Diana's boobs in the same manner as Diana groping hers.

"Mmm, he should," Diana noted as she kept working her hips up and down Zatanna's shaft. "You're a pretty dependable friend with benefits for him..."

"A lot of benefits, as it turns out," Zatanna joked as she bucked her hips up into Diana a little. Diana crooned as she squeezed Zatanna's cock with her pussy.

"What can I say? We Sex Genies can do a lot..." Diana moaned as she frantically moved her hips against Zatanna's.

"That's for sure," Zatanna moaned as she felt something building up. "...hey, do you think I'm about to cum?" she then asked Diana, unfamiliar with the sensations of a male orgasm.

"Based on the throbbing I feel in my cunt, I would say so!" Diana moaned, and Zatanna gasped out as her nut burst, gushing right into Diana's pussy.

"...oh... wow..." Zatanna panted as her futahood was spent for the moment. Diana pulled off, and grinned.

"That was a bit quick, but that was your first time with a dick, so it's to be expected," Diana assured Zatanna.
