Lisanna, Natsu takes her mouth!

"...okay, let's go with Lisanna then, I already had some fun with Lucy," Erza said after a moment.

"...um, okay, that's fair," Lisanna replied, blushing heavily as Lucy pouted slightly, but did not protest.

"So, you want her pussy or mouth?" Natsu asked as Lisanna proceeded to get on all fours and wait for penetration.

"...I think I'll take her pussy, actually," Erza grinned, getting behind Lisanna and getting on her knees, lining up the fake cock.

"Fine by me," Natsu agreed easily, dropping to his own knees, his erection dangling right in front of Lisanna's face. She only hesitated a moment before wrapping her lips around it, before moaning as Erza pressed into her folds from behind.

"Unh, oh, wow, this feels... Unique..." Erza panted as she bottomed out in Lisanna's folds.

Natsu grinned as he rested a head on Lisanna's head while she sucked. "I can't say I fully relate. I've had a cock all my life, so I'm a little more used to those sensations," he told Erza. "...though to be fair, I've only recently started using it in earnest."

"What, you don't masturbate?" Erza teased as she began to pump her hips in and out of Lisanna, who sucked harder in response.

"...rarely had the time to bother with it," he admitted, pumping his own hips, closing his eyes to take a moment to truly savor the suction on his masculinity. "It felt okay, but not nearly as good as actual sex, so only when I really felt... pent up. Though with how often Lucy ended up naked, I did have some... material to work with..."

Lucy giggled as she continued to watch, playing with her own breasts as she did. Before long, Erza tensed up and moaned, gripping Lisanna's ass as she felt the artificial nerves of the strap on give her an orgasm. Of course, this did not stop her from continuing to thrust into Lisanna until she let out a loud moan of her own around Natsu's cock, just in time to taste his seed spurting into her mouth.

Natsu slumped slightly, panting a bit as Lisanna gulped down his seed. Erza and and Natsu pulled back from Lisanna, panting, and then grinning at one another, both of them wordlessly scheming what to do next.
