Issei fucks Rias in the Reverse Cowgirl!

"So then, Master, how about I return the favor and give you a blowjob?" Rias asked him hopefully. He considered it for a moment, before he shook his head.

"No, I think we should give Akeno a show, given she wants one, and we don't know when Kiba and Koneko will be back. We should be considerate and end things after the next sexual act so they don't have a high chance of walking in on something awkward," he replied, gesturing for her to stand.

She obliged, standing and letting him take her seat, where he let his manhood, fully erect, stand up. "Oh, you want me to ride you then?" Rias asked.

"Reverse Cowgirl, to be exact," he grinned, to which Akeno brightened, eager to see Rias make love to Issei in such a lewd manner.

"Oh, yes Master..." Rias giggled, turning around and backing herself up to Issei, before sitting down, making sure her legs were parted enough to allow for his penis to go between them. She reached down and gently grasped it, guiding it up into her folds. Once his tip was right at her nether lips, she lowered herself fully onto him.

"Ah..." he panted as he felt his shaft enveloped in the slick, velvety flesh of her entrance. She settled in place, before she started to move her hips.

She moaned and laid her head back on his shoulder. She then giggled as he placed his hands on her hips as she ground them on his. "Master, where do you think you're putting your hands?" she asked him in mock severity.

He went red, and instead of logically realizing she was not actually mad, due to being his genie, he had the knee jerk reaction of removing his hands from her hips. "Sorry, thought I could touch you..." he stammered.

"Wouldn't you rather grope my boobs?" she then dropped the other shoe.

"...I should have seen that coming," Issei remarked with a grin as he reached up, cupping her breasts from behind.

"Mmm, yeah, that's more like it," she crooned. Her pussy tightened around his cock.

"Heh, this of definitely good masturbation material for later..." Akeno shifted slightly, still fondling her own tits. Rias grinned, wriggling a bit more, flaunting herself being fucked for Akemi's viewing pleasure.

Issei bucked his hips up into Rias repeatedly, moaning and kissing her neck. "Oh, oh yeah..." he grunted.

Rias twisted her hips on his cock, and bit her lip. For several minutes, they kept this up, until Issei felt his cock begin throbbing. "Master, I'm close..." she panted.

"Me too!" he gasped out, before his seed shot up into her, and she tensed up as she felt herself cum again.

"Unh!!! Yes!!!" Rias cried out, feeling her insides spasm as his semen splashed into her core. After a moment, they relaxed, catching their breaths. "Mmm..." she panted. "That was so good, Master..." she crooned. She slowly got up.

"No kidding," he nodded as she turned, and leaned down, kissing him passionately.
