Reverse Cowgirl!

"Well... considering how you like to watch others have their fun... how about flipping that script?" Issei suggested with a grin, and Akeno blinked.

"Oh? What do you mean, Master?" she asked, the amethyst in the collar gleaming as she spoke.

Issei replied by sitting on the side of the bed, and patting his lap as his erection stood at the ready. "Have a seat, back to me," he instructed her.

Realizing what he was getting at, that he wanted her body on full display for Rias and Asia while he fucked her, Akeno flushed, but not so much in embarrassment, but in excited anticipation. "Oh, that sounds like a great idea~!" she cooed, sauntering on over, before turning, and pausing for a moment to let him take in the view of her ass, before backing herself up to straddle his lap.

Gripping his own manhood in his right hand, he held it in place, ensuring she had no issues with impaling herself on it. Her breath hitched as his member parted her folds, taking him into her. "Unh... wow, this feels amazing..." she crooned as he cupped her boobs, and started kissing her neck.

Naturally, Rias and Asia were watching with rapt attention, Rias starting to tease Asia's body with her fingertips. "Hot to watch, isn't it?" she purred into Asia's ear, before giving it a little nibble.

"Unh... yes, it is..." Asia panted, squirming against Rias. "Suddenly, waiting my turn seems so much easier..." she admitted, making Rias giggle as Issei and Akeno started to grind their bodies against each other.

"Yes, seeing Master enjoy himself, and the pleasure our harem sister is receiving at his hands really helps set the mood, and build up the anticipation, doesn't it?" she teased Asia, who nodded.

"Mmmnh... wow, they're really enjoying the show, aren't they, Master?" Akeno crooned, relishing every sensation, Issei's strong chest against her back, his lips to her neck, his fingers and magically warded claws beginning to pinch and lightly tweak her nipples, and his manhood in her folds. She bucked her hips against him, crooning at the feel.

"As they should," Issei grunted, before almost reluctantly taking his left hand from her breast. She almost protested, before realizing what he was doing: the hand was going down her torso, right down to her pussy. She yelped and whimpered in delight as the claw tip began to stimulate her clitoris.

"Unh, oh, fuck yeah!" she gasped as her motions started to become almost frenzied, shamelessly writhing her body for Rias and Asia to see. She was already extremely happy she made the decision to join Issei's harem. He had definitely learned how to pleasure a woman quite well during his time with owning Rias. "You're going to make me cum already~!" she whimpered as her cunt clamped down on his shaft.

"Good timing, I'm about to pop off myself!" he grunted, giving his hips a final buck, burying his member fully into her entrance, before he released his load right up into her core. She let out a cry of rapture, her eyes just about rolling up to the top of her skull as she spasmed in ecstasy.

"Oh... oh wow..." she wheezed, relaxing against him. She then blinked as his draconic hand moved back up, and cupped her chin, gently, but firmly. Her face was turned towards his, and he lowered his mouth to meet hers. Without hesitation, she puckered her lips, and moaned in bliss as he kissed her.
