Summary: After Riser is defeated and the engagement between him and Rias broken, Venelana and Grayfia decide to visit the man that has so captured the interest of their Rias.
Grayfia and Venelana couldn't care less about their respective husbands at the moment, however. Here was the one devil who had managed to help Rias out of her predicament. And he was so unbelievably powerful, handsome, and with the biggest cock either of them had ever seen. Having taken complete leave of their mutual senses, the powerful older women cry out, the two MILFs shaking and shuddering under the combined onslaught of Issei's cock and fingers.
Venelana definitely gets more from his cock than Grayfia gets of his fingers though, and soon enough the flaxen-haired beauty's eyes are fully rolled back in her head, her tongue lolling pointedly out of her mouth. She looks rather silly like that, but then, she had pretty much said it straight up. Issei has turned her into his tight little living onahole, her tits bouncing up and down all over the place as she cums again and again upon his cock.
By the time he finishes inside of her, Venelana is insensate, in a pleasure coma, and likely not going to be coherent any time soon. Which means it's time for Grayfia. The maid whimpers, as Issei moves over behind her kneeling form and digs his hands into her ass cheeks.
"I-I apologize for interfering, m-my Lord. I should, a-ah, never have gotten between, oooh, you and Rias."
Completely unbidden, the apology makes Issei cock his head to the side… and then nod approvingly. His cock slides up and down her slit for a few moments, before he slowly sinks into Grayfia's depths, much slower than he first penetrated Venelana. The powerful maid cries out, whimpering all the same as he stretches her, inch by inch.
Only once he's fully hilted inside of her does Issei stop and reach forward, wrapping his arms around her and grabbing her tits hard.
"I forgive you, Grayfia. Let's be friends from now on!"
Then he starts to fuck her, juxtaposing his sunny attitude and seemingly cheerful words with the most powerful plowing that Grayfia Lucifuge has ever experienced. Tears streaming down her cheeks, tongue sticking straight out of her mouth, eyes crossed, Grayfia squeals and shakes and shudders through orgasm after orgasm.
"Y-Yesh! Let'sh be best frieeeeeendsh!"
Her tongue wagging all over the place slurs her words, but Issei doesn't seem to mind, just grinning and fucking her even harder. She ends up much the same way as Venelana in no time at all, his immense cock size combined with his domineering nature and his incredible power sending her into a state of euphoria from which returning would certainly be a chore and a half.
But that's alright, because Issei has a third woman to fuck. Rias ends up taken on her back, same as her mother. Unlike Venelana however, Issei only puts one hand on her tits. The other hand intertwines with one of Rias', their fingers locking together as he thrusts into the red head again and again. She might be younger, she might not be as strong or quite as voluptuous as Grayfia or Venelana, but Rias has one thing over the older pair of devils that they will never have. She was Issei's first.
As he fucks her hard and fast all the same, Rias moans into Issei's mouth, her legs high in the air, half-wrapped around his waist and half bouncing back and forth over his back. Her pussy walls clench and squeeze down along his cock, and her entire body shudders and quivers its way through orgasm after orgasm as he fucks her senseless.
It wasn't like this, at the start. When Rias initially saved Issei, he wasn't this way. But then, Riser had shown up and it was like night and day. More than that, Issei had unlocked his Sacred Gear, which was far more than even Rias bargained for. Not that she was complaining. Having the Red Dragon Emperor by her side, as her lover, was more than the red head ever could have hoped for. He'd saved her from a fate as Riser's bride, saved her and the female members of her peerage from having to submit to that bastard.
In comparison to that… was giving over her mother and her brother's wife to him really that much to ask? Yes, Rias hadn't just stayed quiet because she didn't know what to say. Venelana and Grayfia might have thought otherwise, but it was true. Issei had been right on the money when he'd asked if they were only there to fulfill Rias' promise of 'all the oppai that Issei could desire' to him.
Her big-dicked, domineering lover wanted to be a harem king. And so, Rias would help him do it… no matter who she had to feed to his overwhelming libido and ever-insatiable lust for more and more women.
With a groan, Issei spends himself a third time inside of Rias, creampieing her just like he did Grayfia and Venelana. Squealing, eyes rolled back in her head, Rias lets herself enter the same state of ahegao as those two older devils at last, knowing that she can trust in Issei to look after them all… even if he probably will end up fucking their insensate bodies some more to calm his ever-raging libido.
