Chapter 6 Part 3

Their 'battle' was officially on, with Issei playing with Grayfia's sensitive mammaries and Grayfia in turn sucking on Issei's dick. A groan immediately fell from Issei's lips as the surprisingly enthusiastic devil put every iota of experience she had into the task at hand. Grayfia was a master cocksucker, if a bit rusty. Before Sirzechs had been disheartened and turned off by the fact that nothing he could do would arouse her, the Satan had been happiest when his dutiful maid had knelt down on her knees and sucked his cock after a long day of work.

Grayfia had used it as a bit of positive reinforcement to get her King back on task given just how much he had to do as Lucifer and as a result, she'd gotten exceptionally good at giving blowjobs. Now she was putting all of that skill into blowing Issei and the young man was definitely feeling it judging by the way his cock throbbing and pulsated in her mouth. When he let out a curse and pulled her head back so he could push his length even deeper, right down her throat, Grayfia let it happen and if she could have smiled, she would have.

While his molestation of her tits was arousing in a way Sirzechs had never managed in their long marriage, Grayfia could practically taste victory at this point, her confidence rising as she brought Issei closer and closer to his impending release, now with her throat on top of her lips and tongue. If the young man had thought her skilled before, now he was barely even managing to grope her tits, simply gripping them instead for support as he leaned over her, pistoning in and out of her face hole.

If Grayfia could have smirked around the massive pulsating girth, she would have. The silver haired devil wasn't even gagging, well-versed in suppressing the reflex to do so by now. Even now as he turned the blowjob into a throat fuck, she was in control. And after a moment longer, with her tongue lashing against the underside of his shaft and her throat clenching down along his length, Issei let out a holler and began to cum.

At first, Grayfia remained smug as she began to easily swallow down his load. Making a mess was the antithesis of what she stood for as a Maid and as such, she'd gotten used to swallowing down Sirzechs' loads. Issei shouldn't have been any different on that front, or so she assumed. Grayfia forgot to take into account the large size of his cock as well as his heavy nut sack, which for a brief time rested on her forehead.

Her throat continued to convulse as she swallowed, but Grayfia's smugness slowly evaporated to be replaced by wide eyed shock as she began to realize just how voluminous Issei's cum shot really was. It just kept coming and she couldn't keep drinking down his seed forever. Eventually, his release overwhelmed her ability to swallow and Grayfia began to choke and gag on the copious amount of white hot cum trying to make its way down her throat.

Issei's seed sprayed out of her nose and the corners of her mouth and Grayfia's eyes began to flutter shut from a lack of air. She never did fall completely unconscious, but by the time the young man was done cumming in her nice tight throat, Grayfia was more than a little out of it, her face covered in a white glaze and her vision swimming. Issei pulled out of her mouth and smacked his still hard cock down against the mess he'd made of her face with a chuckle, making a meaty wet slap of a sound when he did so.

"I wasn't expecting that, but I guess I should have. Still, you might regret taking all of my seed in your gullet. I've been told it doubles as an aphrodisiac, though that just might be the love my beautiful women have for me rather than any sort of science."

Grayfia blinked rapidly, whipping her head back and forth to keep the cum from getting in her eyes as Issei crawled over her to place himself between her spread legs. The disheveled maid glared balefully at the young man, but given her current sticky situation (in more ways than one!) Issei didn't really take the glare very seriously, responding to her glare with a cheeky grin as he grabbed her lower legs and began to slowly slide his hands up under the hem of her skirt.

Her legs were covered by long black stockings that went all the way up to her thighs, but once he was past that, Issei found creamy, bare skin, followed by a pair of panties. Running his fingers over her covered mound, the young man was a bit surprised to find that while clearly flustered and flushed with some arousal, Grayfia was barely wet and nowhere near as far along as any of his other honies had been by this point.

"Well, well. You are a tough nut to crack, aren't you? I suppose I shouldn't be surprised, graduating from girls my own age to someone with centuries of life experience. But I'm willing to bet you aren't immune to my affections. In fact, I already have, haven't I?"

Chuckling at his own joke, Issei ignored the way Grayfia redoubled her glare even as he reached back down and pulled up the hem of her skirt, sliding it all the way up her body to reveal her long beautiful legs, covered in black, as well as the panties currently standing between him and the gateway that would lead him to the ultimate prize, her total and utter obedience and devotion.

Issei's eyebrows lifted up as he took note of the fact that her panties were side tied rather than pull on. Grinning impishly at this find, the young man reached out and took hold of one end of the bow resting on Grayfia's hip.

"Well, well. Someone's made it quite easy for me to gain access. This is going to be fun."

Grayfia grimaced and turned her head away even as Issei pulled on the string, unraveling the bow and sliding the silver haired woman's panties right off her body to reveal the waiting pussy lips underneath. As soon as he'd dropped her undergarments off to the side of the bed, Issei's fingers were back and exploring her pussy. The young man licked his lips and grinned as he found her to be wetter inside than outside. She was still getting there, but it was clear to Issei that his efforts were working.

Pulling his fingers free of Grayfia's cunt, Issei brought his cock to bear on the small hole instead, nudging his girthy tip up against her pussy lips and pausing briefly to look her in the eye.

"Ready for round two Grayfia?"

Despite the cum still drying all across her face, the silver haired devil had managed to gain some measure of her calm, cool, and collected attitude back. As such, even with him threatening to penetrate her right there, Grayfia stared at him with an emotionless gaze, the corners of her mouth turning up ever so slightly as she condescended to him.

"Are you, Issei? How many more times can you go without losing this contest of stamina I wonder. Better make this next release count, hm?"

Issei's eyes widened slightly at the challenging tone of her words. His nostrils flared and his tongue snaked out once again to run across his lips. Then, his face split into a massive grin.

"Oh, I'm going to enjoy this so very much."

And then he was inside of her and it became nearly impossible for Grayfia to keep her composure. She tossed her head back, breaking eye contact with Issei as he filled her passage with inch after inch of his massive member. He hit the spot Sirzechs could normally reach with his own cock and then he kept going beyond that, his thick girth striking places within her that had never been touched before, all the way up to the entrance of her cervix before he finally drew back.

Grayfia bit down on her lip hard enough to draw blood in an effort to keep the noises threatening to escape from her throat inside of her mouth. She mostly succeeded too, even as Issei began to saw in and out of her cunt with his huge schlong in a way that quickly had her growing far wetter than his previous actions. Then, to her horror, Issei inadvertently found out her greatest secret.

He went back to her tits, more than likely to overwhelm her with pleasure. His hands squeezed around the base of both of her massive mammaries as he leaned in to once again suckle at one of her nipples, only for a squirt of breast milk to lance out and strike him in the face. The scene froze, even Ddraig who had been enjoying the show all of this time tensing up, her fingers inside of her cunt stopping their back and forth motion.

Grayfia could only stare in abject horror up at the ceiling as Issei discovered something that almost nobody ever had in her incredibly long life. In turn, the young man reared back for a second in confusion before reaching out and squeezing closer to the top of one of her breasts, watching in no small amount of wonder as she kept on lactating.

"… The hell? Are you pregnant?!"

For a brief moment the silver haired maid wondered if she should lie and say yes. Would Issei let her go, would he stop all of this, if she claimed that she had a baby growing in her womb that would never be his? But before she could make a decision one way or the other, Ddraig spoke up, ruining any chance of trying to lie.

"She isn't Master. I would smell it if she was. She's definitely aroused and I think she's lactating because of it!"

Grayfia flushed in humiliation and embarrassment as Issei continued to squeeze her full, milk-laden breasts experimentally.

"I didn't even know that was possible…"

"Neither did I, but it's amazing! Look at the cow go, all that delicious milk! Don't let it go to waste now Master!"

Grayfia shot an angry glare at the crowing dragon girl. Ddraig was far too happy about this for the silver haired woman's tastes and that suggestion… a gasp left Grayfia's mouth as Issei followed Ddraig's order and leaned in to begin suckling from one of her teats. A moan followed shortly after that she just couldn't stop as he started thrusting in and out of her again.

The disheveled half-undressed maid threw her head back in forth, trying to reject what was happening but somewhat unable to with the double sensation of Issei's cock and mouth inside of her and on her tit respectively. Grayfia knew that if she didn't do something soon, she very well might cum around Issei's dick and after that she really wasn't sure what would happen to her next.

There was only one response Grayfia could see here. She HAD to make Issei cum first, even if he came inside, even if he filled her womb with that copious cum shot of his. Grayfia was sure that if she could just coax a second orgasm from the young man, he would undoubtedly deflate at least for a little while and that would make her the winner of their little bet. He would have to release her then. It was her only hope.

Until this point, Grayfia had just let the young man slide in and out of her to his heart's content. Now, having decided to take a more active role in bringing about his climax, Grayfia began to hump up into his thrusts. At the same time, the centuries old devil used the perfect control she had over her own body in a way that she'd never done before now. She began to squeeze down on Issei's shaft with her pussy muscles in a very purposeful manner, milking his dick in the same way his lips were milking her breasts.

Back and forth along her inner walls, Grayfia tightened up her individual muscles as Issei thrust into her and then did the same as he pulled out. Every single inch of her was tight when it needed to be, her inner walls clenching down and grabbing at Issei's member again and again in just the right ways. The young moan groaned against her nipples even as Grayfia tried to contain her own panting and the silver haired maid took that as a sign of impending victory. She just had to do a bit more; she just had to send him over the edge.

Unfortunately, bound to the bed as she was, there wasn't much she could do. Until she realized something critical. All this time, she'd been avoiding straining on her bindings too much for fear of hurting herself further on the light-infused rope. But the constant discomfort had long since faded into the background by this point, drowned out by a growing arousal and the pleasure of Issei's dick that she was desperately trying to resist.
