Rias' POV
"I've told you, that's not going to happen." I glared at my Sister-In-Law.
"I don't believe you quite have a choice in the matter Rias." Grayfia responded.
"No I do." I smiled "I'm done being pushed around, my eyes have opened, I'm my own woman."
"I know what you've been doing." Grayfia said "The Personality change, The noticeable growth of your chest, the sudden rise in the number of your Evil Pieces…I hope you have not broken-."
"It's in tact." I glared out the corner of my eye "But Riser will never get it, not without a fight at least."
My Sister-In-Law Grayfia has come to ensure I'm still fit for that arranged marriage to Riser Phoenix. I've told them the man disgusts me, even more so now that the deeper more freeing parts of my personality have bubbled to the surface.
"You mentioned…you know about what I am now?" I asked.
"Yes, all the puzzle pieces fit. You're not very subtle about it, you're playing a dangerous game" She said.
"Relax I turned two guys into a girls and gave one ugly duckling a makeover, if anything I helped.
"You're Succubus." Grayfia scolded "A danger."
"Good…" I licked my lips.
I suddenly slammed her into the wall "Then you'll understand that I'm just dying to feed off you right now."
I forced magic into her body to stop her movements.
"You're magic…countered me?" she gasped "You've gotten stronger than I thought."
"Hmm." I smirked "You shouldn't have underestimated me….big sis."
I reached up and aggressively grappled one of her breasts "You're hiding your sexy body, is it because you want to keep it just for my dear brother? Show me, we're family after all."
I ripped that ugly maid outfit she wore open, causing her breasts to spring free.
"Now listen you best play along." I smirked "You know now that I have all this magic at my fingertips I can mold people into whatever I want, male, female, bigger or smaller…for example, suppose I was just dying to see how cute my nephew would look as my sexy little niece."
"You wouldn't." she glared.
"You've seen the new me, I would." I smirked "I feel so alive now, so bold, and so sexy. The old cute, nice Rias is long gone…the new me won't hesitate to crush people who try and stop me. Here's the deal, I'll leave your sweet little boy alone, but in exchange you're going to pleasure me right here and now…oh and when you get back, you're going to start recommending that Riser not try to marry me, you're not going to say I'm used goods or anything like that…but think of something. Besides…"
I licked her cheek "There's no way that wannabe Sultan could handle a woman like me. I'm no one's pet, I'm the dominant, I'll crush them under my jet black heels."
"You have to know I'm not backing down." I licked my lips and I rubbed her thighs "So, what's it gonna be, will you fall on the sword for your son…or let me make him a real man?"
"What…happened to you." Grayfia sighed.
"The old Rias is gone, this is the true me…the me that was too subdued to come out, but now that I'm awake…I'm not turning back, it's much more fun to be a sexy succubus than a little celibate. I'm a demon after all, I should do sinful things yes?"
"You…you've changed." She sighed.
"So what will it be?" I asked.
She turned her face away "Just…take me and get it over with."
"How sweet." I said kissing her neck.
I slowly pushed her to her knees "Let's start with a blowjob okay."
Grayfia brushed her hair back before she moved forward and started licking my cock. Once she opened her mouth to accept me I let out a moan.
"You're good at this." I said teasing my breasts "You must have lots of experience with this, I bet you're a great wife."
I glared at me as she kept sucking, she didn't really care for this, but to protect her family she was willing to give herself to me. I watched as she bobbed her head and her heavy breasts wobbled in unison.
"It's funny I knew I wanted a body like you when I was getting older, but I've already outclassed you big time." I said bouncing my large bust.
"BLURG!" Grayfia moaned as she sucked on me more and more.
She was moving her head at a rapid pace, I had never received a blow with this much force behind it, she was good! I felt my balls keep slapping against her chin and I knew at the rate she was going I was gonna cum before I knew it.
"Oh yes…oh that's it…just a little more." I said putting my hands on her head.
"GRUK!" she sucked more and more until my testicles tingled and I couldn't hold it.
"OHHHHH!" I screamed as I filled her mouth with cum.
Surprisingly Grayfia was good enough to swallow every drop, she may have been against this at first but here she was slurping it down.
"That was sexy." I licked my lips "Let's get to the really fun part though."
I pulled out my dick and laid on my back "Well, hop on."
Grayfia begrudgingly took her dress all the way off and straddled my waist, I reach back to grab her ass as I slid my cock into her.
"Hmmm." I moaned "That's perfect."
"Ha!" Grayfia gasped as she started rolling her hips.
Her pussy was surprisingly loose, I mean she has had a child. I bucked my hips to match her movements, my tits jiggled and rolled around from the force and I loved it. Grayfia was rocking her body well, her own chest flopping about and her ass crashing down onto my thighs.
"Bounce more." I commanded "I wanna see those tits shake."
"OUF!" Grayfia groaned moving faster and faster.
"See, sex with me is wonderful." I smiled "And soon you're going to climax, and I feed on your energy."
"You…just…get it over with." She begged.
"Oh no, I'm going to savor this one." I smirked.
I grunted and started forcing my cock deeper into my sister, hold back all she wanted she couldn't stifle her moans.
"I can see the look on your face." I smiled "just admit you like this, me, the beautiful young succubus, pounding you, the mature sexy devil."
"HMMM!" she bit her lip "Shut…your mouth."
"How rude, I might have to stop if you say that." I smirked "I'm in charge here, got it!"
I gave her a powerful thrust, causing her she moan loudly.
"See, you like it."
"Just…finish already." She begged "I can't take this!"
"That's what I want to hear." I smirked "Now, cum with me."
I thrusted into Grayfia as she bounced on my rod, my insides were turning as she bucked and began to lose control.
"Ha…ha…HAAAAA!" she moaned as she climaxed.
"YESSSS!" I screamed absorbing her energy and filling her with my spunk.
I snickered as I laid back and Grayfia got off me.
"I must return home." She said picking up her clothes.
"Don't forget our deal." I smiled as she left.
Even if Riser still pushes for this annoying wedding, I'll find a way out of it…he's peerage is all girls correct…oh this could get fun.
