Rias (Pov)
While our Mc was busy in the Underworld Rias had taken her mother's advice and teleported directly into William's bedroom in a see through baby doll. Arriving in William's room I started to look admire everything that was in the room seeing that his room is empty so I'm guessing that his harem members were sleeping in their own rooms tonight.
Glancing at his night stand I could see a picture frame with him and the members of his peerage/harem members in one photo as well as pictures of me and him me by my self as well as Akeno which causes me to smile as I remembered everything he had helped us with since meeting him. While sitting on his bed I begun to get a little nervous and worried at the same time but at that exact moment that's when I saw it a magic circle appeared in the middle of the room.
Back to Mc's Pov:
Stepping out of the magic circle I could see a blushing red head Rias Gremory sitting on my bed William ( well isn't this a surprise what can I help you with this late night visit)? Rias ( I just wanted to say thank you for helping me get out of this arrange marriage and you even treated me like any other regular girl plus you get along with my peerage members. What I'm trying to say is that I know that you already have wives and probably more down the road which I know that am Akeno will be one of them and maybe Koneko when she gets a little older and that you're also with my mother but just maybe there's room for me as well)?
She asked me as she started to undress showing me her naked body and curves without any care in the world. William ( Rias you do know when you become an dragon's mate it's for life right and you'll never be able to leave me). Once Rias had heard what I've said she had ran and jumped into my arms as she started to kiss me which I returned in full as I started to dominate the kiss like I've always do with my other mates.
As our tongues intertwine with one another I begin to make my way down to her perky ass that almost had the same elstasticly as her mother Venelana. Starting to squeeze her ass which causes Rias to moan into my mouth as we continued to make out with one another soon Rias broke the kiss due to the lack of oxygen Rias ( I could get addicted to this no wonder why my mother and the rest of your mates enjoy kissing you all the time) hearing what she had to say only made me chuckle before saying William ( then you're going to get addicted to what I'm going to do next) with that I slipped my hand in between her legs into her panties as I started to rub her clitoris.
Sliding my ring finger into her moist pussy that had gotten a higher moan from her soon I started to kiss and niple on her neck as I continued to finger fuck her pussy as I continued to enter more finger inside of her every second that made her moan even more. William ( why don't you get rid of your lingerie and drop to your knees to get me ready to enter side of you) I told her in a subductive tone in her ear. Listening to my command she had removed her see through to revealing her perky pink nipples.
Once she was on her knees her trempling hands had reached out to my waist band and revealed my 13" black cock that had made her gasp in shock Rias's thoughts ( my mother had taken that massive thing inside of her more than once plus the rest of the people he had introduced me to) she thinks to herself while holding onto my cock William ( just don't hold onto it Rias go ahead and give it a lick and put it in your mouth) I told her in the same tone as before. With that she sticks out her tongue and begun to lick the tip of my cock.
Licking the tip of my cock as wrapping it around at the same time as she started to stroke my shaft as she sucked on my head as I placed on of hands on top of her head. Reaching her other hand on my balls as she started to play with them feeling her playing with my balls while having her soft lips sucking on my head I couldn't but help let out a moan of my own. Grabbing the back of her head as I started to feed her my cock which causes her to gag a little.
Which had made her drop hands to her sides giving me a free ride of using her mouth as a fleshlight pushing her head further down my cock as I started to fuck her mouth while hearing her gag with each of my thrust which made her eyes rolled into the back of her head Rias's thoughts ( this feeling of being subdued by him is making me lose my mind is this what my mother is feeling every time she is with him just by servicing him is making me having minor orgasms Akeno I believe that you've met your match). Lost in her own thoughts I had pushed my shaft further down her throat.
Which made her squirt right on the spot as her body started to pulsate due to her release which I've decided to go ahead and cum directly down her throat. That had made her eyes open wide to have my cum down her throat made her have another orgasm once again pulling out my still errected cock that was covered in her saliva William ( now let's get to the main event) with the same subductive tone lifting her up as I started to walk towards my bed with a weaving Rias in my arms as my cum dripping from the corners of her mouth.
Looking at Rias's drenched panties removing them just to see her perfectly waxed pussy that was juicy with her own juices William's thoughts ( well I guess it's time to add another mother and daughter pair to my growing harem and claim another virginity) I said to myself while I lined myself up with her enterece and with one final push I had claimed her as my own which had made her come to as she squirted all over my cock William ( now you belong to me and no other man can have you).
With that I plunged my cock deep inside of her breaking her hyman claiming her Virginity as my own pounding away at her pussy feeling the same feeling as the time with the other girls as my own aura started to mix with Rias growing stronger with one another. Having her a squirting mess as I go in and out of her William's thoughts ( she's just like her mother when feeling pleasure) I've thought to myself while going in and out of her pussy grabbing her by her ankles as I started to go balls deep inside of her pussy hearing our skin clapping against each other.
Feeling her pussy squeezing my cock as she's getting ready to have another orgasm while wrapping her legs around my waist Rias ( please don't stop fucking me I can't live with out this feeling anymore or without you please cum with me) she told me in between her moans listening to her plea I decided to give her what she wanted which is cumming inside her pussy as I pushed deeper inside into her pussy where I had entered inside of her womb while I continued to pump my cum directly into her.
Pulling out my still errected cock that was covered in our juices as I watched her breasts go up and down while she catches her breath William ( my dear Rias you think we're done here my libido is off the charts since I'm a dragon so I can go all night long) and with that I had shoved my cock back into her pussy that had jerked her awake due to the intrusion of me entering inside of her as she came onto the spot William ( this time I'm going to fuck your pussy and womb at the same time) I told her in a preditory voice.
Jackhammering her pussy as the tip of my head entered inside her womb which made Rias arch her back while I held her by waist going balls deep having Rias a moaning mass. Having her pussy started to cream as I drill into her pussy while kissing her womb with each thrust while her pussy started to fart and quive with each thrust of my hips. Feeling my balls swelling up and I unleashed another load deep within inside of her as she squirted for the fifteen times in the last hour. Pulling my cock out of her swollen pussy and once I did she had rolled onto her stomach.
When she did I saw her medium size bubble butt seeing it I couldn't but help but have a preditory smirk on my face licking my lips I get right in between her legs and lined my cock that was still covered with a mixture of our cum with her asshole William ( I'm going to claim your last hole as my own) and with that I shoved three third up Rias's ass that had woken her up from her unconscious state Rias ( your cock is to big and thick is entering my ass I can't take it I'm losing my mind) she told me while she clinching her teeth.
Pushing more of my cock up her ass as I take her anal virginity I begin to slowly move my hips as I started to fuck Rias in her ass as she started to moan and grunt in an animalistic manner soon enough I was going balls deep inside her ass pah pah pah pah the sound of skin colliding with one another as dominanted another hole of Rias Gremory deciding to let her get some rest I pushed one final time and creampied her asshole seeing her cum from having her ass fucked along with an happy smile on her face I couldn't help but smile and give her a gentle kiss on her forehead.
Scene Change Phoenix Territory Phoenix Manor Pov change: Right after William left both of Isabela and Yubelluna after telling them both that he was a Tru Dragon God they couldn't help but looked at each other in shock due to the relavation they both received Isabela ( hey Yubelluna do you believe his claim on being a Tru Dragon God)? She had asked her in doubt not believing in William's words Yubelluna ( I'm not sure but the aura that he gives isn't like Tanin who was once a dragon king but maybe Lady Cora would know about him since she's one of his mates).
Hearing Yubelluna's suggestion Isebela nodded her head in agreement as the two started to head towards Cora Phoenix's bedroom. Standing right in front of her bedroom door the two of them looked at each other before knocking on the door hearing a soft come in from Cora the two had walked in to see a smiling Cora Phoenix sitting on her bed. But seeing the serious look on their faces she had arrected an a silence barrier inside of the room.
Cora ( so I'm guessing that you saw him leaving my room and he told y'all something didn't he) she asked both Yubelluna and Isabela with an knowing smirk on her face Yubelluna ( is it true that William is a Tru Dragon God)? She had asked her while walking towards her which had gotten a one word from Cora Cora ( yes) but she continued Cora ( and before you ask yes I'm one of his mates ) she shamelessly showed both the surprised reincarnated devils her mate Mark Yubelluna's thought ( I think I've made a good choice of asking him for help) she thinks to herself while the room was in utter silence.
