Summoner: Monster Girl Harem!

'No, what is this? I need him… I must have him? Are these my true thoughts?'

(Vincent POV)

I had just shot a load of my semen into that zombie woman's stomach. The pleasure that dominated me had faded, returning to normal. Her naked body was lying on the floor, making spasms. 'Why couldn't I resist her? Was it because of my lack of experience? Why do I feel so angry and frustrated?!'

There was a feeling of eureka when the familiar female voice sounded. I had almost forgotten about this system, as it wasn't a factor once I'd started training solo. Raizel was silent and returned to a red wisp entering my body the moment the woman began seducing me.

[Demonic Choice Unlocked]

1. A shallow pact with the woman. Discard her when she loses worth.

2. Kill the woman and absorb all her power. Ruthless yet a valid path of Wrath.

3. Show this woman what it means to incur your wrath. Dominate her in the field she specialises in make her squeal your name!

'Lets mess this bitch up. I am not some pushover! She has taken a taste of me, so let's devour her whole in return!'

I pondered how to punish her the most. Then the image of my full sin form came to mind her mouth could adapt to my cock easily, so couldn't her pussy? The system read my intentions and started giving me certain rewards now.

(Vincent POV end)

His body swelled up instantly now over 300 cm tall (9ft 10 inches) His body over double her size as his eyes peered down at her. Rage dictated almost every cell of his body, but his body seemed to find another way to calm his anger. She was the first to approach him so forcefully. She felt very special to him!

'I want her to enjoy this too… Even if it's making her submit! Mother said to treat girls well…'

The other girls who teased him were nothing close to this. He didn't wish to make her regret their first time as his massive hands groped her plump ass grasping her flesh completely as they sank in a loud moan of delight coming from her mouth as she swayed her ass against his hands savouring the pleasant feeling of his warm hands.

'Ah… that sensation is back… It's sooo much more intense! Oh god!'

Celine shuddered violently from his touch. Since she teased him, her pussy had been soaking. Her excitement and horniness only grew worse the more time she spent immersed in his scent. Her eyes were no longer red but mutated into a golden colour as her ass raised even further into the air.

"Mmmm go on! You have my permission, big boy! Show me just how amazing you are, Huhu!"

'Hmph! Take the high path while you can!'

'Ah… I cannot wait! If his feet grew this much, then…. Argh no! don't lick there!'

"Wait!? Don't lick my ass! Don't look at my asshole!"

He spread her ass cheeks with his massive hands. Her pussy lips parted, showing her soaked, clammy insides, which ignited his lust, causing his ogre like cock to throb. Vincent's tongue was massive now longer than 30cm as he slid along her thighs, which left a trail of thick saliva packed with Anima. This caused Celine to feel extremely sensitive and heightened pleasure.

"Mmmm! It tickles!"

Vincent traced along her ass, coating her lower body in his drool. Her body constantly buckled when he touched her flesh again. His tongue never came close to her pussy, only teasing her just as she did to him. Tears filled her eyes as she desired a complete release, but was too proud to ask.

'Fuck me! The first time in decades, a male can actually mate with me!'

His tongue teased her prepuce. The fluids oozing from her pussy mixed with his drool forming a sweet yet sticky honey apple like taste. His gigantic tongue could lick her entire vagina from her asshole to the mons pubis with one lick. He swirled his tongue around her labia; the force causing her to quiver physically with joy whenever he hit her clitoris. His tongue's tip teased her lips, parting them to as he tasted her sweet honey, enjoyed its ripe taste. He then moved upwards, wanting to coat her glistening began in his saliva.

'This isn't love, I know! I don't care about that. This woman must be mine! She is too charming to give to someone else!' He thought as his hands grasped her soft fleshy hips built for childbirth.

Her body felt wonderful. His tongue could touch all parts outside her vagina with a single movement. Its pleasing fluid spread along her labia, clitoris and began entering her entrance bit by bit. This caused her mind to blank out with each of his successive licks.

She couldn't make a proper word, as only moans and gasps came from her mouth as her body jolted each time his tongue teased her ass. Celine had never done this act, and it was extremely shocking as her body spasmed. The seeping pleasure clouded her thoughts and his scent driving her crazy.

'Ah…. It's there…. I need him to break this cursed body! make me a toy only suited for him!'

'NO! This is for my sisters and the future of my race. I cannot falter in passing pleasure!'

Celine took a deep breath in anticipation as she felt his large body move. She could feel something as hard as iron rubbing against her entrance. It was thicker than her arm. Her pussy felt slight pain as it slid inside, stretching her hole further with each inch.

Vincent began slowly thrusting into her dirty, wet cunt. The squelch was so loud it sounded like another filthy noise, causing her to blush as mature as she was. 'So embarrassing! But his cock gets harder each time! Does he like those noises? Pervert…' He enjoyed the sound of her fleshy ass slapping against each other and his pelvis when he slammed into her.

*Pah*

'Oh god! What is this? It's bigger than my arm…. FUCK! it hurts… but this damned body… Why is it turning into pleasure? I hate this pleasure! What if it wasn't this boy who still takes my feelings into consideration despite being filled with anger towards me?'

*Pah* *Pah*

"Mmph! Argh! Nnn! Wait…. Vincent! Ohh! deeper… slowly… I'm being skewered!"

Desire filled his face as pleasure overtook him. Her insides were extremely hot like fire and filled with sticky fluids, which wrapped around his cock as he pressed deeper inside the tight fit. She had a strange body that was like slime. It was rigid at first. His cock was so restrained the blood felt cut off, however after several thrusts it felt soft, gooey and welcoming to him.

*Pah*

"Mmn! Ahn! Fuck, this is nothing like sex with humans! Ahn pound me harder! Mmn~,"

Celine no longer thought about the contract, nor what the future held. She only thought about his cock and her endless climax. Her fat ass began slapping against his body with a loud noise. Countless sticky juices flooded out from her hole. This soaked both of them and caused several gooey strings to form from their pelvis and ass, joining them at the hip as the two thrusted against each other with passion.

"Mmn! It's getting thicker! Are you going to impregnate me? Yes! Ahhnnn fuck me! This dirty little bitch empress is like a puppet!"

*Pah* *Pah*

Her words no longer made sense, as only sex and pleasure filled her mind. She twisted her hips each time he penetrated into her. No matter how much it stretched with her climax, he could still reach her deepest parts.

"Ahhn! A place that nobody reached in either of my lives! Vincent! Vincent! Mmn! I'm… Oh God!"

She bit into her arm to stifle her cries of delight and the noise of air being forced from her chest after his powerful hips slammed into her ass. Her eyes saw countless golden eyes peering from the doorway. It excited her many sisters, who watched the two people's actions. They wished to join, however, knew it was impossible in their current state.

'I can't think straight anymore…. Why did you have to be perfect?'

"Ahn! Fuck! Deeper pound in my womb! Flood me with your sperm!"

'Please don't betray me! I don't want to lose everything again!'

The sea of pleasure also contained the small fragments of her fears. The betrayal of her closest friend left a scar on her heart. She couldn't trust men and only wished to use them as business partners or tools. Vincent scared her as his scent and charm seemed to penetrate even that defence without him even knowing.

*Pah*

Vincent was now gaining full control of his form, a very wonderful side effect of this sex. He grasped her large breasts from behind and lifted her up like a doll, turning her body to face him. Her eyes were now glowing golden, a look of complete satisfaction filling her face.

His lips approached Celine's beautiful peach lips naturally as their passion towards each other exploded. She was very skilled with her tongue from her previous life's experience as she sought him by coiling and entangling him. Her mouth now flooded with their honey apple flavoured saliva mix. Celine savoured his sweet apple like taste as drool began staining her mouth once again.

"Mmn! Chu! My womb aches! Ahn! Nnnph! Vincent! Chupa!"

*Pah* *Pah*

Her legs wrapped around his body, pressing his cock even deeper. She couldn't fit everything despite being inhuman however, it filled her like nothing before. His breathing became more irrate because of the intense kiss and her twisting hip thrusts. She felt his cock throbbing more and more than his arms. Grabbing her back tightened as he bit into her throat, violently drawing two thick streams of blood.

"Ahhhhn! Ohhh, I can feel it! Your warm sperm is flooding my womb! Mmmmmn Vincent! Nnnnn! Don't stop keep thrusting! Ahn! Mmmmph! Yes!"

*Pah* *Pah* *Pah*

She could feel his warm seed filling her body with each thrust. He was not following his instincts, still biting deeply into her neck. The pain hurt extremely, however; she felt a greater pleasure as if he was burning his ownership inside her womb and neck at the same time. His hot seed left her stomach slightly inflated with its substantial amount.

'Fuck….. I can't think… He… So much!? What if I really get knocked up!'

*Pah*

His thrusts finally slowed as a large amount of his creamy goo dribble out from her stretched hole as his cock softened a little. Her pussy made a glupe sound that caused the watching girls to blush deeply.

'Where am I?' she thought in a completely dazed sensation.

Vincent held Celine in the air as she lost all power after his orgasm. He only noticed her body shudder constantly with each thrust. Her eyes were now dazed and stared towards the roof. However, her hands softly stroked his back with a small amount of power.

'I can feel the contract being formed…. He is my master… He is my sister's master… Will he accept us? The race despised by the gods? Will they betray me once more? Can I live again if I lose this boy? No! this man's pleasure?'

Her eyes returned to a slight focus as her body slowly changed, growing two horns and a sharp tail. She looked into his eyes and saw that they were blank. He just seemed to be curious about her change and the fact he could feel a sort of control similar to his summons.
