The blood at the top of Leon's finger activated. And following his innermost desire, it formed into a spell...
A spell that he didn't learn during his battle classes. Nor during his tactic classes. One that he didn't hear about even during his general magic classes.
It was a spell that Leon learned in history classes and developed from scratch all on his own.
Back in his original world, developing that spell gave him the highest score from a voluntary subject of spell recreation. And back then, he never even dared to imagine that this spell would one day come actually handy.
'A true faithfulness spell,' Leon thought, recalling the original name for the art he just used.
It was something that most of the population of his original world considered to be just an antique, something no longer applicable to the world where morals no longer supported the idea of only ever having a single partner. And as such, a spell that ensured one's faithfulness disappeared from the magic dictionary as something too nefarious to keep on existing.
But now...
The blood from Leon's fingers exploded outwards, covering every tiniest bit of Sarah's insides. Yet, rather than forming any complicated structure within the delicate part of her flesh, Leon's blood simply infused itself into her insides... And then started its long process of incubation.
There was only one way to activate it. And if during such act this blood would mix with an intruding flesh containing different blood...
"Whaaa...." the air escaped from Sarah's lungs as she slumped down. Her moist insides contracted all over Leon's finger, refusing to let him go even after he was done creating the seal of her insides.
"Are you okay?" Leon asked, holding the girl up by her most secret place for a second before he managed to sneak his left hand underneath her arms.
"I'm finnee," Sarah mumbled with her trembling lips. She then raised her moist eyes up, locking her sights on Leon's lips. "Can I..." she spoke, only to gulp down her saliva.
Her insides twitched, rubbing all over Leon's finger... Yet, as soon as they relaxed, Leon made the most out of the opportunity and snuck his finger out.
"Kiss..." Sarah muttered only to open her eyes wide and then raise them a bit, all for the sake of looking right into Leon's eyes with an ocean of disappointment, surprise, and unwillingness mixing at their bottom.
"Why?" the girl whispered.
She then pursed her lips and tightened her hands only to smack them lightly against Leon's chest.
"Why, why, why!" she asked, again and again, pushing herself at Leon so heavily she ended up breaking his stance. The two of them fell to the back, with only the bed saving Leon from potential injury.
The bloodmancer's back sank into the bedding so hard the bed frame uttered a small cry, proving it was right on the edge of breaking apart.
And yet, against all odds, the wood that the bed's frame was made off kept it together.
Only for Sarah to fall down on Leon's chest.
The wood cried out again, yet, against all odds, it somehow braved the ordeal, saving the couple a moment of the consternation of their bed breaking apart.
"Why did you pull your hand away?!" Sarah cried out while looking with her teary eyes straight at Leon's face.
"Huh?" the young man couldn't help but feel puzzled. "I completed the seal, so why would I..."
"That's unfair!" the girl screamed out only to slam her forehead against Leon's chest, hiding her face away from his eyes.
The bloodmancer was at a loss. He could tell that the girl was excited, but the idea of her throwing herself at him like that...
'Did I underestimate her horniness?' Leon asked himself, not sure how he was supposed to proceed.
Even though he wasn't a virgin... He never really went through the normal process that would lead others to cast away their first time.
"No one else will be able to lay their hands on me anymore, isn't that right?" the girl asked in a perfectly composed voice, raising her face to look at Leon's eyes. "Isn't that right?!"
"It is..." Leon replied, taken aback by the sudden change in the girl's mood.
"Then..." Sarah muttered the courage that propelled her change of mood running out as nervousness took over again. "Can't you at least give me something to look forward to?" The girl gulped her saliva down as she raised up, sitting right down on Leon's lap only to move her hips to and fro, rubbing her crotch against the bloodmancer's pitched tent.
"You know we can't," Leon attempted to argue, only to suddenly cut his words short and purse his lips. "No, you know this already," he said, lowering his eyelids a little as he took a deep breath and looked deeply into Sarah's eyes.
"Tell me," Leon finally spoke after calming himself down a little. "What do you want me to do?" he then asked, opting to go with the most reasonable route.
The girl knew they couldn't fuck. She said it herself. The only reason why Leon cast a seal upon her insides was to ensure she wouldn't be able to get pregnant with anyone unless learning how to and then proving to him she could hold her bloodline back.
And yet, she acted as if there was something that he was obliged to do.
'I've never been with a free woman, only with a whore whose job was to satisfy my every desire,' Leon thought, going back to the times when even his intimate part of life was subjected to the wishes and folly of his owner.
'So, as embarrassing as it might be for her, the only way for me to know what she wants...' Leon thought. And then, he opened his mouth.
"I don't really know much about this part of life," he said, his expression darkening a little as he recalled the unpleasant memories again. "That's why, if you want me to do something, you need to tell me what you want."
The girl's cheeks exploded with a blush.
At first, she averted her eyes while her body tensed up. Leon could even feel her insides contracting with the tip of his pitched tent that lodged itself right into her moist hole.
Then, Sarah brought her eyes back to Leon's. She gulped her saliva down and took a deep breath.
"Kiss..." she muttered, struggling to maintain eye contact. "I want you to kiss..."
'I already made her wait enough,' Leon thought. The fact that he had no idea what to do didn't make him blind to Sarah's reaction so far. As such, rather than subjecting her to even greater embarrassment and torturous wait, he reached out with his hand for the back of her head.
And then, with a gentle pull, he brought Sarah's blushing face closer before gently pressing their lips together.
For a long moment, Leon allowed his mind to fully immerse into the softness of the girl's wet lips. He thought of nothing else but the faint sweetness of her saliva and the soft texture of the tip of her tongue.
"Haaa..." Sarah's pulled her face away while releasing a long, satisfied sigh. A single strand of saliva hung down from her lips, connecting her to Leon's mouth.
Seeing the dazed expression on the girl's face, Leon couldn't help but smile.
The silly look on Sarah's face somehow filled his soul with a strange sense of satisfaction while filling his loins with fire.
"Then, I want you..." Sarah opened her mouth and attempted to speak, only for her cheeks to turn vividly red. She then averted her eyes, locking them on Leon's hand rather than his eyes.
As if to break Leon's perception of just how red one's cheeks could turn, Sarah's blush intensified even further right as she reached out and grabbed his hand.
"I want your hand..." she muttered, only to bring her own hand and rest it on top of Leon's pitched tent. "Down there..."
