Well, she tries to

Her eyes widened at his order. "N-no! I agree to pleasure you, but actual sex is off limits!" she cried out, crawling backwards towards the door.

Kostas just grabbed her and threw her onto the bed. "Remember the safety of your students professor... Offering your precious virginity for their well-being is a brave deed." he snorted.

Byleth looked around and noticed her sword leaning against her nightstand. She was currently pinned by the fat ogre of a man, but if she could crawl just a teeny bit towards the edge of the bed, she would be able to reach it.

While she planned for her possible escape, Kostas tore a hole in her pantyhose, right at her crotch, revealing her soaking wet pussy. "Don't worry," Kostas said as he caressed the insides of her legs. "I will be gentle."

"Don't you da- OOOOOOOH...?" Byleth said, but was interrupted as he penetrated her. Only the head had entered her, but she still felt excruciating pain spread out over her entire body. She wriggled and twisted, trying to break free, but Kostas continued to hold her firmly as he pushed more of his length inside her.

Byleth screamed, but she soon noticed they weren't screams of pain or screams for help. They were loud moans, that she sang out with her entire body as she was plowed by the dirty old man. The pain was mixed with pleasure now and it was unlike anything she had ever felt before, she felt a rush of bliss satisfaction as she came for the first time from another person. To silence her loud moaning, Kostas pressed his lips against hers, pushing his warty tongue inside her small mouth. The female professor couldn't even resist anymore, she numbly lay beneath the large man, letting him ravage her body completely. He was now pounding her, the motion echoing as he smacked against her plump butt cheeks. Byleth could do nothing but moan into the mans mouth as he explored it with his tongue.

As the pain faded, Byleth's eyes became dreamy. Her whole which was stiffened before, now melted. Now she was just soft clay to be formed by this strong burly man. Her legs locking around him, her hands caressing his chest, she now embraced the man, instead of trying to run away from him. Like she worked on his cock before, she now worked on his mouth. She sloppily made out with Kostas, sucking on his tongue, licking his teeth and exchanging saliva. His breath smelled like feces and rotten bodies, and she absolutely LOVED IT.....

The erotic kiss came to an end when Kostas suddenly pulled back, leaving Byleth with a dazed face. Her breath was heavy and she was drooling from the first make-out session she had ever experienced. Without giving her any break, he flipped her over with his strong arms and began ramming her doggy-style.

She never considered losing her virginity was a pleasure in itself. It was the act of throwing it away to this disgusting pig, just throwing all the pride she would ever have as a woman and human. That thought made her head misty, and she threw her head back as she came for the second time. Now that Kostas didn't shut her pretty little mouth up, Byleth had to do her best to keep quiet during her orgasm, But in the end it became a pathetic attempt as she desperately moaned through her gritted teeth.

"I'm gonna cum professor... I'm gonna cum inside you" Kostas grunted into her ear. His words made Byleth snap back to reality.

"NO!!! DON'T CUM INSIDE I BEG YOU!" she screamed horrified.

"Think of the students seeing you walk around with that big belly... Them gossiping which student made the adored professor with child. Only for it to be ME!"

Byleth cried as Kostas sped up his thrusting. The thought of him impregnating her, carrying his child, and showing of her pregnant belly to the students at the monastery filled her with fear. It was horrifying, but something deep, deep inside her also made her excited.

"AH!~ AAH! STOP! GET OFF ME, DON'T YOU DARE CUM INSI-" Byleth begged, but it was too late.

Pressing his whole weight into Byleth and the bed, Kostas exploded into her womb. Large amounts of fresh baby batter pumped into her body, filling her to the brim. Byleth could only scream as she shook with pleasure, her toes curling up at the euphoric experience.

For a long while, they just lay there riding out the excitement as they both catch their breaths. Until finally Kostas pulled out as he stood up. His warm fluid poured out of Byleth's opening, like slow running lava out of a crevice. Byleth was still twitching from her massive orgasm, her legs felt weak and she didn't think she would be able to walk within a couple of hours.

When she finally opened her eyes, she saw Kostas being fully dressed and was already about to leave. Before he left through the door, he turned around and said; "Now that I've left my mark on you, you're my **** until the end of days."

Confused and still drunk from the sex, Byleth drowsily looked down on herself, and she was shocked by what she saw. Right above her leaking pussy, at her pubic area, something was etched onto her skin that wasn't there before. A bright red glowing tattoo, in form of an ornate heart.

Support level between Kostas and Byleth went up
