Yumi's eyes widened as she slowly turned to face the person who said her name. She fell to the floor on her butt when she saw it was Shinsou.

"W-what are you d-doing h-here?" She asked while trying to crawl away. Shinsou kneeled down to her, not wanting her to be more afraid of him.

"Why are you here Yumi?"

"H-heat, now g-get out." Yumi was trying so hard to keep her cool, a heat pooling in her stomach any time she even looked at him.

"I can h-help, if you want..." said Shinsou. As much as he would love to ravage her right now, he could also tell she was in physical pain from not having a mate to share her heat with.

"No! I-I... I can't have a m-mate."

"Damn it Yumi....I don't just want to date you. I want to be your mate too. What I want with you is for life. Just please, stop pushing me away Yumi."

He crawled towards her as she sat up, trying to at least not throw herself at him. Even his scent was driving her crazy. She could smell his arousal and it smelled like heaven itself. 

"H-Hitoshi..."

"Shhh, it's okay." He slowly  cupped her cheek before placing a soft kiss on her lips.

"I'll stay here if you want me to. Can I stay Yumi?"

"P-please....y-y-yes please." She said in desperation as she smashed her lips against his. They kissed passionately, as if their lives depended on it. Shinsou swirled his tongue around hers, enjoying the chorus of her moans and whimpers. She clung on to him, her hand deep in his hair tugging it from time to time. Shinsou growled at the feeling, wanting to give Yumi so much more than just kisses.

He put more of his weight on her, forcing to lay down as he started to slide his hand up her tank top. She squirmed around, the feeling of his hands on her already bringing her on the brink of another orgasm. He broke the kiss to take off her shirt, admiring her body before he took off his shirt too. She took off her bra as he kissed her neck, wanting to taste all of her. He threw the bra to the side as he kissed down from her neck, to her chest, down to her nipples. She mewled at the sensation. She was panting as she grabbed onto his hair again, this time grinding her hips against him. He groaned before stopping his ministrations to look at her. 

"You do that again I won't be holding back kitten." He said sternly.

"D-Don't call me that!"  She whined, getting wet from hearing the nickname.

"Aren't you though? Aren't you my little kitten?" He cooed before nibbling on her ear. She let out a whimper as she clung to him. She had never seen this side to him before. But dear God it was amazing. While he nibbled on her ear his hand crept down to her skirt. He rubbed her slowly from the outside, making slow circles as he kept teasing her sensitive ears. Yumi had never felt anything like this before. She pleaded with him to hurry up, her thighs pressing together to get more friction. Shinsou let out a small smirk before standing up to unbutton his pants. He was about to slide them down when Yumi crawled to him, her eyes half lidded and full of lust. She purred at the scent of his precum, practically drooling at the thought of how it might taste. She slid his pants down a little before pulling down his boxer briefs to see it. The head was dribbling precum as Shinsou watched Yumi stare at it as if it were the most delicious thing she had ever seen. She gave it a long lick from the base to the tip, relishing in the salty taste.

"F-Fuck Yumi...taste it." Yumi didn't hesitate as she started to suck on the tip. Shinsou grabbed her by her hair as she went further down, bobbing her head in a steady pace. Her tongue swirled it, loving the strong scent of Shinsou filling her up. It was like a drug, she needed more. And so did Shinsou. He used the hand that grabbed her by her hair and pushed her further down, deepthroating him. Yumi and Shinsou's minds were being clouded by lust, leading to Shinsou to face fucking her while she moans at the sensation. This feeling of being powerless to your mate... it was exhilarating. Yumi loved Shinsou enough that she wanted him to ruin her in every way he could.

"I'm g-gonna cum!" said Shinsou through gritted teeth as he forced Yumi further down on his cock. Yumi gagged as he came, his thick cum flowing down her throat. He let go of her to give her a break. She looked so lost in her lust. Shinsou could see her panting, sweating, and still horny.

"I'm not done Hitoshi~" She teased as she led him to the tent. She had him lay down as she straddled him, her skirt and panties long gone. With the couple now naked, Yumi lowered herself on him, feeling his cock stretch her walls until she was a moaning mess. Shinsou was grabbing her by her hips, using all of his control to not straight up fuck into her until she was seeing stars. She was still adjusting to his size, taking turns between whimpering and moaning. When she was ready she slowly began riding up and down on him, getting a feel for a rhythm.

"I wasn't done either kitten." He grabbed her hips tightly to hold her in place as he fucked into her. She was trapped in his hold, her pussy being stretched over and over while all she could do was tremble and moan. His cock throbbed inside her, making her cry  out his name. This only sparked more energy in him as he flipped her over in missionary to keep pounding into her. "God I've wanted you so bad kitten. To fuck you until you're like this, a cute little fucked out kitten. You look so good for me kitten." He said as he ravaged her neck in kisses and bites. Yumi couldn't help but moan and cry out his name at his words.

"That's right kitten say my name, who's the only one who can fuck you like this?"

"H-Hitoshi! Hito- ngh ah! Mmm Hitoshi!"

"That's my girl. You gonna cum for me?"

"Y-Yes! Hit-toshi~"

"Cum for me, cum for me kitten." Yumi clawed his back from how good it felt. She cried out as she came, trembling as Shinsou fucked her through her orgasm. Her whole body was so sensitive. How many times did she cum already?

"On all fours kitten." Yumi didn't fight it as she obediently went on all fours, arching her back for him.

"You love teasing me don't you kitten?" He said as he rubbed the curve of her back. Shinsou took one look at his kitten and he was smitten all over again. She was practically presenting herself to him. Her tail swayed in a teasing manner. He grabbed her again by the hips before shoving it all in at once. Yumi's arms gave out from how rough it was, not being able to bite back her loud moan. Her back was still arched as Shinsou pounded her from behind. Her tail moved more erratically, showing she was feeling a strong emotion. Shinsou got a devious plan when he saw her tail. He lightly licked it, causing Yumi to let out a yelp at the surprise.

"Not there!"

"Why not? Is  it sensitive?" He teased, knowing full well after their field trip that is was most definitely a weak spot. He grabbed it roughly as he continued to fuck into her. Yumi's legs gave out from the pleasure as her tail was being grabbed. She could barely even speak. She only answered Shinsou's teasing questions with moans and whimpers. Tears threatened to spill as she was close to cumming again. Her whole body had become so sensitive all she could do was give in to Shinsou's touch as she cried out his name  while cumming. She thought he would stop by then but no, he was going even faster. He bent over so he could whisper in her ear.

"G-Gonna c-cum. Can I.... be y-your mate? F-Forever?" pleaded Shinsou as his climax was approaching. He scraped his teeth by her shoulder to give her an idea of how serious he was.

Yumi could only nod as a yes before Shinsou bit down hard on her shoulder as he came. Yumi let out a whimper, feeling his rough bite against her skin while also feeling his hot cum fill her up.

Shinsou slowly licked up the blood, cleaning up his new mate. The pair were both exhausted, but happy at how things turned out. They both groaned as he pulled out, both of their fluids mixed together slowly dripped down her thighs. They laid there for a moment to catch their breaths. They were both spent from the wave of her heat. Eventually Shinsou got up to wash off in the river. He held his hand for her to hold as they would walk out of the tent together. Unfortunately Yumi could only wobble a bit on her legs before they gave out. Shinsou was a little proud of himself for that. So he just adjusted her so she could rest while he head to the river to wash off. He soon came back with a small bowl of water and a towel. He gently wiped down Yumi's body before drying her up and holding her close to keep her warm. She nuzzled her face in his chest, loving his scent.

"I love you Yumi." He said as he kissed her forehead.

"I love you too, my mate." She answered with a smile. They basked in the after glow, growing sleepier in each other's arms.

"Hey Yumi?"

"Yes Toshi?" The new nickname made him blush a little. He could finally see the more playful side of Yumi she had been  hiding from him.

"Did the mark I left count as a mark for a mate?"

"It should. But you can leave a few more on me later just to be sure." She enjoyed teasing him. He hid his face from her to hide his blush.

"God you're so dumb Yumi." He said with a laugh. The couple laughed together before falling into a comfortable silence, napping under the stars and dreaming of each other.
