Chapter 34

“Are you going to join me, Jason?” Karla said in a soft voice that could barely be heard above the running water. “Or are you just going to stand there and watch me?”

Karla turned away from Jason and faced the tiles of the shower wall. She leant forward while keeping her legs straight; parting them slightly as to show off her charms while at the same time looking back over her shoulder at him. Jason hungrily ran his eyes over her perfect body; from the way she was standing he could see everything.

“I don’t mind you looking.” Karla continued, her voice growing throatier as she allowed arousal to suffuse her face. “But I’m sure you would have more fun if you came in here with me.”

“How could I resist?” Jason said huskily, and covered the distance to the shower in a few long steps - opening the glass door and standing just at the entrance to the shower. He made eye contact with his teacher and was momentarily caught up in how intense it was. Her pale white skin was gaining a pink hue from being under the hot water of the shower and he could trace the muscles in her legs and thighs easily in her current stance. Even with him standing so close to her, Karla stayed in the same open and vulnerable pose; her could tell from her open and panting mouth that she was growing increasingly horny by exposing herself to him.

“Have I told you how perfect your ass is before?” Jason murmured. He reached out and trailed the backs of his fingers over the curves of her buttocks and hips - watching her shiver under his touch.

“You’ve mentioned it.” Karla gasped. She arched her back and clenched her ass-cheeks in response to him teasing her skin. “Something about all the students at school liking to watch me.”

“No one would ever believe me if I told them about this.” Jason smiled. He extended his index finger and ran it down between her buttocks - pausing on her anus and gently rubbing back and forth over the puckered ring of muscle. “That I’ve been in here.”

Karla gasped and shuddered again. Jason moved his finger further down and delicately stroked the silken folds of her pussy. Even under the running water he could tell just how wet she was. Wet for him.

“And in here.” Jason continued. He found her moist opening and inserted his finger smoothly up to the knuckle inside of her. “All the way in here.”

“Jason.” Karla whispered beseechingly. “Please...”

“What do you want, Karla?” Jason asked playfully. He wasn’t surprised that he was rock hard again - even so soon after cumming in her mouth. He started to slowly thrust his finger in and out of her pussy.

“Wouldn’t - ah! - you rather use something else other than your finger?”

“Like what?” Jason teased, enjoying playing with her. He added a second finger and started pumping them both in and out of her with an increased pace.

“You’re cock.” Karla said, making an effort and giving him their special half-smile even while her face was flushed red and twisted with arousal. “Wouldn’t you rather be inside me, Jason?”

Karla suddenly tensed her body and flexed the walls of her vagina - noticeably clamping herself around Jason’s invading fingers. It was Jason’s turn to get a little red in the face - he couldn’t help but imagine how it would feel to have her squeeze like that while his dick was in her.

“If you keep doing that, I will.” Jason said hoarsely.

“Oh is that right?” Karla said huskily. Her face went a darker shade of red with effort as she started to rhythmically clench herself around his fingers.

“Fuck.” Jason said softly.

“Yes.” Karla gasped out in between squeezes. “Please fuck me, Jason!”

Jason quickly pulled his fingers out of his teacher’s pussy and moved closer behind her. He closed the glass door of the shower behind him so that they were both enclosed within the confines of the small cubicle. He placed his hands on Karla’s rump before sliding them up over her hips to grip her by her narrow waist. Then, bending his knees slightly to get the right angle, he placed the head of his cock at the entrance to her pussy and started to push in.

“Yesssss...” Karla hissed as she felt him start to fill her up. She placed both hands up against the tiles of the wall and hung her head while pushing back with her haunches. “Fuck, yes stretch me out!”

“Jesus.” Jason cursed happily as he fed her more of his shaft. When he bottomed out in her and the soft globes of her ass was pressed onto his thighs they both sighed in pleasure. Then he started to fuck her in long smooth strokes.

Karla initially gasped and moaned as he worked his cock in and out of her depths, but soon there was a note of frustration that began to creep in. She groaned out encouragement and tried to thrust backwards to meet him in an attempt to make him fuck her faster, but she was stopped by the cramped confines of the shower. Jason for his part was happy to languidly fuck his teacher - enjoying her growing frustration and need.

“Jason” Karla whimpered. “Harder - fuck me harder!”

Jason didn’t increase his pace in the slightest - instead raising a hand and bring it down with a ringing slap on her right buttock.

Karla yelped and then shuddered at the unexpected strike. She turned around and gave him a look that was so full of heat and promise that it felt like it seared him. She then hung her head down again and futilely tried to fuck back onto his shaft.

“Please!” Karla begged. “Fuck me harder, Jason!”

Jason didn’t answer but instead gave her another slap - this time on the other buttock. His teacher shuddered and moaned again - something she repeated every time he struck her. Jason kept it up - when Karla asked him to fuck her harder he spanked her - and soon both of her cheeks were bright red with the marks from his hand.

He was beginning to feel the need to really give it to her, but he held off; a combination of enjoying this light power play between them and having a plan in mind. He quickly raised his finger to his mouth and covered it in saliva and then carefully placed it over Karla’s puckered anus. His teacher gasped at feeling him touch her there, and then gave a guttural groan when he started to push the digit inside of her ass.

It was a little tricky - keeping up the pace of fucking her pussy while fingering her ass - but Jason managed it. When he started to finger her rear in time with the thrusting of his cock, Karla’s moans got exponentially louder and longer.

“Do you like that?” Jason whispered hoarsely. He was getting a little out of breath.

“Yes!” Karla hissed.

“Are you mine?” Jason pressed her. He curled his finger while it was buried in her ass and she jumped.

“Yes yes yes!”

“Tell me then!” Jason groaned. He needed her to say it. It was time to make her his permanently.

“Yes, Jason I’m yours!” Karla cried out. Her fingers curled as she clutched at the wall of the shower. “Forever yours!”

All of a sudden - just as it had with his mother and aunt - Karla began to spasm wildly as she came - completely overcome and overwhelmed by the process of what was happening to her. She sagged on her feet but Jason was ready; reaching beneath her and locking his arms under her waist. She flopped forward and the only thing holding her upright was Jason’s grip around her middle. Her head fell down between her knees until she was literally folded over double. Jason grunted with the effort of holding her weight but kept on fucking her - her pussy was clamping down and rippling deliciously around his cock. She was like an insensible fuck-doll.

Jason fucked her as well as he could for a while - Karla was still out of it but she was beginning to make small little whimpering moans in response to his thrusts. Deciding to change things up a bit - as well thinking a little evilly that it would bring her back round - Jason pulled his cock out of her pussy and awkwardly manhandled his teacher’s limp body until her got in the right position. Holding her up with one arm for the moment, he lined up his dick and placed the swollen head at her puckered anus.

He knew that she wasn’t lubed up for him, but at the same time his cock was slick with her juices. And she was his - she had just made it so.

Jason grunted as he forced his thick cock into her tight rear opening. It was a little harder than it had been previously, but soon enough he was buried all the way inside her rectum. He shuffled them both forward until Karla’s back was pressed right up against the tiles of the shower - she was now sandwiched between the wall and Jason while still being folded over double and Karla couldn’t have got up now even if she wanted to. With the wall to brace her still limp body against, Jason could get more power into his thrusts - something he took advantage of with relish. He didn’t give her any warning - instead he started to hammer his cock in and out of Karla’s ass - gasping with the effort and pleasure of it all.
