With that, he started pushing inside slowly but firmly, letting Jenna adjust to the unfamiliar stretch before fully seating himself inside her.
She moaned around Alex's cock at the intense fullness, eyes watering from the slight burn of the intrusion.
"Fuck, she's so tight," Dean groaned, hips twitching as he fought the urge to pound into her. "Gonna ruin this little ass..."
Jenna could only whimper in response, overwhelmed by the dual sensation of having them both inside her at once.
Alex started thrusting shallowly into her mouth as well, using her mouth for his pleasure just like Dean was using her ass.
They found a steady rhythm quickly, fucking into Jenna from both ends until the room was filled with nothing but grunts and moans of pleasure.
Dean reached around to rub Jenna's clit as he fucked her harder, sending sparks of pleasure shooting up her spine.
She could feel herself tightening around him in response, getting closer and closer to orgasm with every thrust of their hips.
"Gonna come," Alex panted suddenly, hips jerking erratically into Jenna's mouth. "Fuck!"
He came hard with a strangled cry, pumping his release down Jenna's throat. She swallowed convulsively around him, moaning as the taste of him coated her tongue.
Dean groaned at the feel of her tightening around him and followed quickly after, slamming in balls deep and grinding his hips against her ass as he filled her up with his own release.
"Fuck yes," he growled as he emptied himself inside her. "Take it all, baby. Gonna plug this ass up so you're full of my cum all night long..."
Jenna could only sob brokenly as she came apart between them, writhing and shaking with the force of her orgasm.
They collapsed together in a sweaty tangle of limbs afterwards, breathing hard as they came down from their highs.
Dean pulled out first with a wet sound and grabbed something from the bedside table. Jenna felt him pushing a hard plug into her tender hole a moment later and shivered at the unfamiliar sensation.
"There," he said with satisfaction, patting her ass lightly. "Now you'll keep my cum right where it belongs."
Jenna flushed at that but didn't protest, still feeling dazed and boneless from the intense fucking they had just given her.
She could hear Alex and Dean murmuring to each other quietly behind her, but couldn't quite make out what they were saying over the pounding of blood in her ears.
After a few minutes, Dean extracted himself from the tangle of bodies and stood up.
"I'm going to go grab a shower," he said bluntly. "You two can stay here if you want."
He didn't wait for a response before striding naked out of the room, leaving Jenna alone with Alex for the first time since they had started this...
Alex shifted beside her and cleared his throat awkwardly. "So..." he said hesitantly. "That was...intense."
Jenna laughed softly and rolled over to face him, noticing for the first time how red and raw his own cock looked. "You can say that again," she agreed wryly.
They stared at each other for a long moment before Alex shook his head ruefully. "I can't believe we just did all that in front of you," he admitted sheepishly. "I'm sorry if it was too much. You probably think I'm some kind of freak now..."
Jenna reached out to cup his cheek gently, stopping his apology short. "Hey," she said softly. "Don't apologize for what you like. There's nothing wrong with having kinks or needing dominance in the bedroom."
Alex looked at her searchingly for a moment before nodding slowly. "Yeah, I guess you're right," he agreed quietly. "It's just not something I've ever really talked about with anyone before."
"Well, I'm glad you felt comfortable enough to be yourself around me," Jenna replied honestly. "I think it's really sexy how easily you submit to Dean and how well you take his dominance."
Alex blushed at that and ducked his head shyly. "Thanks," he mumbled. "He really is my owner. Has been for a long time now."
Jenna's brows furrowed at that statement, but before she could ask for more details, Alex sighed heavily.
"We should probably get cleaned up too," he said tiredly, already sitting up. "Don't want to keep my master waiting."
Jenna nodded even as her heart clenched oddly at the title. Master...it sounded so intimate and final. But she had a feeling there was a lot more to Alex and Dean's relationship than met the eye.
Still, she pushed those thoughts aside for now and sat up by herself, stretching gingerly. Her body ached deliciously in all the right places.
Alex helped her up off the bed, and they made their way to the en suite bathroom together, washing each other down with efficient strokes under the hot spray of the shower.
By the time they finished cleaning up and got dressed again, Dean was already back in the bedroom, lounging on the bed in nothing but a pair of black sweatpants slung low on his hips.
He looked up as they entered and smirked knowingly at their freshly showered appearance.
"Feeling better?" he asked silkily, patting the space beside him on the bed invitingly.
Jenna hesitated for just a moment before crossing over to climb onto the bed beside him. Alex was only a step behind her, settling on Dean's other side.
Dean wrapped an arm around both their waists possessively and pulled them close until their bodies were flush against his.
"So," he said conversationally, playing idly with Jenna's damp hair. "What do you say we have some fun today? Show our girl here what else we can do together..."
Alex shivered against Dean's side at that suggestion and nodded eagerly. "I'd like that," he agreed shyly. "Want to see what other toys we can use on you, baby..."
Jenna swallowed hard at the dark promise in their gazes, feeling herself growing wet again already at the thought of being used by them once more.
But first...she had some questions she needed answered about their unusual dynamic.
