She started to respond but cut herself short with a sharp intake of breath followed by a shaky release. Tristan wanted to switch up the rhythm of the vibrations but knew better than that. The rise and fall of her chest, the way her eyes could barely focus, and how she kept digging her fingers into the carpet let him know she had to be close and changing the rhythm would just throw her off. He’d teased her enough all afternoon, and Tristan was ready to see the faces she made as she fell apart. He left the settings as they were, coaxing Cosima to lie on her back. He lay on his side beside her, fighting the urge to slide his hand under her sweater so he could feel the warmth of her skin. His dick twitched, reminding him that Cosima wasn’t the only one being slowly tortured, but he couldn’t stop taking her in — each jerk of her body, the way tears crested in the corners of her eyes, the little moans she couldn’t fight escaping her mouth.

“Tristan,” she whispered softly. “Please.”

He was undone.

“More?”

She nodded sharply, and he navigated to the app so he could increase both sets of vibrations. He was rewarded with a shaky sigh, and Tristan couldn’t stop himself from capturing her small moan in his own mouth as he leaned over and kissed her. If he’d expected another gentle kiss, Tristan would have been surprised by the way Cosima attacked his mouth, tongue lashing instantly against his, lips pressed hard until she couldn’t keep kissing him any longer. He could feel the deep shaking in her body even as she tossed her head back and let out a small keening cry that went straight to his dick. He let her ride the wave of her orgasm until she begged him to make it stop. She pulled herself into a sitting position slowly and gingerly once he turned everything off and shot him a shaky smile. Tristan kissed her softly before bringing his lips to her forehead, wishing they could lie there a bit longer but knowing there were so many things left to do. He pushed himself to stand and reached out to her, pulling her to her feet, then hooked his hand behind her thighs so he could lift her. She squealed in surprised delight as he brought her to her couch.

“Gather your strength,” he teased. “Somebody said decorating a tree is a mandatory Christmas activity, and it takes work.”

“Give me a few minutes,” she said with a small grin. “I need to recover.”

“Let me run to the bathroom while you do that.”

Then before he could stop himself, Tristan leaned in and kissed her forehead again. Damn. Could he really be that far gone over someone he’d almost literally just met?
