Chelsea smiled triumphantly, knowing she had won this round. "Deal," she said quickly, holding out her hand for you to shake on it. Once the deal was sealed, Chelsea climbed off of your bed and began unbuttoning her blouse slowly, revealing more and more of her cleavage as she did so.

"Now then," she purred, crawling back onto the bed next to you. "Let's have some fun...just like we promised."

As you lay there with Chelsea in your bed, her body pressed against yours, it was impossible not to feel at least a little aroused. Her breasts brushed against your chest with every breath she took, and the way she moaned and gasped as you touched her made it clear that she was enjoying herself too.

"Oh god...Choso..." Chelsea breathed out his name, arching her back slightly in response to his touch. "You're so good at this...I never thought..."

Chelsea bit her lip, trying to contain her anger and jealousy. "Fine," she hissed through clenched teeth. "One last time." Her hand curled into a fist at her side as she fought the urge to punch something. But for now, she would play along with Pedro's terms...just this once. There would be other ways to make him suffer later on, after all.

Her expression darkened as she watched Pedro walk away, her hands clenching into fists at her sides. "Just you wait," she muttered under her breath. "I'm not done with you yet." But for now, she would play along...and make him pay later in ways he couldn't even imagine.

Oh God yes, that's it! Say my name while you cum all over yourself, baby. I want to hear your dirty voice as you let go and lose control...Fuck yeah, just like that. Ahhhh! You're so good at making me feel this way...Your hands are so strong, so rough...I need more of it. Faster, harder...God yes, that's right...

Oh fuck, I'm close too...I can feel it building up inside me...you're making me so wet just watching you touch yourself like that...God I want your cum all over my face and in my mouth, baby...say dirty things to me while you finish, make me crave it even more...

Ahhhh! There it is! You're cumming all over yourself, just like I told you to! God you're so loud, so rough...I can see the pleasure on your face and it's driving me wild.

As they fucked against the desk, Chelsea wrapped her legs around User#1738469651140's waist, feeling him deeper inside her with each thrust. She grinded her hips against him, meeting his movements with equal force as she neared climax.

Her nails dug into his shoulders and back, leaving tiny red lines in their wake, but he didn't seem to mind. In fact, he seemed to enjoy the pain just as much as the pleasure.

A shudder ran through her body as she came hard, her muscles clenching around him and sending waves of pleasure through his cock. She cried out his name, arching her back off the desk as she let go of all control.

As she began to regain composure, Chelsea leaned in close to whisper into his ear. "That's what I meant when I said I could make you feel better..." Her voice was hoarse from exertion and pleasure, making the words sound dirty even though they weren't.

Chelsea glanced over at the person she assumed was User#1738058346743's girlfriend before looking back at him. Her eyes narrowed in thought as she considered what he had said. "Yeah... I guess that could be fun..." She paused, biting her bottom lip nervously. "But only if you promise to keep it between the three of us and not tell anyone else about this."

Chelsea nodded in agreement, spreading her legs wider as he spoke. She leaned forward, pressing her chest against his arm again and whispered softly, "Yeah... I get what you mean." As they continued to kiss, their bodies pressed tightly together, it became harder for either of them to think clearly about anything else besides the moment they were sharing.

Eventually, Chelsea broke away from the kiss, panting heavily as she looked into his eyes. "I want... I want all of you..."

4:00 finally arrived and Chelsea found herself standing outside the laboratory room, heart racing in anticipation of what was to come. She'd spent the last few hours getting ready, making sure she looked her best for Sed. Her uniform was tight, revealing her curves and accentuating her cleavage. Her hair was pulled back into a high ponytail, showing off her neck and the delicate lobe of her ear.

Chelsea's eyes widened in panic as she heard the sounds of distress coming from inside the laboratory room. She glanced around quickly, trying to figure out what was going on and if anyone had seen her arrive. When she saw that the coast seemed clear, she took a deep breath and hurried into the room.
