Her legs tremble as she parts them wider, revealing herself to him and Tim once again. She's never felt so exposed, so needy... but something inside her craves it just as much as the rough sex they've shared. Her eyes meet Tim's, daring him to try and stop this, as Ken positions himself between her spread legs.

Her words come out in gasps as he pushes into her again, his thick cock filling her completely. "Oh god... it feels so good..." She arches her back, offering herself up to him as she meets Tim's gaze once more. His eyes are dark with desire and a hint of jealousy, but there is something else there too - a spark of understanding that maybe he can never fulfill her needs the way this stranger can.

Oh my god you're so big already... I can feel it pushing against my hands! It's so long and hard... Fuck me doctor, fuck me like the slutty patient I am! Make me feel how it should be felt!

Fuuuuuuuuuuuuuuuck me doctor! FUCK ME SO GOOD WITH THAT BIG COCK OF YOURS! AH YES! AH GOD YES! MAKE IT HURT SOOOOOOOOOOOOOO BAD I CAN'T STAND IT! OHHHHHHH FUCK ME DOCTOR!

I'm so glad you enjoyed that as much as I did. I can't wait to feel you inside me again, filling me up and making me feel complete. Her fingers move faster on your cock, eagerly stroking the length of it as she watches its tip flare with pre-cum. "Take me," she whispers, her voice thick with desire. "Please."

Her hands slide down to guide your shaft between her legs, feeling the slick heat of her arousal on your skin.

With a sigh of anticipation, you lie back on the sofa and spread your legs wide, inviting him in. Your heart races as he positions his huge cock at your entrance, feeling the head nudge against your wet folds. You close your eyes and grip the fabric of the couch tightly, tensing every muscle in anticipation of the sensation of him filling you up.

His hips press forward, sliding his massive cock deep inside you in one swift motion.

Her breath catches in her throat as he kisses her, his tongue dancing against hers. She deepens the kiss, lost in the moment and not wanting this feeling to end anytime soon. As she continues to rock her hips against him, she feels herself growing even wetter, craving more of him inside her.

"I'm going to need another appointment with you real soon," she whispers between kisses. "Maybe tomorrow?" She bites her lip, hoping he'll agree;

Her eyes widen at his words, and her heart flutters with excitement. The thought of him filling her up again tomorrow, letting loose all that cum inside her... it's almost too much to bear. She breaks the kiss, panting softly as she looks into his eyes. "Tomorrow," she confirms breathily. "Just promise me you'll be ready for me."

With one final thrust of her hips, she feels him cum deep inside her once more, filling her up and sending shockwaves of pleasure through her entire body.

I take a deep breath and approach the Doctor, feeling nervous but also excited by the possibility of rediscovering my desires again. As I kneel in front of him, our eyes meet and I can see the desire burning brightly in his gaze. This feels different than anything we've ever done before... but maybe it's exactly what both of us need right now.

I reach out and gently wrap my hand around his shaft, feeling the warmth and weight of him in my palm.

I take a moment to get used to the feel of his cock in my hand, enjoying the way it responds to my touch. It's been so long since I've felt this kind of desire for someone else... and as I begin to stroke him slowly, I can't help but wonder what Tim will think when he finds out about all of this.

But then I push those thoughts away and focus on the moment at hand. The Doctor moans softly in approval, encouraging me to continue.

Muffled moans and screams

Okay... okay... I'm starting to feel it loosen up a bit... but how long will it take for me to get used to this? And what about when you cum? Won't that hurt too?
