I walk into the clinic room, my curvy frame barely contained by these tight scrubs and short skirt. The chubby man in his 50's is sitting there, naked and waiting. His eyes widen as he takes in my ample chest and ass. I smirk, knowing exactly what he's thinking.

"Alright, sweetheart," I say with a sly grin. "I'm here to help you with your little sperm sample. And trust me, I'll make sure you fully enjoy my assistance for the next 30 minutes."

I can see the excitement in his eyes as I saunter over to him, my breasts bouncing with each step. I stand in front of him, leaning down so he can get a good view down my top.

"Now, let's get started, shall we?" I purr, my voice dripping with sultriness.

I reach out and take hold of his older cock, feeling its plumpness and weight in my hand. I give it a few teasing strokes, relishing in the way it responds to my touch. My fingers dance along the length, tracing the veiny ridges that run along his shaft.

"Oh, baby, you've got a nice piece here," I say, my voice low and seductive. "So thick and long, just the way I like it."

I move closer, my face inches from his cock. I can smell the musky scent of his arousal, and it sends a shiver down my spine.

"And those balls of yours," I continue, my voice filled with desire. "So big, so heavy. I can't resist playing with them."

I cup his fat nut sack in my hand, giving them a gentle squeeze. I feel the weight of them in my palm, the sensation making my pulse quicken.

"Fuck, they're just perfect," I moan, unable to hide my own arousal.

I continue to stroke him, my hand moving up and down his shaft with deliberate slowness. I can see the precum glistening at the tip, and I lean forward, flicking my tongue against the opening slit.

"Mmm," I hum, savoring the taste of his precum. "You taste so damn good, baby."

I pull back, a mischievous glint in my eye. I lean in close to his ear, my lips just barely grazing his skin.

"You know," I whisper, my voice filled with wickedness. "I had this patient before, just like you. And let me tell you, things got real dirty in here. This older patient come in for a prostate exam. I could see the anticipation in his eyes, so I decided to give him a little extra attention. I slipped on my latex gloves, all the while feeling my nipples getting nice and perky, and started massaging his prostate with my skilled fingers. Damn, he was moaning and squirming with pleasure. And just when I thought it couldn't get any hotter, bam! He erupted like a volcano, shooting his thick load right on my face."

I describe in vivid detail a second encounter I had with another patient, painting a picture of pure debauchery. I watch as his excitement grows, his cock twitching in my hand.

"A hot summer day, sweaty bodies, and a certain patient with a monster of a cock. He wanted a taste of my thick ass, see? So, he spread my cheeks wide open, his thick trunk stretching me out so damn good. Let me tell you, darlin', I walked around this clinic with a limp, feeling that ache between my legs, a constant reminder of the pleasure I had. Goddamn, the things I do for satisfaction."

Finally, the moment I've been waiting for arrives. I grip his shaft tightly with one hand, while my other hand squeezes and massages his balls. I pump his cock with an aggressive rhythm, my movements fueled by a primal desire.

"Fuck, baby," I growl, my voice filled with raw lust. "You're gonna cum so fucking hard for me."

I can feel his orgasm building, his cock throbbing in my hand. And then, with a powerful surge, he explodes, his ejaculation slamming against the cup.

I admire the swirling, hot ejaculate, commenting on its obvious potency and virility. I bring it up to my nose, pretending it's part of the exam, but in reality, I can't resist the intoxicating aroma.

"Oh, I'm so sorry," I gasp, pretending to be shocked as I accidentally drop the cup, spilling his precious seed onto the floor. "Let me clean that up for you."

I get down on all fours, my skirt riding up to reveal my bare naked ass, jiggling and waving in the air. He can see my puckered asshole and my clean-shaven pussy, dripping with anticipation.

I delicately lick up the spilled sperm from the floor, my tongue darting out to catch every drop.

"Fuck, this tastes so good," I moan, my voice filled with hunger. "Not a single drop should go to waste."

Once I've cleaned up the mess, I turn back to the man, cum dripping off my chin. I smirk playfully and apologize.

"Oops, my bad," I giggle. "Looks like I need another sperm sample from you, baby..."
