I couldn’t help but notice that she was showing a lot of cleavage for a nurse. It took an extra second or two to sign my name at the bottom of the donation form as my gaze danced across the smooth skin of her breasts and the stress marks of her tight blouse between them.
Sara, her name engraved into a tag pinned to that stretched fabric, looked at me with her big, brown eyes and smiled. Her dyed-blonde hair fell over her shoulders and led my eye back down to her breasts. She leaned forward winked at me.
“Are you finished with the paperwork, Mr. Jameson?”
I felt my face flush as I looked back up at her. “Um, yes. I’m finished.”
Sara took the forms and disappeared into the file room for a moment before emerging again. Her walk was sensual, a full figure that swayed and bounced as she moved. She knew how sexy she was, and the way she looked at me and smiled yet again told me she knew that I noticed.
“The room is free right now,” she said, handing me a little plastic cup. “There’s pornographic material in there if you need it, and a non-spermicidal lubricant. Feel free to take your time–the more, the better so that we can get the best sample.”
She winked at me again as she said that last part, with a quick glance down my body. Was she flirting with me? As I walked down the hallway, I felt the bulge in my pants already starting to grow at the thought of that. This was going to be easy.
The room looked like a normal doctor’s examination room, but with a television set and a remote wrapped in plastic like a condom. I flipped through the available porn options, but nothing was anywhere near as interesting as the thought of Sara the nurse and her bouncing cleavage, so I flipped it back off, unbuckled my pants, and lubed up.
All I could see in my mind were those glorious tits, pressed together inside of her blouse. They were a little tan, with a porcelain smoothness that looked like they would be silk to the touch. I thought about squeezing them around my cock, feeling her nipples brush my thighs as I slid between them and covered her face with my cum.
“Oh God, Sara.” It was louder than I meant, but my orgasm was already building as I held the top of my cock over the little plastic cup. “OH GOD. SARA, I’M GOING TO CUM.”
“Excuse me, Mr. Jameson,” came a voice as I heard the door open behind me, “but you forgot to fill out your–”
“Oh shit,” I said out loud as I turned to see Sara and struggled to cover myself. “I thought I was supposed to go ahead and get started. I was just–”
“Sorry,” she said with another smile as she looked deep into my eyes. “You forgot to fill out one of the forms.”
She held my gaze with hers for several seconds before setting the piece of paper on the counter next to the door. My cock, having come only an inch from a full orgasm, was throbbing against my leg and dripping precum. Sara licked her lips and walked toward me.
“Informed consent is very important to me,” she said as she crossed the space between us. “If you’re not comfortable with this, just say so.”
I was silent.
She raised her eyebrows slightly and parted her lips like a blow up doll while she began to unbutton her blouse. “I find that the quality of sperm is better if I assist.”
She dropped to her knees and as she revealed her delicious, full breasts in a pink, lacy bra. She pressed them together, smashing her tit flesh together and making her entire chest jiggle, and looked up at me. “You’re sure this is alright with you?”
“It sounds…it sounds great,” I stammered.
She took the bottle of lube and reached into my pants, pulling my cock out again. My whole body jerked at her touch as a little wave of pleasure flew through me. She squired the lube between her breasts and rubbed it up and down her cleavage, then lifted them and slipped my cock underneath the lace of her bra.
“I want the highest-quality sperm from you that I can get,” she said, “so I want you to do something for me. I want you to stay relaxed. Don’t try to hold it back, even for a second.” She slid her tits up and down, slowly mashing them together as they engulfed my cock. “Just experience this and let it go naturally.”
She held my gaze with her eyes and pouted. At the sight of those luscious lips, I could already feel my orgasm building. Usually I would start holding back now, until I burst, but I tried to do what she said. She slowly ran her tongue along her lips as thrills of sensation made their way up my stomach and I began to hump her cleavage with more intensity.
“Don’t hold it,” she said. “Fuck my tits and give me every drop.”
“Oh my god.”
Her eyes widened and shimmered in the exam room light. “Give me every drop.”
I glanced at that delicious cleavage again and put my hands on her breasts next to Sara’s. They were perfect, more than a handful of plump porcelain that even spilled out beneath the cups of her bra, and my cock glided through them with every thrust.
“OH MY GOD, SARA.”
“Do it,” she said, her eyes almost on fire. I felt hypnotized by her gaze and couldn’t take it anymore.
I felt my cock spasm as I shot my first load onto her neck. It dripped back into her cleavage and she mashed her breasts together harder as I cried out and shot again and again. Her eyes were even more beautiful and inviting as I nearly collapsed on top of her before catching my balance.
“That’s a good boy,” she said as she pulled her tits away from my cock and put the plastic cup to her cleavage to collect the sample. She meticulously cleaned her breasts. “That’s perfect.”
She stood up and walked over to the counter, setting down the cup and twisting on the lid. I sat down in the examination table and tried to catch my breath.
“That was hot,” I finally managed.
“Was?” she said with a grin as she turned around.
Before I could protest, she was on top of me and her mouth was pressed to mine. Aching, my cock made its way to attention and she had her panties off almost before I knew what was happening. In another instant, those eyes locked on mine and she slid me inside of her.
“Cum for me again,” she growled. “I want that fucking cum.”
Her breasts pressed against my chest and she humped me wildly as she kissed me. Her perfume was an intoxicating, sharp smell that took my mind hostage and that dyed-blonde hair draped around my face so that I couldn’t see anything but her.
She opened her eyes and pulled her face back just a little, her lips brushing against mine as she whispered. “Cum inside of me. Don’t hold back.”
“Oh God.”
“Please cum inside of me.” Her eyes were locked on mine and stared deep into my mind. “Give me more.”
“SARA!”
She moaned out loud as I shot my sperm into her. I writhed and pumped my hips, jackhammering my cock up and into her as she kissed me again. When my throbbing cock had finally given all it could, she slowly ran her tongue along my lips and giggled.
“Your next appointment is in a week,” she said as my spent cock slipped from her dripping pussy. “Don’t be late.”
