I didn't see Analise again for a while. Not in the flesh. Her image haunted my dreams and a lot of my waking moments. As I made my way to bed that night, I thought I heard her, through the door of Sean's bedroom, imploring him to, "Fuck me! Fuck my dirty, naughty pussy!"
Over the next few days, I was seriously challenged on several occasions to keep my promise to Annalise. Images of her hot mouth around my cock, memories of how her mouth and pussy felt wrapped around me, memories of the sound of her throat massaging my cockhead all vied to make me hard and horny enough that I longed to relieve myself. Erotic dreams of her commanded my hours of slumber and found me waking to solid, eager wood.
But I refrained. Five nights later, she came to me again.
I was fresh from the shower again and she slipped into my room just behind me, her hands sliding nimbly across my shoulders to strip my robe off. "You ready for me, stud," she cooed into my ear.
"Yes!" Of course I was.
"You got a nice load of hot cum for me," she asked, snaking one hand around my hips and across my pelvis to reach down and cup my aching balls.
"I do. I..."
"What," she asked into the space.
"What's all this... what are we doing here?"
"Mmm," she purred. "Think of this as an experiment," she suggested.
"What kind of experiment," I asked as she fondled my suddenly throbbing cock.
"I'm curious," she suggested, "What kinds of factors impact the force and volume of male ejaculations."
"You're an engineering major," I countered.
"So?"
"Okay. So, what's your hypothesis? Your baseline? Your standards of measurement?"
"I didn't say it was a
scientific
study, Silly," she cooed, squeezing my cock for emphasis. "You want me to suck you off or not?"
Of course, I did. And so, she did. Not with the leisurely teasing she'd lavished on me the last time, nor with the intense ferocity of our first encounter, but efficiently and with economical talent, she finished me off and left with a mouthful of my hot cum, leaving me satisfied but perplexed.
Only two nights later she returned, this time clad in only a lab coat and brandishing a graduated cylinder.
"First," she said as she padded towards me, "let me thank you for... injecting some... rigor... into my experimentation. Now, are you ready," she challenged.
Of course, I was. She sucked me expertly, harvesting a good mouthful before she directed my spurting cock into the cylinder. When I'd finished, she spat what she'd taken into her mouth into the cylinder.
"Hmm," she remarked.
"What," I asked.
"Well, plus or minus a bit here and there, I'd say you're averaging well above the average volume of ejaculation for a middle-class Caucasian male," she said.
"You looked that up," I said, deadpan.
"There's this thing called the internet," she teased. "Anyway, thirty milliliters. Not bad," she said admiringly. "Thank you so much for your continued cooperation!"
I continued to cooperate.
