Tanya Tests Again: Reliability Test

The next morning I woke up at 7:30am to my phone ringing. I picked it up and answered groggily "Um, hello? W-who is this?"

The chipper voice of the woman from the testing agency replied "Tanya? I'm sorry if I woke you up. We have a male tester that came in for a condom resilience test, and the testing partner, well, she isn't available."

I asked "Isn't available? What do you mean?"

The woman replied "Well, apparently, she said he was too big and she couldn't handle it. The doctor thinks you would be a good partner in this test. Are you available? Remember, it pays double, so $200."

I bit my lip. $200 was a lot of money. But how big was this thing that is scared a tester away? I replied "Well, I guess I can come in. I haven't showered yet, and I just got up, but I can be there in 20 minutes. I'll have to grab an Uber though. The bus would take forever."

The happy voice replied "This is wonderful Tanya. Thank you! We'll cover the Uber fair."

Twenty minutes later I was walking into the non-descript building, still looking like I had just gotten up. My hair was pulled back into a messy bun, and I was wearing a pair of grey sweats. I hadn't bothered to put underwear on under them given what I was here to do.

Dr. Morganson greeted me as I walked in. "Thank you, Tanya. We really appreciate this! I know you're probably a bit apprehensive as this is your first condom reliability test. Do you want me to sit in to make sure you're ok?"

I smiled a bit at her concern. "Yes, that would be nice, if you don't mind Dr. Morganson."

She nodded and led me back to a testing room. "Why don't you go ahead and get undressed, and I'll go get Dwayne."

I slipped the sweatshirt over my head and set it on the chair along the wall. My sweatpants followed, leaving me nude. Just then Dr. Morganson came back in with a man that I could only describe as chiseled from stone. He was immense and muscular. He seemed to be in his late 30s, though it was hard to tell for someone so fit. He was wearing boxers, but he quickly dropped those after he came in.

My eyes opened wide in shock. His cock was massive. It was soft, but it looked like it was 6 inches long, even in that state. And it was so thick. Even in its flaccid state it seemed to be almost as thick as my petite wrist.

I must have stared it with a shocked look for a while because I head the doctor asking softly. "Tanya, are you ok? Think you can work with it?"

I swallowed and nodded slightly "I, um, yes, I can give it a try doctor." I tried to sound confident, but I must have failed miserably as I heard Dwayne ask "Doctor, I thought you said she could handle me. It doesn't seem like she's up for it."

The doctor gave him a reassuring smile. "She'll be fine Dwayne. I've tested her, and I know she can do it. She just needs to realize it. This is her first reliability test."

I shook my head to clear my thoughts. "Yes. Let's give it a go."

I heard Dwayne chuckle bit and say "Well, looks like you might be looking forward to it." I followed his gaze and saw that my nipples were hard and erect. I blushed a bit.

The doctor interrupted and handed us the testing envelopes. We opened them and reviewed the conditions. It was a pretty simple test. We were to test the condom until the male tester ejaculated, and the test was required to last at least 10 minutes of insertion time. Position unspecified. The one thing that surprised me was that it stated that the male tester was required to maintain a pulse over 150 for 5 continuous minutes.

Dwayne put a pulse monitoring strap around his chest and set the watch portion of the pulse monitor next to the bed where he could see it. He looked at me and asked simply "Ready to get started?"

I swallowed and nodded as I reached out and wrapped my hand around his impressive cock. I started to slowly stroke it, smiling up at him, saying nothing. His hands moved to my breasts and cupped them, squeezing them gently. He asked softly "You're sure you're ok with this? Not many can take it. The other woman this morning started crying when she saw it."

I blushed but nodded my head yes. "I'm certainly willing to try. And as you observed, it gets me going just thinking about."

He smiled a bit and slipped a hand down between my legs. A finger ran lightly over my mound, eliciting a gasp from me. He grinned "You're wet."

I blushed but smiled, nodding. "You'll still have to do slow and let me get used to it though."

He nodded and looked down, his cock still only part way hard. Without either of us saying a thing I got down on my knees and took the head of his cock between my lips. He groaned "You don't have to do that. I can get myself ready."

I shook my head no and started to suck on the head of his cock, slowly taking more of him in, looking up into his yes. I realized I hadn't even thought about it, but he didn't have a condom on yet. The doctor didn't stop us though, so I continued.

I pushed down, taking more of him into my mouth as his cock slowly grew and stiffened. He wasn't fully hard yet, and he was already stretching my lips. How was I possibly going to be able to take him?

He stared down at me as I sucked on his cock, getting at best a quarter of it in my mouth. My lips stretched painfully, and I could feel the fat head of the cock against my throat. And yet he just kept getting bigger and harder. I stared up at him, my eyes watering from the effort of getting it into my mouth.

He smiled, looking down and pulled his cock back, pulling it out of my mouth with a loud pop. I stared at it in shock. It looked more like a baseball bat than a cock, a baseball bat that was about to be shoved up my pussy. I muttered "Holy shit..." without thinking.

He asked softly "Think you can take it?"

I blinked, swallowing hard again. "I.. I don't know, but I want to try."

He smiled a bit at and suggested "Why don't you go on top to start. That way you can control the depth and pace while you get used to it." I nodded and watched as he rolled the condom onto his cock and then laid down, his massive cock laying on his stomach, not quite fully hard. The condom was clearly stretched pretty badly to make it around his cock.

I climbed on the bed and positioned myself above him on my knees, my body perched above him. Reaching down, I took his cock and lifted it. Even in that position, the head of it rubbed against my pussy. I bit my lip and moaned softly, rubbing the giant head of his cock against me.

He reached up and lightly played with my nipples, flicking them gently back and forth with his fingers. I smiled nervously down at him as I pushed down, pushing the head of his cock into me.

My mouth dropped open in shock, and my eyes opened wide as I felt myself stretched like I'd never been stretched before. I let out a deep whimper and paused, just the top part of the head of his cock pushing me open. I trembled, staring down at him, breathing hard.

My mind raced. Was I actually going to be able to do this? Would I be able to even get him in? I decided that if I was going to do it, I was just going to have to do it all at once.

I suddenly drove myself down onto him, impaling myself on his massive cock. The feeling was completely overwhelming. The pain of being stretched like that was intense, but being so completely full of cock, combined with the pain, nearly pushed me over the edge just from mounting him. I shrieked involuntarily and heard him grunt in surprise as I sunk down onto him. My legs twitched and shook, and my body trembled. I panted for air, my eyes fluttering, on the edge of an orgasm from the intensity of it, just from getting him inside me.

I vaguely heard him mutter "Fuck you're tight", vaguely heard the doctor ask "Are you ok Tanya?" But then it hit me, my orgasm rolled over me, making my body shake controllably on top of him, impaled on the massive, glorious cock. I suddenly understood why some women adored big cocks. It filled me, truly filled me like I'd never been filled before. It was so deep and so thick that my stomach was bulging out above my belly button. I panted for air, my breathing ragged as I orgasmed on him without either of us even moving. The cock didn't just fill me, it possessed me, overwhelmed me.

As the orgasm slowly subsided, I looked down at him, finally able to focus again. I mumbled "S-sorry.. that, um, has never happened to me before.... Not like that..."

He smiled smugly up at me and asked cheekily "So you like my cock?"

I blushed deeply but nodded my head slightly yes.

He asked, "Need a minute before we proceed with the test?"

I shook my head slightly no and whispered, "I think I'm ready."

His powerful hands grasped my hips and pulled me up on his cock and then very slowly sunk me back down on it, starting to slowly fuck himself with me. It felt like my pussy was on fire as everything was stretched by his massive cock, yet it also turned me on like I'd never felt before. The massive cock seemed to fulfill a deep yearning that I didn't know I had. And to have him controlling me like that...

He started to thrust a little bit as he rhythmically lifted me and then pulled me back down onto his cock, matching his upward thrust. I panted, moaning, holding my own breasts.

We continued like that for a few minutes, him slowly but deeply fucking me. He glanced over at the pulse monitoring watch and said quietly "I'm only at 110. I'm going to need to fuck you harder. You ok with that?"

I groaned, whimpering, nodding my head yes.

He bent his legs, swung them off the bed, and lifted me, my pussy still impaled on his massive cock. He held me by the hips, looking into my eyes. I hung there, his cock buried deep inside me, impaling me. I felt like a doll, a toy, hanging there on his cock. He asked "Ready?"

I nodded, blinking. Then he lifted me almost off his cock. He paused briefly before pulling me down hard and driving his cock up hard at the same time, fucking me hard. I shrieked "uuungg... f-fuck!"

He started to fuck me hard now. I clung to him, my hands around his neck as he lifted me and drove me down onto his cock as his hips drove the cock into me. The feeling of being fucked like that was overwhelming. All that existed in my mind was the feeling of his all-powerful cock possessing me completely, filling me, stretching me. It felt like it was in my stomach.

I moaned incoherently, groaning, panting for air. He turned us around so that I was right in front of the doctor, back to her. She could see the massive cock stretching me, could see him pounding my tight pussy, taking me completely.

I clung to him, shaking uncontrollably, my arms around his neck, my legs around his waist. His strong arms held me tight, controlling me, driving me up and down on his cock. My pussy felt like it was on fire, a deep burning arousal overwhelmed me. I groaned incoherently, letting out an occasional yelp when he thrust in particularly hard and smashed his cock hard against my cervix.

He kept fucking me, his cock completely possessing me. My body bounced up and down on his cock, his hands holding me firmly by the hips, impaling me over and over on his glorious cock. My brain was a blur aside from an overwhelming need to for his cock, to feel it cum, to feel him reach completion inside me. I sputtered and moaned incoherently.

Then suddenly I came again. I came harder than I've ever cum before, letting out a loud shrieking cry. My legs spasmed, sticking straight out before him then snapping back, kicking him in the ass. My nails dug into his back, and my head lolled back, nearly limp as I came hard.

I heard him growl "fuuuucck....." as I came, my mind reeling, my vision blurry. Then he drove his cock ferociously into me, pulling me down even harder onto it, mounting me as deeply as I could be mounted. I flailed helplessly, still in the throes of an orgasm as I felt him explode, cumming hard. I felt a warmth deep in my core as he came. Not realizing the condom had failed, the feeling pushed me over the edge again, a second orgasm crashing over me before the first one had fully faded. I squirted, soaking him and his legs. I squealed, thrashing helplessly, gasping for air.

He held me there, helplessly impaled on his twitching cock as it pumped cum into my now unprotected pussy, both of us panting for air, shaking.

I finally managed to mutter "H-holy shit... that was....", my voice trailing off.

He moved over the bed and laid me down on my back, my body still shaking uncontrollably. He pulled out of me and looked down at the torn condom and said quietly "The condom failed. You're filled with cum."

I groaned softly "I thought it felt different..."

He asked softly "You ok?"

I smiled weakly up at him, staring at him, at his massive, half-hard cock with the torn condom still on it. "I've never cum so hard in my life."

He smiled a bit. "You're only the second person who has been able to complete a full reliability test with me. You were amazing."

I blushed, then giggled a bit. "Well, I guess you were ok too."

Just then the doctor cleared her throat. "Well, the two of you really stressed-tested that condom, and it doesn't look like it faired too well. This is valuable feedback for the manufacturer. I'll fill out the condom failure form. You don't need to fill out any evaluation forms. And you should both know that you're both up to date on your STI tests and that Tanya is on birth control. You can go get cleaned up now Dwayne. I need to talk with Tanya for a moment."

Dwayne smiled and stuck his hand out, shaking my hand as I lay there, still trembling, my pussy gaping open, his cum leaking out of it. "Good to work with you. Hopefully we'll be matched again soon." I gave him an amused smile at the formality of the handshake and nodded "I hope so." With that, he turned and walked out, cum-covered, semi-hard cock leading the way.

Dr. Morganson sat down on the bed next to me and smiled gently at me. "What did you think Tanya? Where you ok with that kind of test?"

I blushed, nodding my head yes. "Just don't do that to me every day! I'm going to be so sore walking today."

The doctor reached out and stroked my hair lightly, asking softly "May I examine your vagina to make sure there is no tearing given how big he is?"

I blinked in surprise "I, um, yes, I guess that's fine."

She moved between my legs and slowly slipped a finger into me. I noticed that she didn't put gloves on.

She slowly twisted her finger back and forth, pushing it in as far as she could, her other hand on my abdomen, pushing down from the outside. I bit my lip to try not to moan as she explored my extremely sensitive, recently fucked pussy.

She commented softly "You're much less tight then when I first examined you. He really gave you a workout."

I blushed a bit, nodding.

She continued to slowly explore me, occasionally pulling her finger out and looking at it. She smiled softly "I don't see any sign of tearing." I lay there, looking up at her, smiling softly. "Thank you doctor. I appreciate your concern."

She slipped her finger out of me and smiled a bit. Pulling an envelope out of her pocket she handed it to me. "Here you are. $200. You more than earned it. Willing to work with him again?"

I nodded. "Thank you doctor. And yes, I am willing to work with him."

She gave me a nod and a little bit of a smirk "I'm sure he'll be happy to hear that. Not many women can take him at all, and you just took all of him -- hard." With that she opened the door and stepped out, closing it behind her, leaving me there to clean up and get dressed.

I stood there for a moment looking at myself in the mirror. I was a complete mess. My hair was a mess. My breasts were pink. And my pussy was gaping open like I've never seen it before. I looked closer. The cum was still dripping out of me, dripping to the floor between my legs. I couldn't help but chuckle a bit. My friends would never believe I'd do something like this!

I cleaned up as best I could and then took an Uber back to my apartment for a proper shower.
