My Curious Urologist, Part 8

"Time!" Jessie called out as she stood up and observed the streaks of cum I had just deposited in the trough. Gemma kept the huge dildo in my asshole.

"One minute, nine seconds," Pavel responded. and Jessie said, "OK, you need to measure their ejaculations. You can start with subject number two."

As Pavel made his way to the other trough, I felt Gemma pulling the huge dildo out of my butt and then she muttered softly, "oh, look at that. He's prolapsing!" Jessie moved behind me to see what Gemma was describing, and I heard them giggling as they looked at my loosened asshole and the fat rosebud I must be showing.

"Mmm, it's pushing way out, like it wants more. Look how it's flexing," Jessie said, and I felt some fingers exploring my puffy ass-lips. How far was my asshole opening up from the treatment I had just received?

"Ooh, it's so soft and slippery. It looks like a shiny red volcano with a little crease right here," Gemma said as she inserted a finger into the middle of my protruding ass-lips. The sliding sensation felt great on my relaxed asshole.

"Look how it's flexing. I think it wants more," Jessie encouraged, and I heard them giggling as Gemma added more fingers to her anal exploration. I was so loose, I easily accepted every finger with no problem.

"All that's left is ........" Jessie whispered, and I felt a slight pressure as Gemma added her thumb, and suddenly her entire hand was sliding into my rectum. The giant dildo had made my asshole so loose, Gemma was able to fist me! I had a girl's fist inside my anus!

"Oooh, look at that! You're in all the way. What's it feel like?" Jessie whispered again, and I wondered if they were supposed to be playing with my butt after we had finished cumming. I didn't care ....... her hand felt great inside. Her fingers wiggled gently as she explored the soft walls of my rectum.

"It's like I'm in a warm pussy. He's so soft ........... Let me twist it around ..........." Gemma said softly as she slid her hand around inside me, stroking her fingers against the tender walls of my rectum.

"He squirted 0.8 meters. I collected 75 cc of sperm. I need to ............ what are you guys doing? Are you playing with his butt, or are you just cleaning him up? I need to measure his sperm," Pavel said as he approached to do his job.

I felt Gemma's hand pop out of my asshole quickly, and both girls got back to business. "O.8 meters. Got it ............ 75 cc, that's about what I thought. Yes, see how far number one squirted," Jessie ordered as she picked up her clipboard. Pavel observed the trough before collecting my streaks of semen. 

"0.9 meters. It looks like 105 cc. That's quite a bit of sperm," Pavel observed, and Jessie chimed in, "oh, yes, he usually has a lot. This anal stimulation makes most men cum pretty good. Were you counting his spurts, Gemma?"

Gemma was now at the table with all the dildos, and she replied hesitantly, "I only saw about ten ..... was there more?"

"I was watching, and there were at least thirteen, if you count that last little one. That first one was a doozy," Jessie said as she put down her clipboard. 

"Gemma, you can unhook number two, and I'll take care of number one," Jessie ordered as she started getting me out of the harness. I was so exhausted, I thought I might slump to the floor when she got me out. Her strong grasp held me up as the harness fell from my naked body.

A similar reaction came from number two. Gemma wasn't as strong as Jessie, and I looked as I saw the young man slumping to the floor. "Oh god, I just can't stand up. I've never cum like that before!" he groaned as his arm waved weakly. Pavel came over to help pick him up, and the two of them escorted 'number two' out of the room.

"Well, I guess we're on our own. You really did well just now. You seem pretty tired ....... do you want an arm to hold onto?" Jessie asked as we slowly walked toward the door. I walked carefully so I wouldn't fall.

"I'll take anything you've got. I can't believe she had her hand all the way inside me! Does she do that to all .....?" I asked quietly as I leaned on Jessie's  arm.

"We don't usually do that, but your asshole took the biggest dildo, so Gemma's hand went in there easily. Your smooth little pucker sure turned into a big fat prolapse. Did you like being fisted? You sure had a big ejaculation from the dildo," Jessie commented as we walked down the hall. It sounded like she was admiring how wide my asshole could stretch.

"That was amazing. It helped a little that you grabbed my balls, but that full sensation was really making me cum. I've never felt that before," I said weakly as we reached my little dressing room. We went inside and Jessie helped me sit down.

"So, there's nothing more in here? You know I'd love another sample," she said slyly as she picked up my limp cock in my lap.

"Oh, you mean ............. I guess, if you ................" I hesitated, wondering how much she wanted to do. If she was offering her hot pussy, I could make an extra effort.

"It looked like you emptied yourself out, but I seem to remember that you had more last time. I'd love to feel your fat dick inside me again. It was really hot watching your asshole get stretched."

"You really liked playing with it? I'm sure you could still get a few fingers in there, since you had me so loose."

"Hmm, pop your legs up here. I'm sure you need a little clean-up ......... oooh, look at that thing. It's so small and cute again ........... not like that angry red rosebud that was popping out a few minutes ago. Mmm, my finger went in so easily .......... does that feel good? How about if I ............ ooooh, I'm in all the way. I can even feel your ............oh, there it is! You're starting to stretch out!."

"That does feel good ........ just keep your finger in there. What about ............ are you wearing panties this time?"

"Oh, you want in my pussy? Yes, I always wear panties, but they are pretty wet right now. Your performance in there was really hot, and your amazing asshole is really something. I'll bet Gemma's all hot and bothered, too. She really liked sticking her whole hand in your butt."

"Mmm, I can feel how wet you are. How about two fingers? Oh, you're so warm and soft. Can you climb up here on the table? I don't know if I have the strength to stand."

"Ahh, you want me to ride that nice pole? It looks pretty hard now. Let me get rid of this uniform and I'll ........"

"Oh, your boobs are so great! I remember you liked me chewing on your nipples ........... can I do that again?"

"You want permission to play with my tits? Just let me get up here, and I'll hang them right over your face while I ............. ohhh, your dick feels so good! Just lay there and I'll ride it."

"Mmmm, you've got such a great pussy! Just keep doing that and I'll have a big sample for you pretty soon. Can you lean down a little more ............... oh yeah, like that ............ lllmm, lllmmm, llllmmm ....."

"You really like my tits, don't you? Squeeze 'em all you want. My nipples are hard now if you want to bite them ........... oooooohhh!"

"Is that too much? I don't want to hurt you. How about this?"

"Aaahhhhh! Keep sucking and chewing! Oh, I love your big dick! Fuck me, baby ......... shove that thing deep inside! Harder ..... harder! Ooooooww!"

"Are you cumming? Ohh, my stomach is all wet! You really gushed ........ is there more?"

"Let me just ride you a little longer. Your big cock fills me up so nice! I'm so glad you came back for another study."

"I'm the one who's glad. I wanted inside your hot pussy again. Ohh, it feels so good ........"

"Are you gonna cum? I wanna taste your creamy load ........ I just have to lift up and ............ ooh, look at that thing. It looks ready to explode."

"I think I could last a little longer ........ sit back down and ........."

"No, we'd better finish up. I've already taken more time than usual to get you dressed. I'll just pop this thing in my mouth ........."

"Ooooh, that's so nice! Keep sucking ............. mmmm, you're getting me .............. let me get one of your fat boobs in my hand...... aaahhh, I'm almost ..............oohh, you're going in my asshole again! If you......Oooh ....... Oooohhh ............ Aaaaahhhhhh!!!"

"Mmmmlllmm ..... mmmllll ......suck, suck, suck .......... gulp ...... gulp ............ lllmmm ......slurp ............mmm, there's more! Mmmm, llllmmm ....... lllmmm ........ your cum tastes so good. I could feel your asshole squeezing my finger when you came. I think that's all of it. Just rest a minute while I clean you up, and we can get you dressed. There's quite a mess on your stomach."
