Tootsie galloped in with Bill, laughing and panting as they reached the living room together. All thoughts of winning the race were gone, because of the real reason they were here. "Hi Mrs. Nettle!"  Tootsie called out, along with Bill saying,

"Hi mom!"

"You two having fun?" the tall grey, green-haired mare said, turning from her reading to look their way.

"Yeah!" Bill said, the brown and red colt pausing to say, "We're gonna be up in my room, so no disturbing!"

With a small smile, his mom said, "Oh is that so? Well I'll be sure not to then. I'll see about having a snack for you two downstairs when you're done."

The blue haired, pink filly named Tootsie was amazed as they reached the second floor, and entered Bill's room. The floor was unusually clean for a colt's room, with a lot of space to move around. "I can't believe your mom is so cool!" Tootsie said excitedly, "My mom wouldn't let me do that!"

"Yeah, and we can do <i>whatever</i> we want in here," he said with a happy bounce. "Even touching, and... and <i>mating!"</i> he added in a conspiratorial whisper.

"Yeah, boys really... wanna put their <i>penis</i> in me?" Tootsie asked uneasily, turning in circles to look at her rear, "I didn't even know my place could do that."

"Well, I mean it's a really pretty place," Bill said shyly, "So you don't even have a... penis down there?"

"Nope, and I have a vagina I guess, but it's not really clear," Tootsie said uncertainly, turning her rear to him and lifting her tail, "So you think my... not penis place is pretty?"

"Yeah, it really is," he said looking in admiration, and perhaps something else.

Tootsie put a forehoof back there and tried messing with it. Her body was soft and pliable down there, and strangely tingly, but it definitely wasn't obvious. "I can't get it open," she said in slight frustration.

"Can I try touching it?" Bill asked. 

"S-sure, I guess," Tootsie said, looking back at him and planting her four hooves again. "I dunno why you like my butt so much, but... enjoy?"

"Okay, I'll just..." he said, ambling up to Tootsie with a curious sense of anticipation in her, "I've never even seen a girl up close like this," he said in awe.

"P-pretty good, huh?" she asked, trying to see under his legs, but it was too extreme an angle to see much. Then a hoof touched her labia and everything changed.

"Oh... wow that feels a <i>lot</i> different than when I do it myself," Tootsie said, staring forward in surprise.

"It's really soft..." Bill replied, "And you have a... a slit here, instead of balls. I guess this is your vagina?"

"Y-yeah," she said cautiously, "Your... balls that could put a foal in me."

"I won't do <i>that,"</i> he said, "I'm just playing around. Y-you're getting kind of... slimy."

"What?" she said faintly, blushing up a storm, "<i>Slimy?"</i>

"It's fine! You're just really... slippery?" Bill said, as his hoof sent deep tingles up into her.

...

With him mounted on her back, Tootsie just wanted to stand there and push her butt back. "I feel weird," she said breathlessly, "You're really gonna... put that big penis in me?"

"I-I just wanna try it," he said desperately, and slapped her belly with it. "I won't push hard, I just wanna see if it works." 

She whimpered as he slapped her belly again, then dragged his penis all along it, up to where her body was aching for it. She felt him nestle into her slit, then push his penis against her there, and she... opened.

"Oh... oh Celestia," Tootsie gasped, as Bill started to sink <i>into</i> her, "You're... you're going inside me!"

He hit home then, hunched against her, gasping, "You're really... hot in there!"

"I-I am?" she asked, beside herself with befuddlement. Bill shifted, and his <i>penis shifted inside her.</i>

"You're <i>slimy</i> my penis loves slimy I didn't even know," he told her. "I saw s-semen coming out."

"What?" she asked anxiously.

"It... I was touching it and it felt incredible and just started <i>squirting</i> out of my penis," Bill said hotly, "I couldn't stop doing it. If I did that inside you..."

"This is so weird..." she said dazedly, "Your penis I can... I feel like I'm wrapped all around it. I can feel where your... I'm thinking about your penis just... <i>squirting</i> out semen, and I can f-feel where you'd do it."

"Yeah but I can't do it unless I thrust," Bill declared, hunched over her with his penis flexing achingly within her. "So if I pull out it won't... squirt in you. But if I thrust..."

"Your fat penis is <i>smashed</i> up right against me in there," Tootsie said giddily, pushing her hips back into the colt's amazing, erect penis.

Then Bill pulled out, and pushed back in, then again and again. Tootsie started panting along with him, rocking back against his thrusting penis, as their eyes grew dull, and Tootsie only thought about the rising tingle in her vagina. Tootsie knew he was supposed to pull out, but he didn't. She didn't protest, she started <i>trying</i> to get a baby, thinking about that squirting semen, and his thick penis sliding all along her tingling passage, stretching her wide, and how he kept smashing up right where he was gonna squirt.

She wanted it more and more, the feeling building and building, until with a gasp, Bill shoved against her, sliding deep, and started twitching.

"Are you...?" she panted, looking back at him as semen spurted right into her birth canal. A troubled whine rose in her at the dreadful satisfaction of a colt's spurting semen flooding into her. "I-it feels weird," she said, "Putting a baby in me." Clenching around him, clenching, even as he spurted. "Oh, you won't <i>stop,"</i> she moaned as he spurted into her braced hips, and it started pouring out from their shared join and puddling on Bill's floor.

...

"Target didn't believe me," Bill said, standing with his friend before Tootsie, "So he's gonna prove it."

"Yeah, after Bill puts a baby in you, I'm gonna put it in just a little," Target said with a disapproving snort at Biil, "Because he's totally finishing inside you on purpose!"

"B-both of you?" Tootsie asked uncertainly.

"Well yeah, but not at the same time," Bill said, "You wanted me to keep going even after I put a baby in you."

"You didn't really," Tootsie said defensively, "It doesn't always put the baby in."

"Yeah, well I still say I couldn't stop," Bill replied equally defensively, "So after I put semen in, Target's going to mount you, and I bet he won't be able to stop until he puts a baby in you."

"As if!" Target retorted, sticking his tongue out at Bill.

"C'mon lemme," Bill said, nosing under Tootsie's tail, "Lemme under there so I can make my penis big again."

The colt started licking at Tootsie's vulva until she couldn't stop from lifting her tail aside. Tootsie looked apologetically at the other colt as she couldn't stop breathing harder or feeling the weird melting inside from that tingly feeling of a tongue sliding along her back there. "He has to do this to get big," Tootsie explained, blushing hard, "And it makes me get slimy too. I--I can't help it."

"Slimy?" Target said leaning back leerily.

"I can't help it!" Tootsie said with a stomp, "It just... starts feeling melty in there and..." she started rocking against Bill's snout, just as if his penis were inside her. "And I start wanting a penis." She bit her lip, adding, "I... I want a penis now. I'm getting all slimy <i>right now.</i> My... my vagina is getting ready for his penis to go inside."

Bill mounted her then, and Tootsie whined needily, as she felt his penis slapping against her, seeking her vulva. "He's... sliding it until he finds my... vagina he found it he's pushing it and I can't <i>stop</i> him."

As Bill's hips hit home, Tootsie moaned beside herself with need, "I feel it <i>sliding</i> into me. I'm <i>opening</i> oh oh..."

Bill just started thrusting then, and Tootsie couldn't think anymore with that sliding penis in her vagina blowing her mind. Target interrupted though, getting up to Tootsie's panting face and asking, "Are you really gonna let him put a <i>baby</i> into you?"

"I'm... gonna... it's gonna <i>squirt</i> in there," she purred, pushing back against the colt's thrusts, slit-eyed. "Pump his <i>semen...</i> into me and <i>change...</i> me..."

She stared forward, getting fucked so intensely she couldn't believe it, even though it already happened to her, and was happening to her. Thinking of the right words were hard. "I wanna," she moaned loudly, then more quietly moaned, "Big belly. Semen's gonna... my belly's gonna grow bigger and bigger. His penis... making me think about it. Wanna push a whole <i>baby...</i> outta my vagina... and be a mommy."

"I wanna be a daddy," Bill agreed hotly, "I wanna put all my semen in. Deep into <i>her.</i> I can't... stop..."

They just fucked silently then, gasping and thrusting, until Bill shoved into the panting, sweating filly, filling Tootsie up so incredibly with his big penis. "Target, he's doing it!" Tootsie whined, "He's--!" Then she grunted intensely with every burst of semen impregnating her deepest vagina. "It feels <i>good,"</i> Tootsie groaned in satisfaction, as Bill's seed started to drip out of her to the floor. "You're gonna do this to me too," she cooed at Target, grinding her hips up against Bill's.

Once Bill got off, Target was already erect, big time. Tootsie looked at it in interest, as Target said uneasily, "I don't think I could stop anymore. But I'm gonna do it anyway. I wanna feel what it feels like inside you, Tootsie!"

"Go ahead, feel what it's like then," she said presenting her messy rear to him invitingly. "Then you won't be able to stop until you're putting semen in me too."

Target advanced hesitantly, touching a hoof to her vulva. "It <i>is</i> slimy," he said distracted by the sight. "And <i>really</i> dripping."

"Bill's semen is... coming out of me," Tootsie admitted, flushed with desire and need, "Some stays in though. It's... swimming in me, trying to find my egg. You want your... semen trying to find my egg too, don't you?"

"Your egg?" Target asked tensely.

"I made an <i>egg</i> inside me," Tootsie moaned, "And when your semen finds it, it'll turn it into a foal. In my belly."

"S-so I..." Target mounted her clumsily, but instinctively.

"Push your penis against my belly," Tootsie instructed. When Target did so, she said, "Now <i>slide</i> it back to where it's slimiest. You can push against me, and it'll go <i>into</i> me."

He did so, and exclaimed in surprise as he started to sink into a lust addled Tootsie, "It's <i>hot</i> in there!"

"I'm hot inside," she said in delight, "It makes you put semen in, when I'm hot and squeezy and slimy. That's what Bill's penis loves."

"M-my penis loves it too," Target said, sliding all the way in, then pulling back a little, starting to thrust in her right away. "I-I'm...!" he said as his hips started to slide that penis in and out, in and out. "I'm putting a baby in you," he moaned, hugging her rear and thrusting for all he was worth.

"That's it..." Tootsie said through the haze of thrusting pleasure, "Keep doing that and... your penis will just start... squirting all on its own."

"Push deep into her when you can't thrust anymore," Bill offered, "That way your semen gets as deep in her vagina as it can get."

Target didn't answer, just humped Tootsie needily, and she didn't think she could answer either. She felt like Target's penis was rubbing Bill's semen into her, making her even more assuredly pregnant, and she wanted Target's semen to mix with it in her too. 

When Target heaved up into Tootsie and his penis started twitching, she said in hungry delight, "I'm gonna make your foal inside me!" Target's semen burst into her, and she added, "You're a <i>daddy</i> now. Put your seed... hard as you can. Find my egg." He held to her, and dedicatedly ejaculated into her, until every drop of semen had squirted out of him.

...

As they lay together afterward, Bill asked, "So was that okay?"

"...you got any more friends?" Tootsie asked hopefully.

...

The fifth colt began pumping his semen into Tootsie as her second orgasm ripped over her. Pleasure she never expected nor imagined, and it was happening again. She hugged the pole for dear life, helplessly clenching around this colt's penis while it spurted and spurted semen into her. She felt so warm and fuzzy, and happy, as the colt relaxed against her, and his semen tapered off.

"That was... the best thing I <i>ever</i> felt," he decared in shock.

"Your... penis is the best thing I ever felt," Tootsie panted, with a ghost of her clenches fluttering around it. "I love my vagina being full of your penis and semen, and your semen's in me now. S-seeking my egg, to turn it into <i>your</i> foal."

"I... I hope it's me," he said faintly but intensely, "I want you to have a big belly, with my.... my foal inside it."

"Then I'd push it out for you," Tootsie said indulgently, "For all of you," she said to the other colts, "Your baby I'd just... push it outta me back there. I wannit to <i>happen</i> to me."


The next time, they just started mating, just like that. Tootsie lifted her tail, he climbed on, and she gasped in need as he started thrusting into her. His penis slid in and out of her so much, until she was grunting, pushing back against him, feeling his spurts squirting into her so deeply.

blehhhhhh
