Challenge Accepted Part Two
A short unbirth story by: YummyTummy
Sydney tossed her shirt to the side and began to undo her pants; her fingers working quickly to undo the small button above her zipper.
“Are you absolutely sure about this? You could get stuck you know…” Olivia warned as she sat at the far end of the bed, watching her friend strip naked.
“Well, if I lose then I get to spend the night in your tummy, and it’s can’t be o bad in there right?” Sydney giggled as she kicked her pants down around her ankles before flinging them across the room.
“I guess…” Olivia replied, the uncertainty in her voice was noticeable now.
“Don’t tell me you’re backing out now. You made a big deal about me calling you a liar, and claimed that it was ‘So easy.’ Well now you’re being made to prove it and you want to quit?” Sydney said as she stamped her hands into her hips and mocked her friend.
“Hey screw you! I’m no liar!” Olivia blurted angrily as she crossed her arms.
“Then spread those legs.” Sydney smiled as she undid her bra, her tits pouncing from their confinement as she undid her laced undergarment.
“Fine, but don’t say I didn’t warn you.” Olivia warned as she spread her legs; her twat was already getting tight at the thought of something this big working its way inside.
“There!” Sydney smiled as she stood completely naked on the bed in front of her friend who was spreading her twat as wide as it would stretch.
“How should I start?” Sydney asked as she made her way over to Olivia.
“Just go feet first, that way you can help push yourself in.” Olivia explained.
“Doesn’t matter because there’s no way your fitting me in anyways.” Sydney reminded her with a smirk.
Placing her feet against Olivia’s pussy, Sydney shuddered.
“So wet and warm!” she exclaimed as she wiggled her toes inside.
Sydney’s smirk slowly disappeared as she realized that she was now ankle deep inside her friend’s pussy. Olivia had by now thrown her head back in pleasure as her friend slowly pushed inside her.
“Don’t wiggle around so much; if you make me come it’ll be way harder for me to fit you all the way in.” Olivia moaned as she squeezed her breasts in pleasure.
“Holy shit Olivia; my foot just touched that lotion bottle!” Sydney exclaimed as she slowly eased herself into Olivia’s twat until she was submerged up to her knees.
Olivia rubbed her tummy in pleasure as Sydney’s feet wiggled and kicked about, trying to force their way further and further inside of her. Olivia slowly began to ease herself forward, pushing Sydney further into her womb; her belly was now swelling to almost the size of a volleyball and it was growing every second.
“Slow down Olivia, I can’t—“ Sydney was cut off as Olivia surged forward; her lips enclosed around hers. Resisisting momentarily Sydney tried to push away from Olivia but found that she could no long move her arms; now that Olivia had slipped them into her twat.
Sydney moaned as her torso began to slip into Olivia’s pussy; her own vagina pressed against hers; and began to rub against the walls of her womb.

“You’re actually doing it!” Sydney exclaimed in disbelief as Olivia placed her hands on her shoulders and began to force her farther into her womb.
Olivia moaned in response but continued to push harder, enveloping Sydney’s torso completely and began sliding around her belly.
Sydney was riveted by the euphoric contractions of Olivia’s womb as she was sucked further inside of her.
Olivia leaned back; bringing Sydney up with her as she fell on her back. Sydney squirmed as she was rocked by a powerful orgasm; her moans of pleasure were soft and long as she fell deeper and deeper into Olivia’s pussy.
“I’m going to look so preggers!” Olivia moaned as she took her hands off of Sydney’s shoulders and rubbed her engorged belly with both hands as she began to thrust to the movements of Sydney as she wiggled around inside her.
“I…It feels so…good!” Sydney moaned as she was hit with yet another orgasm.
“Mhmm.” Olivia replied as she licked her lips hungrily; placing her hands back on Sydney’s shoulders she pushed harder as her friends shoulders began to slide inside her.
“How much more can you get in?” Sydney questioned as she helped to wiggle her shoulders deeper into her friend’s womb.
“Not…much more.” Olivia replied as he she strained to get Sydney’s shoulders inside of her.
“Looks like I might get the bed anyways.” Sydney laughed as she felt Olivia’s pussy swallow her shoulders and move up to her neck.
Olivia strained and moaned, gasping for a breath she lay back on her back and clutched her massive belly and clenched her teeth.
I’m not going to lose! She screamed to herself.
“So how do I—“ Sydney began but was cut off as Olivia’s hands clasped around her head muffling her voice.
Taking as deep of a breath as she dared Olivia gave one last push as she sucked Sydney’s head inside of her pussy with a tremendous effort that caused her to fall back on the bed almost instantly. Feeling her friend squirm and wiggle about in her tummy Olvia began to fondle herself euphorically.
“Mmmhm…keep struggling honey!” Olivia moaned as she clutched the bed sheets and flopped back and forth on her sides as Sydney came inside of her, kicking and tumbling around inside of her belly causing it to stretch and contort drastically.
Olivia screamed as a body tensing orgasm shook her body with such intensity that she soaked the bed sheets through to the mattress with her juices.
Sydney rolled around in the juiced that filled Olivia’s belly; her pussy contracted with multiple orgasms as she rubbed herself erotically. She moaned but no sound left her mouth as the warm insides of Olivia’s tummy muffled all of her noises and left her feeling overly tired.
Olivia suckled on her fingers; licking her cum off and rubbing it around between her legs and over her belly. Sydney had stopped moving as much and was now curled up in the bottom of her womb, sound asleep.
“I told you I could do it.” Olivia said drowsily as she patted her belly satisfactorily.
Olivia tuned on her back and caressed her breasts; her eyes slowly closed as she massaged her tits and belly and wondered how she would explain this to her boyfriend when he came to pick her up in the morning…
