9:23pm

“Well I’m going to bed,” Spike says, yawning, and climbing off the beanbag that still has Libi on.

Libi smirks and shrinks her breasts back to her normal size, Twilight doesn’t notice this, actually she barely heard what Spike said, cause she is hanging her head down and trying her best to ignore Libi. She had been tortured by Libi’s breasts all day and the only time she got a break was when Spike went to make dinner, but even then she couldn’t take her mind off Libi’s… well you know... Something is seriously wrong with her…

Not to mention that for the final part of the day she had to deal with a painful boner, since her dick has decided to be active again. So in the end she hasn’t been able to do any work and all she has been able to think about is having sex with Libi, mostly with breasts involved. She hears the sound of Spike’s door closing, and after 10 minutes she decide she can’t wait any longer and just hopes that Spike fell asleep.

She stands up and approaches Libi, who is relaxing on the beanbag. Libi looks up at her and smiles.

“Need anything mistress?” Libi asks, trying to stand up, but she is suddenly pushed back down by Twilight. She raises an eyebrow at Twilight.

“Take them off!” Twilight growls, her eyes full of a hungry lust.

Libi doesn’t say anything and just clicks her fingers, magically undoing her armoured bra and panties. Twilight quickly throws away the bra and roughly grabs both of Libi’s breasts, making Libi moan happily.

“You’ve been wanting this all day, haven’t you?” Libi teases, her face flushing a dark shade of purple.

“Be quiet!” orders Twilight, who had enough of Libi’s smart mouth for one day. Twilight grabs and twists one of Libi’s nipples, causing the demon to squeal in pleasure. Libi has been making Twilight’s afternoon a living hell and now she wants payback! Twilight starts to aggressively fondles Libi’s breasts, squeezing, pulling and twisting them, treating them like playdough.

“Oh no! My breasts are getting raped by my mistress!” Libi moans happily, enjoying Twilight’s treatment, “She’s going to break then!”

“I said shut up!” Twilight grumbles, covering Libi’s mouth with her hand.

Libi moans into Twilight’s hands, but while Twilight roughly plays with her breasts she expertly moves her feet up to Twilight’s pants and begins to, unbutton and pulls down the zipper with her toes.

Looking at Twilight’s panties one wouldn’t think she had a massive penis at all, they are well fitting and there is no abnormal bulge. This is because Twilight has enchanted her panties to have a magical pocket in the front to store her massive dick, otherwise she could never of hidden it. Of course this means all her panties are held up by string that is tied up at both hips, so she can remove her panties in case she gets a boner, without having to break the panties.

Libi quickly undoes the knots and the panties fall away, except for the front which is most likely held up Twilight’s massive boner. Libi starts pulling the panties down her dick… Twilight groans, feeling soft fabric rub against her erect crotch, she looks down and finally notices that Libi has managed to depants her and is currently removing her panties.

“You cheeky little demon,” Twilight says, glaring at Libi, who smiles under Twilight’s hand.

Twilight removes her hands away from Libi’s mouth and knocks away her feet, removing the panties herself and revealing the fully erect dick. Twilight then straddles Libi lap and places her dick between Libi’s breasts.

“Make them bigger!” orders Twilight, glaring at Libi’s breasts.

“Yes, mistress,” Libi says, in a mock meek voice. Libi breasts begin to swell, until Twilight’s dick shaft disappear in the mountains of flesh, so now only Twilight’s flare and base is visible.

“Good, now you know what to do,” Twilight says, resting her hands on Libi’s knees. Indeed Libi does, but she wonders how Twilight does since she was only a virgin yesterday. Maybe she read it in a dirty book.

Libi grabs her now huge tits and starts to massage Twilight’s large cock with them, Twilight gasps as Libi’s soft flesh rubs against her cock. It feels wonderful, like her dick is stuck between two big marshmallows. Libi’s long tongue slips out and starts licking Twilight’s flare, making Twilight ache her back and moan at the sudden sensation. Twilight begins to subconsciously thrust her hips, making Libi yelp as the cock is suddenly thrust into her nose.

“Warn a girl next time!” Libi snaps, letting go of her breasts and grabbing Twilight’s tip, stopping her from thrusting.

“Sorry,” Twilight whimpers, wanting to continue thrusting, “It just feels all so good!”

“Well it is about to get better…” Libi says, before suddenly wrapping her lips around Twilight’s flare.

“Wait it is to....” Twilight says, trying to stop her, as all her pent up aggression disappears as soon as it came. But her warnings are stopped as Libi’s mouth opens unnaturally wide and letting Twilight’s flare slip in. “OH CELESTIA!!” Twilight moans, as her cock’s head gets wrapped up in Libi’s hot and wet mouth.

Libi removes her hands from Twilight’s dick and resumes her large breasts massage, while sucking noisily on Twilight dick tip. Twilight groans at the combined simulation and starts thrusting her hips again, plunging her dick deeper into Libi’s mouth. Libi isn’t surprised by this and instead starts bobbing her head in rhythm with Twilight’s thrust, letting Twilight reach deeper into her mouth.

“This feels good!!” Twilight groans, increasing her thrusting, trying to get deeper in Libi’s mouth, “But I want more!!!”

Twilight starts climbing over Libi, suddenly forcing more of her dick into Libi mouth and soon down her throat. Libi’s eyes widen as the dick is shoved down her throat, causing it to bulge at Twilight large girth, but she soon relaxes and lets Twilight continue to plunge the rest of her cock in. Soon all of Twilight’s cock is in and she is now basically laying on Libi’s face.

“This feels amazing, your throat is so tight! But I want more!!” Twilight moans happily, beggining to hump Libi’s face. Libi moans, the noise vibrating through Twilight dick. “Yes, moan more! It makes it feel better!!” Twilight says, happily, thrusting harder and making her balls slapping against Libi’s chin.

Libi moves a hand down to her own ignored sex, tending to it by plunging a finger deep into it, making her moan, while Twilight continues to roughly face fuck her. Libi is really enjoying this and continually moan’s, Twilight is too, Libi can see her face which is a state of total ecstasy, with her mouth set into a goofy grin, and her eyes all clouded over.

“I’m going to cum!!” Twilight moans, loudly.

Twilight grabs hold of Libi’s face and shoves her entire length in. Libi braces herself as Twilight cums, depositing her entire load right into Libi stomach, making it swell noticeably.

‘How can she cum so much after last night?’ Libi wonders, as her belly swells with Twilight’s baby batter. Soon it stops and Twilight lets go of Libi face.

“That felt wonderful…” Twilight says, a satisfied look on her face, “but now I feel kinda sleepy…”

Suddenly Twilight falls forward, the yesterday’s all night sex and today’s mad sex, finally taking its toll. Twilight falls into a deep sleep, her dick still lodged in Libi’s mouth and throat.

‘Great…’ Libi thinks, rolling her eyes, as Twilight hangs off her face, ‘Now how am I going to get her off me?’
