"Phew...what a day," Bonbon exhaled as she walked into her and Lyra's shared home, wiping some sweat off her head with a towel she had bought with her, "Lyra, I'm home!" she called out, only to get silence in response. "...Guess she's still out."

She then sat down on the couch, dropping her bag to the floor as she let out a bit of a sigh. She decided to go to the gym today, and invited Lyra to come along with her, but she refused because she had something planned for today. While she respected her wishes, Bonbon hoped Lyra would've come with her. In fact...Lyra had been pretty busy as of late. But with what exactly?

"Lyra..." Bonbon whispered before she gave a slight yawn. "...Maybe I'll take a quick nap before I head into the shower. I want to at least..." She paused as she yawned again.

However, unknown to the creamish-colored mare, Lyra was hiding out in the closet, a bit of a sly grin on her face as she forced back a chuckle. She had something special planned for Bonbon, and wanted to surprise her.

“...Lyra, I can hear your breathing.” Bonbon sighed.

“?!” Lyra tensed at that. “...Damn it.”

“Might as well come out…” Bonbon told her, her eyes still closed a bit as Lyra walked out of the closet, “You really upset me by not coming with me.”

“I was...busy,” Lyra explained.

“I thought we promised no more secrets?”

“We did. I just wanted this surprise to be special...more or less,” Lyra replied as she walked over to her friend/roommate.

“Lyra. At this point, nothing will surprise me,” Bonbon deadpanned. “I’ve been molested by a slime girl, I got eaten by a snake, a big-ass one, mind you, and I had to fake being a bride to an asshole indicator.”

“...I sometimes forget you’re a spy.” Lyra sighed a bit as she sat next to Bonbon. “You and that dictator didn’t…”

“Thankfully I kept it to blowjobs,” Bonbon replied. “I had to rescue Discord from this asshole caribou who planned to turn all the mares on the planet into sex slaves.”

“Woah, wait, what?!” Lyra gawked at that.

“Trust me. If I didn’t rescue Discord in time, your horn would’ve been chopped off and be used as some caribou’s sex toy,” Bonbon stated in a serious tone.

“...I….I….I see….” Lyra slowly nodded. “..well if I had to be a sex toy...I'd rather be yours~”

“Excuse me?” Bonbon blinked as Lyra leaned in close to her.

“You know at this point I love you...right, Bonbon~?” Lyra purred, whispering it into the creamish-colored mare’s ear. “Remember in the dream world we both wanted to be joined to the hip?”

“...That was still freaky, but yeah.” Bonbon slowly nodded. “I loved it.”

“Good~” Lyra smiled sensually, using her magic to lift Bonbon’s sports bra up, letting her luscious melons out into the open.

“Ahh! L...Lyra!” Bonbon exclaimed in a bit of surprise as she covered her chest. “What’re you…?”

“You’re a spy. You figure it out~”

“...You want to fuck...ok, I’ve had thousands of men and women before.”

“Of course…” Lyra nodded slowly as she took her own top off, letting her not as large, but supple breasts out into the open. “...Hold on...you’re not a mom, are you?”

“...Lyra, what did we agree on?”

“...Never ask about your age.”

“And not to keep secrets,” Bonbon added. “Now wanna see how to really have sex?” she asked, touching her before blinking when she reached her marehood, feeling something hard underneath her skirt.

“Surprise~”

“Is...is that a…” Bonbon blinked.

“A cock? Yes.”

“...How did you…?”

“Learned a futa spell from a spell book I bought at this adult shop in Canterlot,” Lyra explained as she stood up, taking off her skirt before moving onto her panties, letting her “rod” stand out in the open at full mast. “It’s temporary, though, and only lasts for the night.”

“I...I see…” Bonbon noted, a bit shocked at this, but also a little bit entranced as she looked at Lyra’s cock.

“Like what you see~?” Lyra teased.

Bonbon could only nod in response, the creamish-colored mare unintentionally crossing her legs as a bit of a wet spot started to form in her gym shorts.

“...Wanna do it with my clothes on?” Bonbon offered.

“But how will I…?” Lyra started before Bonbon tore a hole open in her gym shorts, exposing her butt and marehood. “Oh…”

“Also, you need to do it raw or not at all,” Bonbon added as she turned around and leaned forward on the couch. “Now...choose your hole so we can start~”

“...Hmm, why choose...” Lyra began before using a spell on herself, causing her temporary cock to split into two. “When I can take both~”

“...What kind of spellbook was that?” Bonbon whispered before Lyra gripped her waist, causing her to tense a bit as the unicorn mare rubbed her twin members against both of her lower holes. “Ahh~”

“Feels good, doesn’t it?” Lyra purred. “It’ll feel even better once they’re both inside~”

“Y...yeah~” Bonbon moaned a bit as Lyra continued to teasingly rub her cocks against her lover’s holes, Bonbon’s hips moving back to urge Lyra’s cocks inside her.

“Heh. Well...since you want it so bad, then…” Lyra began, positioning both her temporary members so they were aiming at Bonbon’s waiting holes. “Here it is~”

With that, Lyra slowly but forcefully thrust her rock hard “rods” into Bonbon’s pussy and flank-hole, causing Bonbon to cry out with pleasure as she was doubly filled. Lyra smirked a little as she started to thrust her cocks into Bonbon at an even pace, the creamish-colored mare moaning loudly while the mintish-green unicorn rode her like a dog, her large breasts swinging back and forth each time Lyra pulled in and out of her.

“Heh...better than a strap-on, huh~?” Lyra whispered into Bonbon’s ear, giving it a slight nibble as one of her hands reached for Bonbon’s luscious melons.

“Ahh~! I...I will admit...yes…” Bonbon panted, letting out another moan as Lyra gripped and began to squeeze her melon-sized breasts.

“Good. Then that’s two things I’ve managed to accomplish tonight.” Lyra grinned as she squeezed her friend/roommate’s breasts, “milking” them as she pinched and tugged a bit on the erect tan nipples. “Let’s see if we can go for three~”

“Heh…if you’re trying to milk me, g-go ahead...try it~” Bonbon challenged with a daring and lustful grin.

That was all the impetus Lyra needed to squeeze and pinch Bonbon’s nipples harder as she continued thrusting into her, building up speed and force as she moved. Bonbon panted and moaned out as Lyra continued to slam into her lower holes while squeezing her melon-sized breasts roughly. After a while, the two switched positions, and then Bonbon was bouncing up and down on Lyra’s cocks, her ample bosom bouncing as well in front of the mintish-green unicorn mare’s face while her shapely flank jiggled each time her hips collided with Lyra’s lap.

‘Ahh...mmmf~! Damn...didn’t realize I was this horny t-’ Bonbon mentally began before Lyra placed her mouth over one of her puffy, erect tan nipples, earning another moan from the creamish-colored earth pony mare before the unicorn mare’s hands found their way back to her supple rear, giving the cheeks a bit of a firm squeeze, “Ahh~! Damn...somepony’s getting frisky~”

“You bring out the animal in me,” Lyra purred teasingly, moving harder and faster inside Bonbon before softly biting Bonbon’s nipple, earning a loud moan of pleasure from the mare as she instantly climaxed, spraying one of Lyra’s cocks and the couch in her juices. ‘Oh ho~ somepony’s sensitive around the nipples~’ She didn’t have too long to savor this triumphant thought, as she felt Bonbon’s marehood squeezing the cock inside from her orgasm, pushing Lyra towards her own climax. After a few more hard thrusts, Lyra cried out as she came, too, her cocks releasing copious amounts of spunk inside both of Bonbon’s lower holes, some of it spurting out and landing on the couch and floor.

“Wow . . . and you have these all night?” Bonbon asked.

“Eh...eheh….yeah…” Lyra panted heavily. “Unfortunately...if I have both out at the same time after I cum...I get really exhausted, and the time they’re out is cut short.”

“...How short?” Bonbon asked before yelping a bit as the two cocks in her lower holes disappeared.

“Like that…” Lyra replied, giving a bit of a sheepish chuckle before she noticed the look Bonbon gave her. “....Uh….why’re you looking at me like that?”

“Don’t think you’re getting off this easily, Lyra Heartstrings.” Bonbon frowned as she got off of Lyra’s lap and reached down to under the couch, pulling out a box of sorts.

“....Uh….what’s in there?” Lyra slowly asked.

“You’ll see . . .” Bonbon replied in a whimsical singsong voice.

Lyra just blinked in confusion at that as Bonbon opened the box, the unicorn’s eyes widening a bit when she saw her pull out a strap-on. But...the reason she was shocked at the moment was the nearly foot-long stallion cock attached to it. “....Wh...where...did you get that?”

“You’re not the only one who went shopping.” Bonbon grinned, almost sadistically, as she donned the strap-on. “They called this model the BIG-mack~”

Lyra gulped audibly, though whether it was with trepidation or lustful anticipation, she couldn’t quite say.

“In fact...let’s lube this up a bit~” Bonbon stated as she climbed up onto the couch, making sure her “cock” was facing Lyra’s face. “Suck it~”

To Lyra’s own surprise, she obeyed without hesitation, taking Bonbon’s strap-on cock between her lips and sucking it into her mouth, both sets of lips drooling with desire from Bonbon’s newly domineering attitude. Bonbon didn’t waste anytime as she moved her hips back and forth slowly, causing her “cock” to slip in and out of Lyra’s mouth, placing a hand on the unicorn mare’s head to keep her steady. It would also do as excellent leverage when she really started going to town on her friend/roommate, the creamish-colored mare now practically deep-throating the unicorn mare.

‘Note to self: try to get my stamina up when I try that again on Bonbon,’ Lyra thought before Bonbon pulled out, her strap-on cock practically drenched in Lyra’s drool and spittle. “Gah...damn...you were getting really rough there, Bonbon.”

“Oh, you haven’t seen nothing yet, Lyra~” Bonbon grinned as she got down off the couch, but not before lifting Lyra up by her legs, her “member” practically brushing against Lyra’s pussylips. Lyra gave a small gulp as she looked down at the massive “cock” ready to penetrate her pussy, both in a bit of anticipation, and slight fear. “Don’t worry, I’ll be gentle . . . unless you don’t want me to be . . .”

“...G...go right ahead,” Lyra managed to get out. ‘I’m most likely gonna regret saying that, aren’t I?’

Bonbon smirked and thrust inside Lyra in one smooth, fluid, powerful motion, plunging deep into her marehood and spreading her lower lips wide around Bonbon’s strap-on phallus. Lyra let out a loud scream of shock and pleasure at the action as Bonbon began to roughly thrust her cock into her, the tip of it almost kissing her womb as her fairly large breasts bounced in front of Bonbon’s face. However, Bonbon had other ideas as with one swift motion, she turned Lyra around and held her legs up, making sure they were practically over her head as the creamish-colored mare continued to dominate her friend/roommate, Lyra screaming with ecstasy as Bonbon drove roughly and forcefully into her.

‘Ahn~~~! Damn...I knew I’d be regretting this..but Celestia-damn, does it feel so good~!’ Lyra mentally screamed out, her eyes nearly rolling into the back of her head as her tongue stuck out of her mouth.

“Told you I was gonna show you real sex~” Bonbon whispered into Lyra’s ear as she continued to ram her “member” up Lyra’s now-soaking-wet pussy. As if on cue, Bonbon began to get rougher and wilder in her thrusts, making sure to bury her strap-on cock in Lyra’s snatch, a bulge nearly evident around the mint-ish green unicorn mare’s stomach area.

“Best sex ever~” Lyra moaned, delirious from sheer lust and pleasure as Bonbon sped up her pace.

After a few more minutes of wild thrusting, Lyra was nearing her climax as her pussy clenched down onto Bonbon’s “cock” as she felt endless waves of pleasure shoot through her body. Bonbon drove even deeper and harder into Lyra’s marehood, feeling her own orgasm approaching as she continued. After a few more hard thrusts, both Lyra and Bonbon screamed out in pure lust and pleasure as they climaxed in unison, the former spraying out a lot of her fem-cum all over the floor and Bonbon’s “cock” while the latter creamed her strap-on, the “cock” attached to it releasing a sort of cum-like substance into the mintish-green unicorn mare.

“...Was that…?” Lyra began with a pant.

“No...it’s almost like it...to add a sense of pleasure, but none of... the high risk of impregnation…” Bonbon panted heavily as she plopped Lyra back down on the couch, “Also….we….are….even.”

“Y….yeah….” Lyra nodded in a tired manner. “. . . That was . . . incredible . . .”

“Best surprise ever...huh~?” Bonbon asked as she laid next to Lyra.

“Y...yeah…” Lyra nodded slowly, too tired to get back up. “...Want to….do it again….tomorrow night?”

“Depends...on how wild...you want it...to get…” Bonbon answered.

“Locker room...at the gym...when nopony else is looking?” Lyra suggested.

“Sounds like a plan,” Bonbon replied, smiling at the thought.

“Glad you like it.” Lyra smiled back.
