Horny

River stood at the kitchen counter, chopping up daisies for dinner. Sparks sat at the table, sorting through the mail. She sat slightly back, making room for her growing belly. She was 8 months pregnant now, and her belly had started to round out very nicely.

“There’s a letter from your brother.” Sparks held out the crumpled envelope. River stiffened but didn’t turn away from the daisies.

“Let me finish dinner first.”

Sparks finished sorting the junk mail out, set aside the bills, and got up to set the table. Her belly swung beneath her slightly as she set out plates, glasses of juice, and napkins. River placed daisy sandwiches on both plates and opened a bag of chips. They ate in silence for a while till River spoke, not lifting her eyes from her sandwich.

“What happened at my house after I ran out?”

Sparks looked up at her in surprise. “What?”

River swallowed thickly, still not looking up. “When we told them about the baby. After I ran out. Did you say something that would make my brother write to me?”

Sparks looked at the rumpled envelope with Leaning Oak’s name written in the corner and River’s smack dab in the middle.

“I told your siblings that we wanted them in our lives and that you love them. I told your parents that you just wanted to make them proud and that they should love you for who you are.”

River chuckled ruefully. “I’m surprised you didn’t scream at them like last time.”

“I figured you had already done enough screaming.” Sparks smiled. “Besides, they didn’t make me angry that night. They usually do but then they weren’t even able to put aside their bigotry for the sake of their grandfoal...that just made me sad.”

River smiled, finally looking over to the letter. “I’ll open it later” She stood and put the dishes in the sink, flicking her tail.

“I know you have had some...distractions that you could use some help with tonight.”

Sparks’ breath caught in her throat. “Oh? Is that so?”

River leaned over to pick a stray daisy petal off the floor, giving Sparks a long look at her ass. “Yes I think so.”

The pegasus felt her wings stiffen, and clamped them hard against her side. If she got a wing boner after so little teasing, River would never let her hear the end of it.

“And...what are you going to do?”

Running River walked slowly behind Sparks, trailing a hoof over the sensitive tips of her feathers. Sparks twitched and felt her stomach twist. The pregnancy had kicked her hormones into overdrive and she had spent the entire day with a light ache between her legs. Now it grew to a throbbing pulse, and she leaned subtly back into River’s touch.

The blue mare leaned in and ran her tongue over her girlfriend’s cheek, breathing soft warm breaths over the light fur there. Sparks closed her eyes and bit back a moan, crossing her legs in a vain attempt to get some kind of pressure.

“Wow…” River purred in her ear. “Pregnancy really has you all riled up doesn’t it?”

Sparks whined softly. “Baby...please…”

River only smiled and leaned in for a kiss. Sparks wrapped her forelegs around River’s neck and kissed her back hard. River’s hooves traveled down and rubbed circles on Sparks’ belly. She pulled back and bit down gently on Sparks’ neck, making her shiver.

“This belly of yours is really doing it for me.” River murmured.

“Oh yeah?” Sparks grinned mischievously. “You mean this belly?”

She stood up off her chair and walked in a slow circle around River, accentuating the swing of her belly and the curve of her hips. River growled and grabbed Sparks’ braid, causing her to gasp. Spark’s eyes went blank for a second as the tug on her hair sent lightning streaking down to her pussy.

River pulled her into another searing kiss as she caressed her hooves over Spark’s stomach, feeling the tight, hard curve of her skin over the foal. Pulling away, River led Sparks up the steps and to their room. As soon as they stepped inside, she shoved Sparks back onto the bed and climbed over her.

Sparks gasped as River kissed down her neck and chest, slowing at the curve of her belly, then continuing down. She smiled as she kissed the curve of her girlfriend’s thighs and felt her start to tremble. River dipped her head down and buried her muzzle between Sparks’ thighs.

“FUCK!!” Sparks hadn’t realized just how wet she was. River’s tongue swirled circles over her clit as the pegasus twitched and moaned.

“Fuck River fuck…” Sparks felt herself clench as River reached a hoof up and started stroking her pussy, all while never taking her tongue off her clit.

“Fuuuuuuuuckkk….” Sparks moaned deeply as River moved her tongue and sucked her clit into her lips instead.

“Fuck River I’m close…” Sparks felt the usual clenching in her stomach, which was so much more pleasurable now with her growing belly.

“Gosh baby already?” River purred, her hoof still torturing Sparks. “You must have been positively aching for me today…”

“Ooohhhh….” Sparks groaned and ground herself down onto River’s hood, searching desperately for more friction.

River pulled her hoof away and stood up off the bed. “Touch yourself.”

“What?” Sparks whimpered, sitting up and staring pleadingly at her girlfriend. “Why?”

The earth pony merely smiled. “Do it.”

Sparks collapsed back and reached down past her taut belly and circled the tip of her hoof over her clit. “Oh fuck…” she mumbled, her eyes closing. She fucked herself slowly while River rustled under the bed. When she finally returned, River was wearing a sky blue strap on, standing at the edge of the bed and offering her hoof to Sparks.

The pegasus’ eyes bugged out of her head as she mutely slid herself onto her hooves, completely transfixed by the sex toy swinging between River’s legs. The blue matched the hue of her coat almost perfectly. Sparks swallowed thickly.

“We...haven’t used that in a while…”

River merely smirked and walked forward, swinging the toy as she walked. She nuzzled herself under Sparks’ chin and maneuvered her to stand squarely in front of the bed. Sparks looked back over her shoulder as River ran her hooves along either side of her turgid belly. She let the soft touch continue back until she was gripping Sparks flanks.

“What do you want, baby?” the blue mare asked, a teasing tone to her voice.

Sparks planted her hooves and lifted her haunches into the air. “I want you to fuck me.”

River placed a kiss at the top of her tail as she rose up on her hind legs and mounted her girlfriend. She lined the strap on up with her vagina. Sparks inhaled sharply as the point of the toy pressed slowly into her. River took her time until the dildo was buried completely within her girlfriend. Then she shifted her hips, pulling the toy out and thrusting it back into Sparks’ soaking wet pussy. Sparks let out a loud, filthy moan and pressed her hooves harder against the floor.

“Oh my fuuuuuuucckkkkk...”

River caressed a hoof over the baby belly, loving the feeling of the tight skin and hard dome under her. Slipping her other foreleg behind the belly and between Sparks’ legs, she felt around softly before finding her prize. This time, when she thrust the strap on into Sparks, she also flicked her clit with her hoof.

“FUCK!!” Sparks threw her head back and shouted at the ceiling, her bliss falling from her lips in whimpered moans and gasping whines.

River continued flicking her clit, just like she knew Sparks liked, as she thrust her hips rhythmically against the pregnant mare’s eager vagina. She could feel herself getting embarrassingly wet and made a mental note to make Sparks’ mount her before the pregnancy was over.

When she leaned forward and ran her tongue over the sensitive feathers on Sparks’ wings, the pegasus almost fell over. Her forelegs started shaking as she hung her head low and moaned deeply.

“Ohhhhh Riveeerrrrrrr….”

River felt her girlfriend start to tremble as her clit pulsed to her heartbeat. “That’s it baby. Cum for me.”

Sparks was shaking, her belly swinging back and forth as River pounded her from behind. The attention to her clit and feathers were fogging her mind, and she suddenly felt a tightening somewhere by the point of her spine.

“Fuck I’m gonna cum….fuckfuckfuckfuckriverdontstopohmyfuuuuuuuuuckkk!!!!” Her string of pleas turned into a high pitched whine as River quickened her pace, thrusting her hips against Sparks and driving the toy into her over and over again.

Sparks screamed as her muscles rippled and clenched. “FUCK I’M CUMMING!!!!”

She threw her head back and moaned as her whole body pulsed and shook. River grabbed her mane in her teeth, using the hold to steady herself as she held Sparks’ belly with both hooves and slammed her hips back onto the dildo. Sparks screamed again, feeling her pussy clench around the toy. She collapsed forward, her forelegs finally giving out. Her rump stayed high in the air as River kissed her flanks and belly.

“By Starswirl’s beard River…” The brown pegasus took several deep breaths to slow her heart beat as her girlfriend undid the toy’s straps. When she was finally able to stand up, she turned and pulled River into a soft kiss. The mares stumbled over to the bed and laid down easily.

“I love you” Sparks mumbled in between short kisses.

“I love you too.” She felt River smile.

Sparks finally pulled away, resting their foreheads together. “So why do you like my belly so much?”

River blushed. “I like seeing our foal in you. I like seeing your belly grow each month and seeing how you just glow as you carry him or her.”

Sparks snuck a hoof down between her girlfriend’s legs. River gasped as her hoof brushed over her sensitive folds.

“Damn Baby. You are soaked.” River just moaned quietly.

Sparks’ eyes slid to the strap-on that had been forgotten on the floor. “You stay right here babygirl.”

River watched as Sparks rolled off the bed and buckled herself into the strap-on with great difficulty. She had to adjust the harness to fit over her new belly, but eventually she crawled back into the bed and laid on her back. The toy and her firm belly were on full display. River was captivated, running her eyes up and down her girlfriend’s frame.

“Now,” Sparks purred seductively. “With you all worked up already, I don’t suspect you’ll last long. But this way, at least you get to see us both.” She ran a hoof over her belly and looked pointedly at River.

The earth pony licked her lips and climbed on top of her girlfriend, sinking herself carefully onto the toy.

“Fuuuuuuckkkkk” she hissed as the dildo slid into her. Bracing her hooves on either side of Sparks, she lifted her haunches back up and slowly fucked herself on the strap on. Sparks reached forward and ran her hooves over the sensitive nipples on her lower belly. River moaned and opened her eyes, watching Sparks caress her.

Leaving one hoof to flick River’s nipples, Sparks returned the other to running slowly over her belly. “Look how big I’ve gotten.”

“Fuck.” River muttered, her belly already starting to clench. She really wasn’t going to last long if Sparks kept doing that. She moved her hooves to either side of the baby belly and moved her hips to slide the dildo along the front wall of her vagina.

“Ssshhhiiiiiittttt…” she hissed through clenched teeth as her pussy clenched.

Sparks grinned and sat up slightly, still fondling her own stomach. “Look at how our foal is growing inside of me. How the curves of my body have become this nice round belly.”

River growled and slowed her hips, trying to delay her orgasm. To her dismay, Sparks started thrusting her own hips, driving the toy into River at a torturously quick pace. The earth pony felt her pussy clench as she leaned down and took one of Sparks’ sensitive nippes in her mouth. Sparks moaned and the sound finally sent River over the edge.

“FUCK FUCK FUCK SPARKS OH MY SHIT!!!!” River hung her head and felt her hips twitch in time to Sparks’ thrusts. Her vagina pulsed and her body hummed with the rhythm of her orgasm. She moaned and whined as Sparks continued to rock her hips, drawing out every little drop of pleasure that she could.

When River was finally spent, she rolled off to the side and laid limp on the bed. Sparks slipped off the strap on and pushed it off the bed. River’s eyes were closed as her breathing slowly returned to normal. Sparks took one of her blue hooves and ran it along the soft fur on her belly.

“We’re going to be mothers.”

River pulled Sparks into a cuddle, wrapping her forelegs around her and protecting the baby belly between them.

“Damn right we are.”

Both mares, exhausted and limp, fell asleep safe and sound in the mutual embrace. Not even the light of dawn awoke them in the morning.
