The Cake Twins are home alone while their parents are out of town. Now teenagers, they are experiencing new things involving their bodies. At their age, hormones had started kicking in. Pumpkin Cake was going through her first heat, while Pound Cake was going through his first rut. Of course, most ponies in town already had a mate to help them with these urges, while the Cake Twins had nopony to help them with their overly controlling hormones.
In Pumpkin Cake's room, she was using her magic to move a dildo in and out of her cunt. Sadly, it didn't help her much. She screamed out in frustration, "Why can't I get off on one of these things!? I need a real cock or I'm going to go crazy!"
Meanwhile in Pound Cake's room, Pound Cake was clopping to PlayColt, but was also experiencing trouble getting off.
When he heard Pumpkin Cake scream, he sighed, "She's not the only one having trouble with the mating cycle. If only I had a marefriend…" He could smell his sister's scent from across the hallway and thought, "Her scent is so heavy, she must be really horny... Maybe we could help each- Wait, what am I thinking!? She's my sister! Then again..."
Back in Pumpkin Cake's room, she sighed, and said to herself, "I'm sure Pound Cake has a nice, big cock, but he'd never agree to do me." She went out of her room and saw Pound Cake in the hall and could see his cock, and she was right, it was huge for a colt his age. ‘How do you not have a marefriend with a cock like that?’ she thought to herself.
Pound Cake sighed, "Hey Pumpkin. Can I ask you something? Are you going just as crazy with the mating cycle as I am?"
Pumpkin Cake nodded, "Yeah, I've been trying to get off with toys, but none of them are working..."
Pound Cake gulped and said, "W-Well, maybe we could help each other out, if you want."
Pumpkin licked her lips and said, "Well... mom and dad are out of town for the weekend, so it's not like anyone will interrupt us. I guess if you want we could." she walked up to her brother and gave him a French kiss before walking into her room, swaying her flank, implying she wanted him to follow her.
Pound Cake followed his sister after the kiss and as he entered her room, she pushed him onto his back on her bed and moved to his cock to start licking it. "Damn sis, I didn't know you knew so much about this."
Pumpkin Cake was amazed at the size of her brother's cock. It was easily at least 6 inches long, and three inches thick. She jokingly replied, "I've read a few things and heard some things from my friends. But that’s nothing in comparison to a package like this; how do you not have a marefriend with a cock like this? I'm sure there's a lot of mares who are missing out on this." She continued to lick she continued to lick her brother's cock, swirling her tongue around the tip of it as she stroked the base with her hoof.
Overcome by her ministrations, Pound warned her of the torrent to come. “S-sis, I think I’m about to cum!”
With a coy smile, she simply replied “If you think you’re going to cum now, just wait until you feel this." She shoved as much of his cock down her throat as she could, pushing as many inches down her esophagus without choking before pulling back up, massaging his length in a seemingly endless battle between the saliva coating his length and the air greeting him with each bob. Pound finished up with a kiss to his flared head before it couldn’t take any more pleasure, releasing his virgin seed across her face for the first time, coating her face and fur with his newfound desire for a mate. Surprised, but no less daunted, she gathered the seed from her face and licked it off her hoof, gauging his reactions as his cock hardened to its former glory, while she sat back in satisfaction at the tantalizing taste of her brother’s semen.
"D-Damn sis, that was great. Want me to return the favor?" He asked as he turned her over and began licking at her folds, pleasantly surprised at the flavor of her essence. He teased them with his tongue for a short while before he entered her core, eating out her pussy for all it was worth.
As Pumpkin Cake swallowed her brother's cum, she said, "Mmm, your cum tastes great, it's thick and salty, just like mom's Salty Caramel Pretzel cake." Afterwards, she laid down on the bed, spreading her legs apart, "In answer to your question, yes, I'd like you to return the favor."
Pound Cake positioned himself to start licking his sister's cunt. It was dripping wet, and as he licked, he also lapped up some of her pussy juices. He swirled her tongue around her clit, as well as sucking and nibbling it. As he did, he plunged his tongue in and out of her pussy. "You taste amazing sis. Are you ready for the main event?"
As her brother licked her cunt, Pumpkin Cake moaned. When he stopped and asked if she was ready for the main event, she smiled and turned herself over, putting her flank in the air, "Mount me like a real stallion."
Pound Cake smiled back before mounting his sister and plunged his dick into her soaking wet pussy, "Wow, you're so wet I'm not having any problems moving in and out." As he plunged in and out of her, he could feel her cunt tightening and loosening around his cock. "Damn, this is the best!"
As Pumpkin Cake panted, she cried out, "Oh fuck yes! Fuck me like the slut I am bro! Make me your bitch!" she could feel her brother's cock pounding into her pussy, and she was getting close. She grinned to herself and asked Pound Cake, "H-Hey bro, want to try something new? I've got an idea."
Pound Cake raised an eyebrow, "Um... sure, what do you have in mind?"
"Just trust me." Pumpkin Cake used her magic to move a vibrating butt plug and shoved it up her brother's ass. When she turned on the vibrator, she asked, "How's it feel?"
Pound Cake yelped as the butt plug entered his ass, but as the vibrator went on, he moaned, "I never knew having something up my ass would feel this good. It's making me even hornier." As he continued to plunge his dick in and out of his sister's cunt, the vibrator up his ass made him even closer to his climax. "I can't hold back anymore, that vibrator's making me cum early!" before blowing his load into his sister's pussy.
Pumpkin Cake cried out in ecstasy, "Oh yes! Fill me up!"
As Pound Cake pulled out, his sister's pussy was filled with so much cum it was dripping out. He panted in exhaustion, but his cock was still hard, and the vibrator was still making him horny.
Pumpkin Cake looked at her brother and grinned, "So, how was the butt plug? Would you be willing to try some more kinks?"
As Pound Cake finally caught his breath, he said, "Maybe, what did you have in mind? Also, can you get this butt plug out of me, it's making me go crazy."
Pumpkin Cake giggled as she magically pulled the butt plug out of her brother's ass, then said, "Well, what about some bondage? I've seen you watching those internet videos about it, so you know more about it than I do."
Pound Cake blushed, "Y-You were spying on me when I watched those!? Under normal circumstances I'd be mad, but bondage does sound like fun. But just for the record, it can hurt a bit, so we should probably think of a safety word if it gets too intense."
Pumpkin Pie thought for a moment and said, "How about 'red velvet?' If I say red velvet, that's when we stop.”
Pound Cake nodded and said, "I'll go get my equipment. I ordered some stuff from that bondage website, and I've been hiding it from mom and dad." As he walked to his room, his sister followed him. When he opened his closet, there was rope, spanking equipment, gags, and a lot of other BDSM stuff.
Pumpkin Cake's eyes widened at the sight of her brother's BDSM collection, "Wow... you might have a bit of a problem. But I'm still willing to do this for now."
