A Midsummer Night's Cream

"Ugh! Damn this heat!" Cream Heart said as she fanned herself with her hoof. It was still only early spring, but there was already an unseasonal warmth in the air, and the mares of Equestria were feeling it especially so. She took a long sip from the mimosa in her hoof. "I don't know how you manage."

"You could always rent a stud," Stellar Flare suggested to her guest from the other side of her breakfast table. Cream Heart frowned. It wasn't that she was opposed to the idea...

"I wish I could. But with Button Mash home all day for the summer break, I'd never have the chance."

"I thought he'd be spending his every waking minute with that filly friend of his. Miss Rarity's younger sister there."

"Sweetie Belle. And no, she's not his filly friend. Just a regular friend, as I understand it."

"Aww. Well that must be frustrating for him. He seemed quite taken with her, as I recall."

"Mhmm. And now the one that has to deal with it is me!"

"Oh?" Stellar asked.

"Well sure! His bedsheets look like a modern art masterpiece after only a week. You've raised a colt on your own. You know how they get!"

"Mhmm. That I do," Stellar agreed. She tapped the rim of her empty glass with the tip of her hoof. On cue, her son, Sunburst walked into the breakfast nook with a pitcher.

"Refills?" he asked.

"Goodness, yes!" Stellar said, nudging her glass. "It's like the San Palomino Desert over here!" Stellar looked across the table at her guest as he filled her glass. "Within the safe, lay the key..."

"What?" Cream Heart asked.

"I'm saying that your problem and your solution are one and the same," Stellar clarified as Sunburst filled her glass. "The problem being that you are a mare in need of a stallion, and Button is in want of a mare to sate. The solution should be obvious."

"You don't mean to suggest that I should seduce my own son, do you!?" Cream Heart asked indignantly. She cut an uncomfortable glance at Sunburst. He looked away as he finished refilling his mother's glass before he turned to leave.

Stellar Flare raised her hoof slightly. "Stay." It was not the resolute imperative of a command, but the undertone of it was nonetheless stern. Sunburst obediently turned back to face the table and stood where he was with the pitcher. "This concerns you, after all. There was a time when you had an eye for that mare, Firelight's daughter, yes?"

"Starlight Glimmer," Sunburst answered.

"Ah yes. I recall you were quite heartbroken when you learned that she preferred the company of mares."

Sunburst pursed his lips at the bitter memory. "Yes."

"Her loss then," Stellar said without sympathy as she waved her hoof. "But one mare's loss is another's gain, no? Why don't you go ahead and have your breakfast?"

Sunburst looked at Cream Heart. "We have a guest."

Stellar looked at him, nonplussed. "I won't ask a second time, Sunburst."

"Yes, mother." He nodded and set down the pitcher on the table, then he crouched to go under the tablecloth. Stellar Flare leaned back in her seat and spread her legs. A moment later she was biting her lip. Cream Heart looked at her in shock. It took no stretch of imagination to guess what was happening under there. Even so, she leaned over and lifted her end of the table cloth. Sure enough, Sunburst had his face buried between his mother's thighs, licking away like a pony on the verge of dying of thirst.

Even with it happening right before her very eyes, Cream could scarcely believe what she was seeing. That two ponies would partake in such a lewd activity right in front of her at all, to say nothing of the incredibly taboo nature of it. Stellar's hoof gently ran through his mane and Cream sat back upright.

Stellar's pleasure was evident in her expression, but she yet kept some composure. "Shocked?"

Cream Heart absolutely was shocked. But her mind was swimming with questions. "When? How!?"

"As I said, when Starlight made things official with her marefriend..." Stellar said as she looked down to the stallion in her lap. "My Sunburst came back to the mare that had always been there for him. Isn't that right?" He made an affirmative, muffled noise in response. "As for how... it wasn't hard. As they say, there are two kinds of stallions; the ones who lust after their mothers..."

Sunburst briefly came up for air to answer, "... And the ones who lie about it."

"That's right," Stellar said, smiling at him as he went back to work. "Such a good boy. You know just how I like it." She stroked his mane with her hoof. "Such a good, good boy!" Her body stiffened and she shuddered in her seat. Her eyelids fluttered and then she refocused her attention on Cream Heart. "You will never find a stallion as loving, as eager to please, and as attentive as your own son," she said with a breathy voice.

Cream Heart winced. "I don't think I could bring myself to seduce my own son, though. It feels like such an abuse of our power dynamic as his parent."

"Then let him seduce you," Stellar said plainly. "All you have to do is give him the opportunity and be receptive! You could even bid Princess Luna to nudge him in your direction. She could give him very... specific types of dreams about you. That was how I got my Sunburst to come to terms with his infatuation. Isn't that right dear?"

"Mhmmf."

Cream Heart was still visibly squeamish at the idea. "That still feels too manipulative. If I were to do this with Button- IF I were to do it- it would have to be entirely his choice to initiate it!"

Stellar nodded. "Understandable." She gasped and put her hoof on Sunburst's forehead. "Alright! Alright, that's enough. I think you've earned your treat." She pushed out her seat and stood up to lean on her side of the table. Sunburst got out from under the tablecloth and walked around behind her with a plainly-visible erection bobbing under him. His mother flagged her tail and he mounted her. Stellar grunted as he pushed the full length of his dick inside her. She looked across the table at Cream. "You'll never know a perfect fit like your own son back inside you." Stellar glanced back at him over her shoulder. "Ms. Cream Heart needs a stallion, too. Why don't you see if she wants you to rut her? You could have a chance to rut some other mare!"

Sunburst let out a scared, pathetic whimper and buried his face in his mother's mane. "No. Please don't make me!"

"Shh, it's okay," Stellar assured him. "Keep going, Mommy loves you." She looked back at Cream. "You and I both know the sting of our stallions leaving us. But you'll never have one more dedicated and loyal than your own colt."

"I... I have a lot to think about," Cream said, finishing her drink quickly and getting up to leave. It did mean walking past them.

"Feel free to stay and watch as long as you like," Stellar offered as she passed by.

Cream Heart glanced back at them. From this angle she could clearly see the full length of of Sunburst's thick shaft sliding in and out of his mother's pussy. She would have been lying if she had said that she wasn't at least a little envious of her. She bit her lip watching Sunburst, who seemed not only compliant, but enthusiastic about the task of ball-slapping rutting. The dark patch of Stellar's damp fur spread down her inner thighs.

Cream Heart forced herself to look away, to will herself to leave and never look back. But instead, she turned on her heel and walked back to her seat in front of the other mare. "Fine. I'm in," she said. "But it needs to be his choice!"

"Don't worry..." Stellar said between panting. Sunburst grunted as he hilted a final time. Stellar's eyes crossed for a moment as she felt her son's penis flare before it started throbbing and pulsing, cumming deep inside her. Her eyes refocused on Cream Heart. "... I have a plan for that."
