WARNING: Nasty details. BigMacintosh X TwilightSparkle X Applejack

...

"Take me now my slave," moaned Applejack as she paused her French kiss with her big brother, "I command that you take me now." She was still wearing the tight latex suit as she hugged her big brother about his neck, getting the cum he had just blown all over his upper body on it that he just ejaculated scant moments earlier. His cock was still semi-erect from the warm kiss he was getting, but neither it nor his balls were as harshly purple as they were before. In fact, they were almost back to their normal red color. The remains of the latex condom remained over part of his cock.

Big Macintosh seemed to be enjoying the hot kiss from his little sister well enough, but was a little confused by his little sister's desire for him to mount her. While she spied on his mare mounting activities in the past, he had always assumed she was just curious about sex and mating. He never really thought about the possibility that she secretly wanted him to mount her.

Twilight lay in the hay, panting and gasping after her near seeding by Big Macintosh. His cock was so strong that it defeated every precaution that they had taken. It burst a buckled strap on his shaft, broke the threads keeping the condom tied down, and then blow out the condom itself. Only by the swift action of Applejack was the seed spewed from his cock on his chest, neck and jowls rather than sitting in her womb. She wasn't entirely sure that even the spermicide in the condom was a guarantee against having Big Macintosh's colt.

Applejack climbed on her brother facing the opposite direction so her hot wet femslit was right over his mouth, and she then took the head of his cock into her mouth. She caressed his shaft with her hooves as she tickled the tip of his cock with her tongue. Big Macintosh moaned as she teased him, his erection regaining some of its firmness as his arousal level started rising again. He instinctively pressed his nose into her femslit, breathing deeply of her arousal scent, and then blowing his hot breath back out over her quivering wet nether lips.

Twilight moaned softly as she watched Applejack turning on Big Macintosh. She took her hoof and rubbed it over her hot soaking wet nether lips, feeling the tingling from her last orgasm. The one that nearly paralyzed her while his seed threatened to be pumped massively into her womb. But that just didn't seem so terribly important at the moment. She just felt warm and fuzzy as the heel of her hoof rubbed against her clit, making her more aroused and tingly once more.

Big Macintosh's large and wet tongue was now lapping freely at Applejack's femslit, licking at her clit at the end of the slurp each time, making her just a bit more slick, more aroused, and more tingly. She took more of his cock into her mouth as the erection slowly returned to its full strength as she gave it her oral manipulations. His balls seemed to swell again as they made a new reserve of cum for the next big blow-out.

"Do you have another condom?" asked Twilight, "Are you sure he won't blow out this one too?"

"Yes," moaned Applejack as she paused from sucking his cock, "I has another... and I has more of that wild-oat-icide too. When he cums the second time today, it won't be as powerful as the first time. I ain't worried about it."

"I wish I could be as sure as you," moaned Big Mac as he paused from his licking.

"You's talkin out of turn again, slave," answered Applejack, "must I punish you again?"

Big Macintosh fell quiet as he and Applejack went back to their 69 on each other. Once he was fully erect again, she pulled off the remains of the first condom and fished another out of the box. She took the second condom, partially unrolled it before loading it with spermicide, and them worked it around the condom lining as she slipped it over his quivering cock. She unrolled the condom, and once again left the last half foot or so of his cock shaft uncovered. Turning around, she looked at Twilight and asked, "Would y'all put his cock in my pussy for me?"

Twilight nodded as she came over and took his cock in her hoof.

Applejack presented her rump to his cock as Twilight lined up his renewed erection with her hot and quivering nether lips. She backed up slowly as his cock head parted her nether lips and pressed into her eager love hole. A moan escaped her lips as she felt him entering into her. "Oh yes," she said, "I've been waiting for this moment for so long now..."

Big Macintosh gave his own moan as he felt his cock going into his little sister's tight twat. Her vagina felt even tighter by the way the latex suit was squeezing her guts, including her vagina and nether lips. He never expected to see the day this would happen. He never expected how badly his little sister wanted him to make love to her. Inch by inch, he slowly penetrated her vagina with his huge cock. He was glad his sister was taking her time, as he knew his cock was very most likely the first cock that she had ever taken within her. In spite of that, he was starting to feel some weird sense of pride in the length of the shaft she was taking without complaint. He was nearly a foot into her before she even seemed to show any discomfort at all.

"Are you alright?" asked Twilight.

"I'm fine," moaned Applejack, "I can take more. Just let me take in a little more."

"Are you sure?"

"Ya, I's sure."

A few more inches, and Applejack was really clenching her teeth tightly.

"You're in pain, Applejack," said Twilight with concern, "please stop."

"No," moaned Applejack through her clenched teeth, "I can takes a little more!"

A few more inches, and then Applejack cried out. She had nearly taken the full length of the condom within her quivering vaginal canal.

"That's it!" cried Twilight, "No more!"

Applejack stopped pressing his cock into her, and then started backing off him. Twilight sighed her relief as she stopped pressuring herself. She backed out several inches before pressing his cock back into her. Once the cock was back in just as far, she reversed and let it partly slide back out. Big Macintosh moaned as she slid back and forth on his cock. Applejack moved back and forth more quickly over his cock, letting her arousal rise sharply as her love juices soaked her birth canal and made the rhythmic humping action on his cock go more smoothly. Twilight fondled his huge balls with one hoof and Applejack's throbbing clit with the other, as she was no longer needed to keep his shaft in line with Applejack's vagina. She simply watched as the juices were forced from Applejack's vagina to run down her inner thighs. Being where she was, she was first to notice a new knot of cum forming at the base of his cock just where it met his balls.

Applejack moaned as she was taken by her orgasm. She could feel the small flood of juices running out of her nether lips as she heard Twilight say, "Get off him, Applejack. He's gonna cum real soon."

"It's okay," moaned Applejack back, "let him cum in me. I jus know the condom will hold this time."

"Don't take that chance," said Twilight as she watched the know of cum work towards her nether lips, now stilled as Applejack was gripped in her orgasm. But Applejack made no motion to get off him. Once the knot was in her, it was too late to do anything.

Twilight's horn glowed as her magic began pushing Applejack off his cock and away from his jizz knot.

"No no no," moaned Applejack, "let me take it!"

"The knot is too big," cried Twilight, "and if it tears your vaginal muscles, it could take months or years for you to heal. I can't take the risk even if you want to."

"No please," begged Applejack as she moved further up his cock.

"I'm sorry," wept Twilight, "I can't risk your health like this. I can't risk my friend like this. I can't risk my love like this."

Applejack felt his cock popping out of her birth canal, and she would have collapsed into the hay if Twilight's spell wasn't still holding her up. She glanced back and watched his seed burst from his cock and flood the condom. The condom held as it flooded back more than a foot of its length.

The tears were flowing down Twilight's cheeks as she wept, "I'm so sorry, I'm so sorry."

Applejack wrapped her forelegs about Twilight's neck, cradling her head against her barrel as she cooed, "It's all right, it's all right. I can't be mad at you for thinking about me. I ain't angry, I ain't angry." Twilight was now bawling into Applejack's barrel as she was holding the violet unicorn tightly against her. Her tears were making them both wet.
