Sunset and Twilight

“I... I'm not sure about this.” stammered Twilight.

“If you want to be Princess of the Fall Formal, I suggest you get down on your knees and start sucking!” Rarity looked sternly at the new student. As per the rules of the initiation ceremony, Twilight was stripped of her clothes and stood in the center of the empty gymnasium before the two senior students.

Twilight gulped at the task ahead, but she knew she had no choice. She also couldn't stop staring at Rarity's rapidly stiffening cock. The fillies of this strange world were very unusual to say the least, and the fact that they had male sex organs was just one of many discrepancies that Twilight was going to have to deal with.

“Gosh, she's so... big!” thought Twilight. Rarity's cock was fully erect now and easily as large as Big Macintosh's.

Twilight felt two hands grasp her shoulders before pushing her to her knees. It was Dashie, or at least this world's version of her. Except for her boots, Dashie was naked and, like Rarity, her cock was swollen from excitement. Dashie motioned towards Rarity and gave her orders to Twilight, “Ok newbie, it's time for you to show us what you got!”

The new student with the oddly purple-toned skin opened her mouth to protest, but before she could utter any words, Rarity pushed her cock inside Twilight's mouth.

“Ummmpphhh!” gasped Twilight. Rarity's cock filled her mouth and her tongue instinctively began sliding under the cock, pressing and stroking the blood-engorged penis.

“I hope I'm doing this right!” Twilight thought to herself. She suddenly appreciated all those chats she had with Princess Cadence, those chats where her sister-in-law would go into detail about various little things which made Shining Armor happy.

Rarity closed her eyes, breathing rapidly. It was clear that the new girl was passing her first test. Just as she began to reach climax, Dashie interrupted.

“Geez! Are you done yet? What's taking so long? It should be my turn by now!” Dashie was hoping up and down impatiently, watching Twilight suck vigorously.

“Wait your turn, you little bitch!” Rarity was visibly agitated, her moment of bliss temporarily disrupted. “This girl is good, and I'm going to enjoy this as long as I can!”

Dashie fumed. Rarity usually didn't take long to come, but there was something unusual about this new student, and she couldn't put her finger on why. Suddenly, she remembered the special 'toy' in her backpack and she raced over to retrieve it.

She quickly returned with a long horse-like tail. The colours of the tail closely matched Twilight's own hair colour, even down to the violet streak. The base of the tail was firmly attached to a large tapered anal plug. It was obvious where this tail was going.

While Twilight continued sucking Rarity's cock, Dashie leaned down and whispered into her ear. “You think the first test is easy, huh? You're going to love part two. I'm going to rape your little ass!”

Dashie sneered at the new student who was crouched on the ground trying her best not to vomit. Moments earlier, Rarity's cock erupted, flooding her mouth without warning. The sensation of the warm semen sliding down her throat was almost too much for Twilight, but she knew she had to keep it down.

Grabbing Twilight roughly by her hair, Dashie pulled her head back with a jerk. “Bet you liked sucking Rarity's dick, huh, newb? Did her cum taste good, you little loser?” Dashie gripped Twilight's jaw and forced something round and hard against her mouth. It was a bright red ball gag.

Rarity's cock was hard again and she slowly stroked it, smiling as she watched Dashie tighten the straps of the gag around the girl's head. She complimented Twilight on passing the first trial of initiation. “I must admit you did a fine job, Twilight. For someone as inexperienced as you, I quite enjoyed your little performance.”

Dashie next fastened a leather belt around the girl's wrist, a sign to Twilight that her next ordeal would not be a pleasant one. Sitting down on the floor next to her, Dashie pulled Twilight onto her lap. Both girls were naked and Twilight could feel Dashie's warm skin against her bottom. Dashie reached down and guided her cock towards Twilight's anus.

Twilight's eyes widened in fear. “No! Don't put it in there! It's not meant for that!” Twilight's mouth was firmly gagged as her panicked thoughts fell on deaf ears. Dashie pushed the head of her cock against Twilight's hole, but the girl's sphincter muscles instinctively squeezed tightly, preventing any sort of entry. After several unsuccessful attempts, Dashie hissed at the frightened girl. “Stop resisting and just take it! If you want to join our club, you better learn to play! There's no way you're going to be princess of the Fall Formal without our help!”

There was no other option, and Twilight knew she had to yield. Without the help of these strange fillies, Twilight knew the chances of retrieving her stolen element of Harmony was nonexistent. She squeezed her eyes shut and somehow managed to relax her muscles. As Dashie's cock finally pushed through, the image of her mentor entered her mind. “Princess Celestia... I don't understand why this is happening to me. None of my books ever prepared me for anything like this, but I will not let you down!”

“Oh fuck! She's so tight!” squealed Dashie. She grabbed Twilight's thighs and forced the girl deeper. Suddenly Twilight's own cock began to shudder, and Dashie could feel the girl's sphincter muscles contract and squeeze against her penis. Twilight moaned loudly as her cock ejaculated, sending a huge stream of cum into the air.

“The girls are going to love this!” giggled Rarity. She carefully positioned her phone, ensuring that the scene was properly framed as she filmed Twilight and Dashie's show. “What do you think, Dashie? I think the new girl might just fit in!”

Dashie grunted as Twilight writhed and squirmed on top of her. “Oh she's fitting in alright! Uhhhnnn! She's such an awesome fit around my cock, I think I'm gonna make her my new cock cozy!”
