Back at the beach house, Spike was blindfolded and handcuffed to the bed he shares with Celestia and Luna. Laying on the bed with only a pillow to support his head, Spike could only imagine what could happen next. He did, however, feel Luna resting her body on his.

“Wow, Aunty Luna. I knew you were good at rope-binding, but I never knew you could tease this well. But why am I wrapped up like this?” Spike asked, looking around while still blind.

“Because me and your mommy have a special surprise for you~. It would be a waste if you could already see~.” Luna said before shoving her breasts into Spike’s face.

Spike could feel the softness surrounding his face as he caught Luna’s nipples in his mouth. Immediately, he started sucking on them without giving a second thought. It was clear to Spike that he had no idea what was in store for him. Whether it was good or bad, he had no idea what to expect. Regardless, he decided to live in the moment and suck on Luna’s breasts until the surprise would come to him. But at the same time this was happening to him, he felt petrified yet excited about what he was going to receive.

“Hello Spikey~.” Celestia said from across the room.

“You’re back here quicker than I anticipated~.” Luna said, turning to Celestia.

Looking from the bedroom, he saw her sister along with a naked Twilight right by her side, holding her left breast in her hand. Seeing this, Luna got off the bed and walked towards them.

“H-Hello? Mom? Auntie Luna?” Spike asked in a confused manner.

“Oh, what a lovely surprise~. I didn’t think you could convince her so easily.” Luna whispered in a teasing manner.

“I have my ways~.” Celestia whispered back before giving Luna a kiss.

Twilight felt a little perturbed by witnessing the Royal Sisters make out with each other, but her attention shifted towards Spike who was chained to the bed.

“So this is what you two normally do with Spike?” Twilight asked, looking at the bound dragon.

“It’s our way of destressing from our duties as princesses. Plus, it’s our way of growing closer as a family.” Celestia explained in a simple manner.

“Do you not wish to grow closer to Spike?” Luna asked in a concerned tone.

“I-It’s not that, but he’s your child. In some way, I’m also like a mother to him. I can’t just go over and-”

“Twilight, we made an agreement that there would be no complaining once we went inside the beach house.”

“Even so, Princess Celestia. Having sex with Spike goes far beyond consensual boundaries as far as interspecies.”

“Twilight, we implore you to give it a try. If you find this to your distaste, you may return to Canterlot. But trust me. You need this more than you realize.” Celestia said with sincerity in her voice.

“She is right, Twilight. You will thank us after your first experience with your Number One Assistant.” Luna confided, turning towards Spike.

“But-”

“The only but around here is what he often uses when he turns to buttsex with us. Yours, however, you will getting used to. But as for us~…” Celestia said, turning towards Luna in a loving manner.

“We have unfinished business to address~...” Luna said before embracing Celestia.

While Celestia and Luna proceeded to have their way with each other, Twilight was awestruck at Spike’s disposition. He was not only bound naked to the bed, but she couldn’t get enough of the big dragon cock she witnessed her entire life. She knew that she was heading to a road of no return, but Twilight knew deep within her soul that she was always stressed her whole life and it would never leave her unless she decided to succumb to her carnal desires as not just an alicorn princess, but also a friend to help deepen her relationship with Spike. Wasting no more time, Twilight moves herself closer to Spike’s penis and presses her face against the walls. It was warm yet cold, but at the same time was ready to burst all over.

“Here goes nothing…” Twilight whispered to herself.

She started by licking the sides first. The taste, in her opinion, was raw and salty all over. But somehow, she found it enticing on her tongue. Taking deep breaths, she placed his entire dick in her mouth and started blowing it. Moving her head up and down, she could feel the intense feelings crawl all the way to her brain. Grabbing his hips, she started sucking even further until he came into her mouth.

“Oh boy… you feel so good, Auntie Luna. Wouldn’t expect anything from the Moon Princess.” Spike said in a happy tone.

Giggling but still nervous, Twilight finally decided that enough was enough and decided to make the big step. Taking deeper breaths, she got on top of Spike in a cowgirl position and grabbed his hard cock. Having seen what has happened when losing her virginity in books, Twilight slowly inserted Spike’s penis into her pussy. This has caught the Royal Sisters’ attention while they were having sex with each other.

“Is she going to do it~?” Luna asked in an excited tone.

“She seems very determined~.” Celestia said, licking her lips in the process.

Slowly inserting the tip, Twilight could feel Spike’s rough penis enter her vagina. Bleeding slightly but unnerved while moving it inwards, it finally entered and Twilight lit up like a flash of lightning.

“Oh my~. This is the best sensation I’ve ever felt~!!!” Twilight bursted out in an erotic manner.

“Huh? Twilight?” Spike asked in a confused tone.

Having revealed herself, Twilight started gyrating her hips and moved faster on top of him. She moaned erotically the more she pumped him like a piston. But then she lowered herself down and kissed him passionately.

“Mmm~...” Twilight moaned while swinging her hips.

Feeling himself ready to climax, Spike held nothing back and got ready to fire his load into her. Twilight continued rutting Spike even further until he finally came into her.

“Ahn~!!!” Twilight shouted upon feeling his sperm fire into her.

Bearing witness to this, Celestia and Luna walked over and helped Twilight off her feet. Looking towards each other in a mischievous manner, Twilight decides to undo Spike’s blindfold. Upon opening his eyes, Spike was shocked to learn that it was Twilight who mounted him.

“T-Twilight! What a surprise.” Spike said in a shocked tone.

“What’s the matter, Mr. Dragon~?” Are you not happy to see me~?” Twilight said, placing her hooves near Spike’s mouth.

“N-No, but-”

“Honestly, my dear Spike~. I thought you would be happy to have Twilight join us~. After all, you do have a thing for us amazons~.” Celestia said, crossing her arms in a disappointed manner.

“I think he needs to learn a lesson in gratitude~. Do you agree, dear sister~?” Luna said before applying some lipstick.

“He certainly needs to be educated~.” Celestia concurred before putting her own lipstick.

“My No. 1 Assistant needs to know his place~.” Twilight before getting her lipstick on and tossing it aside.

“Uh-oh…” Spike said, looking at the three giant alicorns in sheer terror.

Wasting no time, the three lunged at Spike who had no countermeasures of his own.

“AAAAAAAAHHHHHHHHHH~!!!!!” Spike screamed at the top of his lungs.

The three alicorns continued to fuck Spike until early next morning.
