Shining was sleeping soundly in his heavenly bed when he heard his bedroom door open. He groggily rose and checked the clock on his bedside table. 3:00. *Who could possibly be awake a this hour?*, he pondered. That's when he saw his sister trot into the room.
"I was having trouble getting to sleep, so I came here to see if you had any books I could read to get drowsy."
"Yea, sure. Go ahead."
As she walked over to the bookshelf, she noticed the bulge beneath his bedding. She blushed furiously. Shining followed her gaze until he noticed, making an 'o' shape with his muzzle.
"Um... yea..."
Shining began to think of Twilight in many indecent positions in front of him and blushed as well.
"I'm sorry for waking you up this early. Do you think I could... make it up to you?"
"I'm not sure what you mean."
"I don't know... You seem to have a big problem there... Maybe I could... suck it?"
"That would be gr-" "-But we can't! We're family!"
"But it would just be a one time thing, an apology. Unless... you wanted it to be more..."
Shining was conflicted. His little sister was offering herself to him right in front of his eyes. Noticing his hesitation, Twilight removed the blanket from him with a flick of her horn, revealing his slowly hardening shaft.
"Don't worry. Just relax and let my body do the talking. You'll enjoy this..."
And with that, Twilight pounced onto him, slowly rubbing him between her hooves, wanting to see him at full size. She didn't have to wait long. Shining turned out to be very well endowed indeed, boasting a 9 inch member with a girth to match. She started considering how she would approach this. Twilight had read that stallions enjoyed oral and 'deepthroating,' but she wasn't sure if she could handle that. Shaking her head and casting all thoughts aside, she plunged down onto the meat in front of her. Twilight managed to take about half on the first try, eliciting no shortage of grunts and spasms from the stallion under her. Feeling confident, she raised her muzzle until it was at the tip, before forcing herself down to the base. The sensation was strange. The position was uncomfortable, but not unpleasant. She attempted to breathe, inhaling the potent musk of his nether regions. Twilight comforted herself for a few seconds before raising herself up again. She soon set into a rhythm, roughly and quickly facefucking herself. Shining was in total bliss. He'd only had a few blowjobs before and he felt he would faint from the pleasure running through him. He wondered for a second where his sister had gotten this knowledge, but that was quickly cast aside with another expert ministration to his member. Time seemed to slow to a standstill as the events continued, an undefinable string of pleasured noises and muffled slaps echoing through the air. Eventually, Shining reached his limit.
"T-t-wi... I'm cumming!"
Her mind reeled at the words. She sped up as fast as she could, hoping to improve the experience for him. She moaned as she felt the first bursts of his seed enter her throat, eagerly swallowing. The act wasn't necessary, but she did it regardless. The world was nothing but the area where the two intertwined. Of course, the end had to arrive as his sex finally started to deflate. Twilight removed herself from his groin and quickly surrounded the member with her magic, instantly hardening it.
"Twi, what did you just do?"
"Well, I was hoping I could go further, if you're OK with it, of course."
Shining barely had time to think before he lustily whispered, "Yes..."
Twilight beamed as she heard this and quickly positioned her wetness above him.
"I hope you're ready..."
Twilight forced herself down onto him. She immediately placed a hoof in her mouth to muffle he her moans. If Shining had felt huge in her throat, he was a giant now. Twilight felt so full that she wasn't able to move. She couldn't think.
"Need some help?"
She quickly nodded and Shining began to thrust into her, loving the feel of her velvety walls surrounding him. Shining pulled her onto his chest, cuddling her as he continued his actions. He occasionally moved a hoof down to tweak her clit, causing her to clench around him. The warmth of Twilight, both external and internal, was intoxicating to Shining. He wondered how he had ever lived before today. Before this wonderful series of events came to pass. Shining lost track of time again as he fell into a rhythm with the motions. Twilight couldn't count how many times she came. It seemed that one orgasm followed another as she laid on his chest. Shining became discouraged after a few hours and stopped to ask Twilight.
"That... spell you used... Did it affect my stamina? I don't think I should've lasted this long."
"Oh, it'll only allow you to cum when I'm ready. Do you want to wrap this up?"
"Yea, I'm sorry."
"No.. No, it's fine. It's been long enough."
Twilight's horn lit again as she uncast the lock she had placed on him.
"Um, Twi. Do you want me to pull out?"
"Whatever you prefer."
Reassured, Shining continued his thrusts and when he reached his limit, he stayed inside her. Twilight shuddered as she felt the warm liquid enter her. She was so glad that Shining agreed to this, she couldn't imagine going another day without having experienced the sensations she was feeling now.
Shining, out of breath and completely contended, withdrew himself from her folds.
"I suppose I should sleep now?"
Twilight shook her head and pointed at the clock.
"It's 7, we should go downstairs and do stuff. Here, hold on a second."
She cast a spell that connected their horns for the briefest of moments before dissipating.
"There, now our minds have been restored to normal order. Who needs sleep when you've got this?"
Twilight pointed at her horn, smirking.
"I'm going to get ready, see ya in a bit!"
And with that, she was gone.
