In the castle's library, Twilight Sparkle walked slowly around the central table with a long parchment and a quill floating in her magic, checking over what she'd written once again. Starlight Glimmer trotted along beside her, smiling broadly with a light spring in her step.
“Alright, let's go over the ground rules one last time so we're both absolutely clear,” Twilight said as she finally came to a stop. “Ready, Starlight?”
Starlight took position beside her, nodding once. “Absolutely. Triple-checking the rules before we begin. Let's do this!”
Twilight chuckled at her friend's eager response. “You've been very patient, Starlight. Thank you for bearing with me. I feel a lot better about doing this now that we've worked out these rules.” Lifting the parchment again, she began to read.
“One. This session will last no longer than four hours. Two. At my discretion I may end the session early if either of us appear distressed or any emergency should arise. Three. The spells will include an emergency escape trigger that you can activate by thinking of ending the spells while repeating the safeword 'caravan' five times in your mind. Four. You may trigger the safeword at any time without penalty or repercussion.”
Twilight looked up from the parchment. “That was the right word for it, wasn't it, Starlight? A 'safeword'? That's a very clever turn of phrase for what it does. I'm impressed.”
Starlight nodded. “Yep, that's the right word, but, um, I didn't make that one up. There's a lot of ponies who play in a dangerous way, and it's a common term they use.”
Twilight's brow raised. “And you know that, how?”
She laughed. “I told you I decided a long time ago it was okay to get my needs met. I spent some time exploring what those needs were.”
Twilight blushed a little, letting her imagination wander. “Oh, of course. Let's finish up.” She buried her face in the parchment again.
“Five. All activities during the session are done with the full consent of both of us. If there is any doubt to consent the activity will not be done until consent is established. Six. No other creature is to ever be told what happened in this session.” She looked up again. “I'm still not certain it's a good idea not to catalog exactly what we are consenting to.”
“As I said earlier, I'm giving consent to anything you might request of me, Twilight. I trust you completely. If anything unexpected comes up, we have the safeword to stop things right away.” She grinned at the thought. “Besides, we'd be here all night if we tried to document everything.”
Twilight sighed, nodding. “I suppose you're right. I might just be a little nervous, and detailed lists always calm me down.”
Starlight giggled. “I noticed, Twilight.”
Twilight rolled her eyes, rolling up the parchment and setting it and the quill on the table. “Alright, alright, let's move on, then. We know the spells we'll be using for this session and how we'll combine them.”
“I had a thought on that, actually,” Starlight interrupted, floating the spellbooks over from their places on the shelves. The books opened to the required pages, hovering before them both. “I think if we add a little more Persuadere here... and tweak the Cogeria by removing this bit... and supplementing it with more of this part of Fiducia Compelus, that should eliminate most of the headache after the spells end, and clear up the memory issues I experienced before. That way I'll have a complete recollection of what happened while I'm under your control.”
Twilight smiled as Starlight explained the changes, picturing the alteration of the spells and how they would do exactly what her student intended. “I'm still deeply impressed with your magic skills, Starlight. You're right, that should lessen the aftereffects of the spells on you. I'll make those changes when I cast them.”
It was Starlight's turn to blush under the praise. “Thanks, Twilight.”
They stepped into an open part of the room, close together and facing each other. Twilight cleared her throat. “I, Twilight Sparkle, consent to place Starlight Glimmer under my magical control,” she intoned formally, looking Starlight in the eyes.
Starlight smiled and raised her chin, putting on her own formal voice. “I, Starlight Glimmer, consent to being placed under Twilight Sparkle's magical control and to obey her every command while I am.” She chuckled. “I still don't think we need to be this formal about it, Twilight, but if it makes you more comfortable, that's fine.”
Twilight smiled. “Thank you. So, are you ready for the spells?”
“I did have one more thing I wanted to cover in detail,” Starlight said quickly.
“Alright, Starlight. What's on your mind?”
She stepped a little closer. “When we were talking you mentioned that when it comes to sex you've never done anything with anypony else, and that you had no... empirical data about if mares do anything for you, right?”
Twilight's eyes grew wide and her cheeks grew red as Starlight spoke. “Ahh, yes, I suppose,” she stammered.
“I've already consented to do anything you command during the session,” Starlight continued before her mentor could object. “Given the circumstances, I want it to be clear that consent includes any... data gathering you may want to do on this topic. In short, if you want to find out what being with a mare is like, I'm yours to command.”
Twilight stared, her jaw hanging open. “I... I'm just not sure that would be, ah, appropriate. I mean, you'll be under a spell and-”
Starlight reached up and placed a hoof over Twilight's mouth, silencing her. She looked into her eyes, smiling warmly. “I consent to anything you order me to do, Twilight. I'm not asking you to make that command, I'm just letting you understand the option exists, and I'm perfectly okay with it. The choice is entirely yours.” She lowered her hoof. “Are you ready for us to start, or do you want a minute?”
It took a moment for Twilight to compose her thoughts, standing there staring at her friend. “I, um, I appreciate that clarification, Starlight,” she managed to say. One steadying breath later, she added, “I'm mostly worried it will bring up your feelings about what happened with Silver Spark. I don't want to ruin this for you.”
Starlight shook her head, a gentle smile still on her lips. “This moment has nothing in common with that time, and it never could. I trust you, as a friend and a mentor, and as your friend I want to help you out in a way that only I can. We're both exploring new ground with this session, and I don't want fear to hold that exploration back.”
Twilight watched Starlight's body language as she spoke. Steady and certain, but still eager to move forward, she could almost feel Starlight's excitement. “I'll admit, I am curious how this will all play out. Alright, Starlight, I'm ready to move forward on your word. I won't promise I'll ask anything intimate of you, but I'll consider the option open, as you wish.”
Starlight's smile grew into a wide grin and she stepped out into the open space in front of Twilight. “I'm ready. Go for it.”
As before, Twilight's magic swirled together into a large orb over her raised hoof while she wove the spells together. With a gesture she sent the orb flying into Starlight's forehead light filling the room. She didn't hesitate this time, setting her eyes aglow as she intoned the trigger phrase. “Starlight Glimmer! Hear my voice and listen!” Another flash of light flooded the room, and Starlight stood still, smiling, her eyes wide and blank.
Twilight took a moment to walk around her student, taking more care to study her features and her stance from different angles. There was no doubt, even seconds into the spell she was already showing signs of arousal. Returning to the front of her, Twilight ordered, “Starlight, tell me how you are feeling.”
“I am feeling horny and very happy, Twilight Sparkle,” she responded without inflection.
Twilight smiled at that, nodding. “I'm glad to hear it. Once again my spellbooks are not on the shelves. Please return these three spellbooks to the correct locations on the shelves, by hoof.” She floated the books to her friend.
“Yes, Twilight Sparkle. At once, Twilight Sparkle.” Starlight took the books eagerly, trotting to the bookshelves with her tail held high.
I guess her presenting will be a constant during the session, considering how the spell affects her. She watched Starlight quickly shelving the books, efficiently finding each correct spot. I could order her to lower her tail, but I guess it doesn't hurt anypony.
Moments later Starlight stopped, turning to face Twilight. The books were back in place. “Very good,” Twilight praised, walking over to her. “Now I seem to remember we left a mess on the rear balcony. Go to the balcony and clean up after our dinner. Place any leftovers in the kitchen. Place any wrappers or other trash in the garbage can. Clean off the table with a wet tea towel, then dry it with a dry tea towel. Begin.”
“At once, Twilight Sparkle.” Starlight turned and trotted out of the room, heading for the stairs to the rear balcony.
Twilight followed at a more leisurely pace, silently reviewing the tasks she'd planned for her student to complete during the session. Watching Starlight eagerly climbing the stairs, another thought kept intruding on her carefully-laid plans. Even if she says she's okay with it, I shouldn't really ask her to do anything like that, should I?
She watched as the remains of their dinner was cleared away, exactly as instructed. Much sooner than she'd anticipated the task was done and Starlight stood there, waiting for new orders. Her arousal was much more evident now, with the base of her tail glistening in the lamplight.
“Starlight, tell me how you are feeling,” Twilight commanded again, looking into her friend's eyes. She's going to make fun of how much I ask her that when she wakes up.
“I feel very horny and happy, Twilight Sparkle.”
“Very good, Starlight. Follow me. I have several more tasks planned for you.” She turned and trotted back into the castle, Starlight following close behind her and matching her pace. “Time for you to get us some tea,” Twilight said confidently, leading her charge to the kitchen.
Over the next two hours Twilight walked Starlight around the castle, commanding her to perform menial tasks from cleaning to cooking to serving her tea and fresh-baked scones. Starlight never faltered, performing each task exactly as commanded with a smile on her face.
“I feel very horny and happy, Twilight Sparkle,” Starlight replied to the latest check-in by Twilight. A quick glance between her flanks confirmed every word.
She really is enjoying every minute of this. Twilight led her friend through the castle halls. She reviewed the mental checklist of activities she'd planned, finding it completed with nearly half the time scheduled still remaining. What can I have her do now?
She stopped and looked back at Starlight, searching her blank smile for some inspiration. She circled around her again, chewing on her lip. I really shouldn't. I know she said she's OK with it. Twilight took a deep breath to steady herself, catching the rich scent of her friend's arousal when she did. She's under a spell. I should be looking out for her best interests.
She looked Starlight in the eyes once more, trying to glean some further clue. She was so focused she didn't even notice her own legs pressing together against the sensations growing between them. I really need to relax.
Her smile returned and she asked, “Starlight, do you know how to give a massage?”
“Yes, Twilight Sparkle.”
“Good! Come with me.” Twilight led her quickly now up the stairs and to her bedroom. “Bring the window seat out to the middle of the room with your magic, Starlight.”
“At once, Twilight Sparkle.” Starlight's horn glowed bright and the low, long, padded stool by the window floated out to the room's center. While low, it was the perfect length for Twilight to lay over it while allowing access all around to Starlight.
Twilight stepped into her private bathroom, opening the sole cabinet with her own magic and pulling out several bottles. “Aha!” she cried on finding the right one, floating the rest back into the cabinet. “I wasn't sure I'd ever make use of this scented oil Rarity gave me.” She trotted back into the bedroom with the bottle floating behind in her magic along with a couple folded towels. Smiling at the position of the bench, she spread a towel over the cushions and set the oil and other towel to one side.
“Excellent work, Starlight. Now, I'm going to lie on the seat and I want you to give me a thoroughly relaxing massage.” She didn't wait for the reply, straddling the bench and settling down onto her belly.
“Of course, Twilight Sparkle. A thorough and relaxing massage. You will love it.” Starlight floated the bottle with her magic, warming the oil before pouring a little on her hooves. Immediately she set to work, rubbing the warm, fragrant oil into the muscles of Twilight's neck. The scent of roses filled the room.
Twilight sighed and immediately started to relax, the slow and sensual massage occupying her senses and loosening her muscles. I should have thought of this sooner. Now we can fill the time left without having to make a decision. She closed her eyes, nestling onto the towel and letting her thoughts drift.
Starlight proved a very attentive masseuse, slowly massaging down over Twilight's back. She took extra time to gently work the wing muscles before proceeding along her flanks, spending time to work each leg individually down to the hoof. Working the base of the tail, she moved out to the rest of Twilight's rump, persuading the thick muscles to relax again.
Twilight moaned softly with the wonderful sensations, her body limp under the expert attentions of her student. She didn't tell me she was this good. She nearly drifted off to sleep, feeling Starlight's slick hooves running down the outside of her hind legs... then back up the inside of her legs, sliding higher and higher. The feeling nearly overwhelmed her, eyes opening again as she gasped. “Starlight, what are you doing?”
“I am giving you a thorough and relaxing massage, Twilight Sparkle. Just like my marefriend taught me when I dated her.” Starlight continued to massage intimately close between Twilight's legs.
I should stop this. This is going too far. I didn't mean this kind of massage. Twilight hesitated, the feelings from the massage hitting her in ripples with each hoofstroke. I need to protect Starlight from herself, even if she said it was alright. Just then a new thought drifted through her mind, stopping the budding panic within her in its tracks.
If I really trust Starlight, I should accept her word that she truly is okay with this.
Twilight's cheeks grew red from embarrassment even as her muscles relaxed again. She eased back into the tender and intimate massage. “Starlight,” she said softly, turning her head to look back at her friend, ”continue the massage to the end.”
“Yes, Twilight Sparkle.”
“And once that's done,” she added, a hint of a smile touching her lips. “Show me what else she taught you to do after the massage.”
“Of course, Twilight Sparkle. I will show you all she taught me.” Twilight could have sworn she saw Starlight's smile grow a little wider, but the continued sensations washed away everything else.
I hope I did the right thing. Any further thoughts were cut off when Twilight felt her friend's lips brushing over her own, and moments later they were kissing deeply.
They were nearly at the four-hour mark when they finished. Twilight wobbled as she stood up again, catching her breath, acutely aware of the wonderfully warm sensation through her entire body. Leaning against the still form of Starlight Glimmer, she managed to keep her feet. “Wow, your old marefriend taught you a lot,” she murmured. Starlight gave no reply, simply standing until she received new instructions.
Glancing at the clock, Twilight sighed. “It's time for this session to end, Starlight.” She smiled, then stepped forward and kissed her friend warmly on the mouth. “You gave me a lot of data to study tonight.”
Stepping back, Twilight's horn glowed as she triggered the spells to release, freeing Starlight's mind and actions for the first time in nearly four hours.
Starlight drew a deep breath, smiling broadly at Twilight. She opened her mouth to speak, then stopped, her body shaking. “Hold me!” she managed to squeak before the shaking grew too strong and she lost her footing, falling toward the impromptu massage bench.
Twilight gasped and dove forward, catching her friend in her forelegs and guiding her to the bench, holding her close as she shook. “Starlight! What's wrong? Are you alright?” she asked fruitlessly. Starlight clung tightly to Twilight as another, stronger wave hit her, drawing a long, loud moan from her lips. She shook and quivered, her body at the mercy of the sensations.
Realization finally dawned on Twilight when the third wave hit and Starlight threw her head back, crying out even more passionately. “Are you... you are!” she gasped, holding her close as she writhed in pleasure.
Slowly, after several minutes, Starlight regained a little more control. Twilight held her close throughout, stroking her mane and whispering gentle words until she could speak again. “Thank you, Twilight,” she whispered, then kissed her on the lips briefly. “Thank you, thank you, thank you.”
“You're welcome,” Twilight answered, taking the kiss in stride. “What was all that about?”
Starlight looked chagrined, her cheeks still flushed a deep red from her pleasure. “When I come out of the spell, the sensations from being under the spell all come back and hit me at once. The longer I'm under, the harder they hit and... the more I orgasm.” She chuckled. “I probably should have mentioned that, huh?”
Twilight laughed along with her, nodding. “That might have been useful to know, yes. We'll work on your communication later, though.”
Starlight nodded, snuggling up close to Twilight. “Thank you for trusting me, Twilight, and for living up to my trust in you. I'm truly glad you took the opportunity to explore yourself alongside me.”
Twilight nodded and kissed Starlight's forehead. “I'm glad, too. I'm not certain how we'll deal with this in the future, but I'm sure we can work something out. It's not like-”
“Twilight?” Starlight looked up at her mentor, smiling softly. “Stay in the moment a little while longer.”
She smiled, cuddling her close. “As you wish.”
