Ristan thought and asked "I've got an idea or two. Can you change gender?" You took a look at the chronivac and cycled through with your magic control. You pumped in a decent amount of magic and you felt your body shrink into the couch a little bit as your proportions started to shift. Your dick shrunk away to nothingness, you grew some B-cup breasts, but considering you were wearing your baggy robes the changes weren't that apparent for your roommates. The biggest thing was your face getting cuter, and your baggy robes getting slightly more baggy. You regripped the chronivac in your smaller hands staring at the daintier smoother things.
Kalzbin said "Well I'll be, that thing actually works."
You said "I lit up the ceiling in magic lights!"
Kalzbin said "Too be fair a wand could do the same, I haven't heard of a mere trinket that could change your body like that though." Then suddenly you felt a dull ache at your groin, and then felt kinda horny. You felt your heart pounding and a warmth come over you and then Ristan who was sharing the some couch as you got up and walked in front of you. As he came into line of sight all those feelings intensified as you just felt like you needed him, and would do anything for him... All for just a little "companionship".
Ristan leaned in and asked "So you can feel my Incubus charm?"
Half moaning you replied "yes..."
"So you indeed are female?"
"yes..."
"Interesting, now please follow my instructions."
"yes...."
"You know how to imagine your pool of mana right?" Ristan asked as he put a finger on your gut "Just a pool of energy, perhaps something looking like a pool of pure water." you nodded the feeling of his indirect touch moistening your crotch as he continued. His finger slowly inched up as he said "just imagine using some of that pool to dig a channel upwards... Like how a river might carve itself through a canyon over millennia following my finger." and you did, the pleasure of his touch made it real easy to concentrate on moving the center of your magic towards it. Ristan moved his finger slowly and carefully, and when he reached your chest he was careful to go through the canyon of what cleavage you had careful to try not to touch them too much. A part of you was sad he hadn't fondled them and made you make a pool in either of them, but you still loved his simple touch. Slowly but surely he went up your neck, over your chin, past your lips... The scent of his fingers were... well it was the scent of the sauce they covered the phoenix wings in, but it was all the better as it was coming from Ristan. Once his touch went between your eyes and stopped at your forehead his teachings continued "Now that you have a river to your brain imagine the pure water of magic to coat it, allow it to go around, and have it repel whatever magic may try to be tampering with it..."
It was euphoric to do what he was asking... Until it wasn't. As you completed his last request the horniness was gone. It was just a really handsome guy with a finger on your forehead after he had just touched a decent amount of your body. Your face having been slightly flushed from magically induced hornyness flushed further in embarrassment as you kicked him off. As he crashed to the ground you dashed behind Kalzbin and asked "The heck did you think you were doing?!?"
Ristan groaned and said "Helping the alterer of reality and archmage be able to protect their mind."
"Why didn't you just tell me?"
Ristan said "This way got you more focused, and you would actually pay attention to my suggestions instead of flat out denying them." the incubus smirked and said "Well if you really want a ride just ask, but there was a plan I actually had."
You asked "What's the plan?"
Ristan said "I'd like you to swap my gender as well so we can enjoy a ladies night at a few bars I know tonight. Kalzbin could swap his gender too if he wants." Kalzbin blushed a bit as he considered... Trying being a female minotaur. "Those bars hate my kind being around on a ladies night, but from some Succubi sisters I hear bars will do nearly anything to keep one near the front of a bar... Say can that thing do clothes too?" you nodded and then noticed your robe had been the same and if you wanted to ladies night bar hop it might be best to at least have a different set of robes.
