He spent the new week or so unlocking spells and coming up with new ideas of how to use each one. Vex had helped him pick and choose which spells would help him achieve his goals. He still needed far more power if he were to unlock the spells that would allow him to control Ruby, but that was alright for now. In the mean time, he had been devising a way to fuck Anna. According to Vex, that would be much easier than trying to totally dominate someones mind and body.
Using the spy spell, he had found Anna was incredibly boring. He'd watched her do yoga and even spied on her in the shower. Sure he had been excited to see her naked, her new younger body was exceptionally hot, but she hadn't done anything particularly interesting. As far as he could tell, she never masturbated or did anything remotely sexual. Vex had offered a solution to that.
It was another spell much like the one that was currently making them walk around in their underwear, something Ethan was enjoying immensely. Except this was one of Vex's own creations. It would increase the arousal of anyone within the house, except the person that cast it. She explained while it wasn't much of a problem with this spell, stronger ones needed to leave the caster unaffected or else they'd become overcome with lust and be unable to think, usually causing them to die by starvation.
He activated the spell just before dinner, he wanted to see the results. As he went downstairs he didn't notice much difference, the two women were sat talking and waiting for him as usual. As he ate though, he noticed they both seemed slightly distracted, shuffling slightly in their seats. As soon as they were done, they both excused themselves from the table, Anna asking Ethan to tidy up before quickly leaving the room.
He cleaned up as fast as he could and ran upstairs. He activated the spy spell with a strand of Anna's hair he had retrieved from her bathroom. The image appeared in front of him, showing Anna laid on her bed with her hand how hair panties and her breasts pulled free from her bra as her other hand tweaked her nipple. It was one of the hottest sights Ethan had seen, his usually innocent and friendly step mother rubbing her clit with a desperate look of need on her face.
Part of him wanted to go in there right now and fuck her brains out, but Vex reminded him that wouldn't be a good idea. While the spell increased her arousal, it did nothing to change her feelings about fucking her step son. She did point out however this may be a good opportunity, but first he had to check on Ruby. He ended the spell and restarted it with Ruby's hair.
She was on her own bed, her panties discarded and her legs spread wide as she fucked herself with a bright pink dildo. Ethan hadn't seen that before, he didn't even know she owned it. He watched as she plunged the toy in and out of her soaked cunt while rubbing her clit with her free hand. He was tempted to stay and watch, but Vex reminded him he had another goal.
Sneaking quietly along the corridor, Ethan stood outside Anna's bedroom door. He could hear quiet moans coming from inside and his cock grew even harder. With his heart racing, he placed Vex on the floor by the door and fished his cock out of his pants. He began to stroke it, listening to Anna moaning inside, timing his strokes with the sounds of her pleasure.
The sounds of her moaning grew, Ethan wished he could have brought the bowl with him so he could watch her as she brought herself closer and closer to orgasm. Instead he pictured her, imagining her on her bed with her fingers buried deep inside her wet twat. As he heard her moans becoming more frequent, he sped up, timing his orgasm with hers. He heard her squeak and obviously suppress a loud moan as she came and he stroked himself quickly, blowing his load into a t-shirt.
He took a moment to catch his breath before hearing a thump from inside her room. Quickly and quietly he returned to his room and closed the door. He glanced over just in time to see Ruby shuddering in orgasm, her legs slamming together and trapping her hand between them and keeping the dildo inside her as she trembled in pleasure. It was enough to make his softening cock twitch in arousal. He watched her for a few moments until she relaxed and began to get up and he killed the spell.
"That's much better," Vex purred from inside the phone.
"Did it work?" Ethan asked.
"Yes, you were close enough for your souls to interact, it wasn't a huge amount of power, but maybe five times more than if you were alone?"
Ethan smiled. Vex gaining power meant more spells for him to learn. He still wasn't sure if she really needed power to show him spells or whether that was just her excuse to make sure he collected her more and more power. Either way he didn't care, as long as it helped him.
"How about we try manipulating Anna's mind?" Vex suggested.
