Why not help them out?

For a moment, your dirty mind conjures up a fantasy of both your children nude and having sex with each other. All of a sudden, you are filled with a desire to see it happen in reality. You focus your **** powers on Meilsa and whisper, “You want your breasts touched.”
Meilsa then stops kissing Rowol and says, “I want my breasts touched.”
Rowol, a bit surprised asks, “Are you sure?”
Meilsa blinks two times and then says, “Yeah.”
After that, Meilsa grabs the hem of her shirt and pulls it up, exposing her chest. She is still wearing a white bra though. Rowol then places both his hands on his sister’s boobs and starts massaging them.
“Oh wow.” Rowol says. “They feel so soft.”
“Thank you.” Meilsa says shyly.
You have no doubt that having a pair of boobs in his hands caused your son to have a raging erection. Let’s help him out with that.
“Ask her to touch your dick.” You whisper as you focus on your son.
“Can you touch my dick?” Rowol asks his sister.
“Uhm, ok.” Meilsa responds.
You had been prepared to do another mind trick on Meilsa and push her to be fine with it. But apparently, Meilsa already has an interest in her brother’s dick. While using one hand to keep her shirt under her chin, Meilsa brings her other hand to Rowol’s crotch. There she opens up his zipper and pulls out his fully erect dick. Next, she wraps her blue fingers around his human penis and starts masturbating her halfbrother.
“Oooohhh.” Rowol moans.
“Am I doing it right?” Meilsa asks.
“Yes, very good. Keep going.” Rowol says.
Then your two kids go back to kissing.

As the kids continue making out, Rowol becomes a little bolder and pulls Meilsa’s bra aside. You watch as her reveals her blue breasts and nipples and then he sucks on them. Meilsa then leans back, giving him better access to her boobs. But Rowol pushes her further and further until she lays with her back on her bed. After that Rowol becomes even bolder and slides his hand under Meilsa’s skirt.
That is when Meilsa stops him and says, “Rowol, we can’t.”
“Why not?” Rowol asks.
“It’s too fast.” Meilsa complains.
That is when you step in with your mind trick and whisper, “You’ll be gentle.” To your son.
“I’ll be gentle.” You and Meilsa hear him say.
Immediately after that you send a command to Meilsa as you whisper, “Then he can go all the way with you.”
“Then you can go all the way with me.” You and Rowol hear her say.
After that, Meilsa grabs her skirt with both her hands and pulls it up, exposing her white panties to her half-brother.

You quickly focus on both your children and whisper, “Pretend like I’m not here.”
Both your children then say in unison, “I will pretend like you are not here.”
Once they have repeated your command, you walk into your daughter’s room and stand in front of them. Neither of them acknowledges your presence.

Rowol then reaches with his hands towards Meilsa’s hips. There he grabs her panties and starts slowly pulling them down. You watch as your daughter’s blue pussy gets revealed. Seeing both her exposed pussy and boobs, you can only marvel at what a beautiful woman your daughter has grown into. No, she is still a girl. But thanks to her brother’s help, in a few moments …
Once Rowol has pulled off Meilsa’s panties, she spreads her legs for him. Rowol then takes place between his half-sister’s legs. He takes his dick and guides it to her pussy. Meilsa looks up into her half-brother’s eyes, unaware that she shares her father with him. You take out your own erection and start masturbating at your children’s impending deflowerment. Both your children gasp when their genitals connect. Rowol gently pushes inside Meilsa, just like you ordered him with your **** powers. With every gently push his dick goes deeper into his half-sister. Meilsa, in the meantime, lets him push inside her. After a while, Rowol pushes one more time, and then his dick is completely inside Meilsa’s pussy.
“Thank you.” Meilsa says. “For being gentle.”
“Thank you.” Rowol replies. “For letting me.”
The siblings then kiss and Rowol starts fucking his half-sister.

As you masturbate to the sight of your children having sex, you can’t help but feel some pride at having helped them transition from boy and girl into man and woman. Rowol thrusts into Meilsa over and over again. Starting slow but gradually going faster. Meilsa wraps her arms around his chests and pulls him close. Neither of the two care that they are still mostly clothed. You watch Rowol play with her boobs and hear Meilsa moan in pleasure. Rowol picks up speed and Meilsa pushes her hips up to meet his.
Suddenly Meilsa announces, “Rowol, I’m so close.”
“Meilsa,” Rowol announces. “I’m going to cum.”
