Cum inside of her

With your powers, it doesn’t matter where you cum. If you do impregnate Jill you can just wish it away, so, without any care whatsoever, you continue to enjoy your sister bouncing on your cock, and the music of her endless moaning from the pleasure your dick gives her. You never imagined that someday Jill would be moaning because of your dick, but your hot sister is right there, fucking you.

Finally, you reach your edge, and just as Jill comes, taking your dick fully inside of her one last time, you groan in pleasure and also come, filling your sister with your cum. It feels great to give her your full load, and it is clear she also enjoys it very much from the expression on her face.

After you both are spent, she collapses on top of you, exhausted. Your now flaccid dick pops out of her as she lays on you. After the hot sex, it feels great to have her resting on top of you, her naked breasts on your chest. Despite being a bit tired, you still manage to play with them a bit, massaging and groping her, playing a bit with her nipples, which elicit a few light moans from her. She then looks you, her face still showing the pleasure you gave her.

"Sorry, bro, I don't know what happened. I just really needed to fuck you. Please don't tell Mom, she'd kill me if she found out we had **** sex", she pleads while you just smirk. Poor little Jill, so worried about something that wasn't even her fault, and that won't have any consequences, even if your mom does find out.

"Sure thing, sis. But only if you let me fuck you whenever I want", you tell her, while wishing she will accept your deal. She seems to think about it for a moment before your wish has its effect.

"Of course we will. Now, how about round two later today?", she asks you with a lustful and mischievous expression on her face. You quickly nod at her question with a smirk on your face. The powers are just great!

After you go take a bath, you decide to have a bit more fun with your powers.
