Have her masturbate

You concentrate very hard and think,Ignore my prescence. You then walk in front of a man and he doesn't notice you. You now know you can affect an entire area with your powers.

Anything that naked woman does is acceptable.

Then,turning to your now naked sunbather, you think one thing.

Masturbate.

The blonde begins massaging her clit,and the other beachgoers seem not to notice.

Your pussy is now twice as sensitive.

The womans moans get louder,and her finger-fucking speed increases. You take out your cock and begin to jerk off as well. The woman looks to be on the brink.

You are unable to orgasm until I do. When that happens,you will have the most intense orgasm of your life.

You and the blonde are now pleasuring yourselves at the same time. You can't hold it in any longer after about ten minutes and cum,causing your subject to do the same.

Now,go back to sunbathing.

THe woman,still naked,does just that.
