For a blowjob...

You smile and point to your crotch. "Take out my dick."
Samantha smiles and moves to obey, but you stop her by putting your hand on her head. "On your knees, no hands."

She keeps smiling and kneels before you, hands clasped behind her back. It feels a bit odd to be able to tell a woman what to do without pushing messages into her, strange as that might sound. Samantha frowns in frustration as she realizes that pulling down a zipper with your teeth isn´t as easy as it sounds. But she gets it right pretty fast. Then she reaches in and pulls down your underwear to reveal your semi hard cock. She then takes the tip in her mouth and looks up at you expectantly.

You´re a bit confused as to why she isn´t sucking it until you realize that she´s waiting for permission. As you nod, she starts to eagerly suck your cock. She´s a far cry from Kellys blowjobs, but you suppose she just lacks practice.
Samantha gags when you push more than two thirds of your length into her mouth, but she doesn´t get annoyed. Instead she looks up at you apologetically. She must really want to please you.
Samantha pulls her head back and works her jaw a bit, apparently sore. "Sir, can my jaw rest?"
One disapproving look is enough to get her back on your dick, sucking away like there´s no tomorrow. You decide to push more into her mind. {His cock tastes lovely} The thought slid into her mind without any resistance. Samantha moaned, pleased.
Despite not being as skilled as Kelly, you start to feel a familiar surge in your balls. You pull out and let loose over her face, splashing it and her glasses with cum. Samantha seems surprised but quite happy and start licking up some of the cum near her mouth.

"Thank you Sir." Samantha seems really excited, will you continue using her?
