Of course not!

"Oh, silly. It doesn't matter anymore what you think you want." Her hand slides down to your crotch. "From the moment I signed your cocksleeve documents, you became mine entirely, including your mind. I decide what you want, and I decided that you want to be my little cockwarmer." She grabs your dick, and balls in one hand, and looks at you severely. "Understood?" You gasp, before nodding. "Good." She loosens her grip, and smiles down at you.

"As a 'Sorry for making you pass out on my cock' gift, let me take care of that for you." She smiles slyly down at you as she unzips your pants, at which point you realise that you have a boner. Whether from fear, or arousal isn't quite clear to you, but what is, is that your mothers hand is absolute magic!

Silky smooth, strong fingers massage your shaft, warying their tightness in a wave like motion, occasionly joined by her thumb stroking up your head, almost sending you over each time, but she edges you like a pro, milking out pre, until she suddenly tightens her hold into a grip, and gives you three quick jerks, which bring you to a crashing orgasm, flooding her fist with watery cum.

In the afterglow of the best damn orgasm of your life, you don't even object when you mother brings her hand to your mouth, and commands: "Lick it." You just do it, your tongue playing over her palm, then fingers, worshiping her entire hand. With a wet pat on your cheek, she rewards you with a: "Good boy."

"Now, since you've decided to be my cocksleeve for life." She gives you a meaningful look. "I think it's only right that we make it a little more obvious, especially so that your sisters don't get any funny ideas."
