I can do almost anything with this...

"Hey Stella, can I see my arm again for a moment?" I say.

She positions it closer to me.

I write Alex's Living Masturbation Toy on her arm, not sure what to expect before bringing her attention to it.

"Oh my god. I never realized I'm supposed to be your masturbation toy. I've been doing a terrible job. Let me know anytime you need me." She says.

"Any time? What if you're not here?" I say.

"Well, I'll try to get to you ASAP to be useful." She says.

Not exactly what I was expecting, but plenty good for my needs. Especially considering I'm rock hard now, even if her body is lacking in some of the areas I'd prefer.

"Well, actually. I could use you now." I say.

"Oh... Ok. I guess eating will have to wait." She says.

"Follow me to my room." I say, and she does.

I start undressing, and she just stands there.

"Ummm, I'm gonna need you to undress." I say.

"Ok." She says, and starts undressing.

"Why aren't you being more proactive in this?" I ask, a little confused.

"Well, I'm a toy, so you should be the one to use me, not me running things." She says.

Well, she has a point, alright guess I have to control her here, "Stella, mount me and ride me." I say as I lay back on the bed.

She goes to mount me, but she's dry as a bone, and it hurts as she tries to **** me in. Jesus.

"Stella, that hurts, stop." I say, and she does.

Do I need to go get lube? Wait...

"Stella, give me my arm for a moment." I say, and she complies.

I write Alex's arousal, and show her.

"I didn't realize you owned my arousal, my bad. I can't really control it though..." She says.

"No problem, whenever I'm using you as a masturbation toy, you'll be as aroused as you possibly can be until I'm finished using you, for everything else, you won't be aroused at all." I say.

Instantly, her nipples harden, and her eyes look at me with a mad lust in them, but she still does nothing. I begin rubbing her pussy until I feel it start to get wet.

"Ok, you can ride me now." I say.

I slip inside her, and this time, it feels amazing as she she rides me with gusto, as her insanely high arousal fogs her mind as her hips buck against me.

All the power and arousal quickly drive me to orgasm as well, spilling my load inside her.

"Alright, I'm done using you as a masturbation toy for now." I say after a moment as my dick begins to soften inside her.

Just as quickly as her arousal came on, it disappears, and rationality returns to her face.

"Oh damn, I'm gonna need to get some plan B." She says as some of my cum leaks out of her.

Seeing her like that gives me an idea...
