"Suck me off."

Grinning, I unzipped my pants. "Well, Mandy," I said. "That offer about sucking my dick sounds good. Get on your knees and beg me to let you suck my cock."

A shudder went through Mandy as she dropped to her knees so abruptly I almost asked if she was okay. I figured that her robot knees could handle the impact. Kneading her breasts together, Mandy bit her lip. "John, let me suck your cock." she begged.

Rolling my eyes, I shook my head. "Is that it? That's your best begging? C'mon, Mandy, put your heart into it or you can just finger yourself on the couch for a while."

The idea of not being able to have me seemed to trigger the desired effect. "Master, let this unworthy slut suck your big fat cock! I'll do anything for it! I'll swallow, let you cum on my face, my clothes, my hair! Let me suck you, Master!" she screamed, squeezing her jugs so hard that I thought they'd pop.

Nodding to her, I grinned. "Now that's more like it. Go for it, babe," I said. Mandy eagerly fished my cock out from my pants, holding it delicately. Opening her mouth wide, she began sucking on it with gusto, taking it until my nuts touched her chin. I almost lost it then and there from her sheer enthusiasm. "Shit! That's one hell of a mouth on you, Mandy!" I complimented, making her moan.

I was lucky to last as long as I did under that frenzied cock sucking. Grabbing her head, I held it in place as I came into her mouth. She gulped loudly as she swallowed. Once I was done, I let her head go. Mandy leaned back, cum trickling from the side of her mouth. She seemed to be in a blissful daze.

"Oh, and Mandy? Don't call me "master". A simple "sir" or "John" will do," I said. I wanted a robo-slut, not a robo-****.

Licking some of the cum from her mouth, Mandy nodded. "Yes, sir," she whispered, her voice tinged with lust. "Sir...I think I came when I sucked your dick..."

I tsked. "Mandy, you never 'think' you came. If you only 'think' you came, you didn't. Maybe I'll have to show you what a real orgasm feels like."

Her eyes widened with excitement. "Oh, yes SIR!"
