"I may go and play with my vibrator for a while," she said half to herself. "Not the same as a good hard cock though." Yeah, I suppose," I said only h...lf hearing.My sister and I were very close, having spent at lot of our growing up years like this, for our parents would go to bed so early and leave us all alone."You want to play something?" she asked."Yeah, sure, just as soon as I've finished this," I replied. "What time is it?" It's still early," she said cheeking her watch, "It only just. "Of course," said Sonya. "You can start by bringing us some drinks,slave," she added, giving me a slap on the butt."I yelped and said, "Okay Sonya"."That will be Mistress Sonya," she said sternly."Yes mistress," I complied meekly.After I got the drinks, the girls made me do a lot of chores, teasing meconstantly and trying to humiliate me. I was surprised by Sonya'stransformation. The quiet, sweet girl had almost transformed into afierce dominatrix.The girls made me kneel and paint their toe. Small, silent smiles and stifled giggles passed between them, but they all quieted immediately and snapped their eyes forward, looking over the girl standing opposite them, when a muted thud came from the far set of doors. Lacie, unsure of what to do, looked across the table, spotting Lindsey there. Lindsey stood, her arms demurely crossed in front of her waist. Her head was tilted back, displaying her black choker with the small ivory disk. Her eyes seemed focused on some point behind Lacie’s. While we hugged, I felt her tongue slip into my mouth and wiggle it's way around my tongue; I then felt my clothes dissolve away, melt away in a kind of magical erotic heat generated by an erotic spell she'd cast. Consequently, my dick slid into her pussy, even though there was no real action on my part or hers. It just happened. I softly pumped her juicy, hot, semi-tight pussy, then in a fit of lustful passion, I grabbed her thick, fat ass and rammed my dick continuously in her pussy, grunting.
