If she stayed, she'd have more time to work on me." No, Mom, I'm not. I stood there in the doorway and heard the whole thing." You too. Night, Mom."I ...ook the phone from him and put it back on the headboard."How much of that did you get?" I think I figured out most of it. Especially the part where you said you realized you never should have doubted me and were going to dedicate your life to being my slave forever." Whoa, I didn't go that far. How about if I never write you off without giving. "You may be my older brother," she said, "but I'm in charge today."She looked deadly serious, so I replied, "Sure, sis. Whatever you say. Anything you want."She smiled as she mounted the bed, straddling my outstretched legs. My cock twitched with anticipation. My little sister was about to fuck me! She settled down on my rampant cock, her pussy lips flanking it and my helmet peeking out. Rolling her hips, she rubbed her amply moisturized cunt up and down against my shaft. I looked into her. Each girl has clothes on site with makeup and wigs and all kinds of sissy things.Panty-Sissy likes to dress slutty in lingerie and adores bras and panties. She has lots of different sizes and colors of bras. She loves to priss in her bras and has dd forms that giggles. She talks in a queer femmie voice saying she is a sisssy and she loves to suck cock. She holds a bra over her head and prisses around the room saying how queer and sissy she is while she wiggles her ass in her pink panties. She humped back for every thrust."Lower your head and shoulders to the bed and pull your ass cheeks apart," I directed. She obliged me.I replaced my thumb in her ass with my index and middle fingers. Mom was on her way to her third orgasm, which hit very soon, destroying my resistance."Keep your ass open," I instructed as she convulsed really milking my aching cock.I pulled my cock out of her pussy and my fingers out of her ass and started jerking over her gaping asshole. My come flew in jets.
