Liz got out of the shower, and I followed her to her room to get dressed. She went to her dresser and got out bra and panties. I stepped up behind her before she closed the drawer, my cock rock hard again and poking her in the back. I reached over her shoulder, grabbing all her underwear from her hand and the drawer.
"I told you, you are not allowed underwear anymore, ever. And no clothing at all in the house. Now get your uniform."
"Yes, master. I forgot master."
She put her work clothes on, which consisted of a fairly tight white blouse and a skirt that came to about two inches above he knees. I walked around her, checking her out. Her nipples were erect, pressed tight against the material of her shirt. You could even make out a hint of areola through the thin white fabric.
The skirt wasn't short enough for my liking. I grabbed the waistband and rolled it up three times. That put the bottom hem at about two inches below her ass cheeks. I told her to bend over at the waist. I stood behind her as she did so. I watched in great delight as the back slid higher and higher as she slowly bent double. When she placed her hands on the floor, her pussy and her asshole were plainly visible. It was more than I could stand. I stepped up to her and shoved my throbbing cock all the way into her glistening pussy.
She screamed as I grabbed her hips and started pounding her as hard and as fast as I could. I only had a few minutes before she had to leave for work, and I wanted her to go with fresh load of cum in her pussy. It took less than five minutes before I was grunting and erupting inside her deliciously tight pussy. She came at the same time, bathing my balls and legs with her slippery nectar. I pulled out as I finished and shoved my cock into her asshole before I went soft. I pumped her a few times before I was too soft to continue.
As my cock slipped from her asshole, I told her, "Now get over here and clean me off, slave."
She flipped around on her knees and looked at my cock in dread, she knew it had just been in her asshole. She swallowed hard, but then took my whole cock into her mouth. I spread my legs as she finished with my cock and moved onto my balls. She licked her own cum off my hairy balls and legs. When she finished, she stood up, licked her lips, and then wiped her mouth. I looked between her legs, I could see a trail of cum running down her leg, almost to her knee. She reached down to wipe it up, but I stopped her. I said, "Leave it. When I get to the restaurant with Heather, I expect to see the dry trail on your leg."
"Yes, Master."
"Good, now get to work."
"Yes, Master." With that she left for work.
When Heather got home two hours later, I was still naked. I was sitting on the couch watching the video of her sister, absently stroking my hard cock. At that point of the video, Liz was getting her asshole pounded by Kevin, and you couldn't see her face. Heather glanced at the screen, but all she say was a porno of a black man ass fucking a little white girl on a coffee table. She sat down next to me, grabbed my cock, and took over stroking as we watched.
"Gee, that girl looks tiny. Especially next to that huge nigger. And holy shit, that dick is huge. I wonder what that feels like. But anyways, what are you doing sitting here watching porn? Liz could be home anytime."
"Oh, she seems to be enjoying it, well enough. See, she's even got two fingers in her pussy. And Liz only went to work a little over an hour ago."
"Oh that's right! She switched shifts today. Hey! Why does it smell like sex in here? Wait a sec! That's my coffee table! Is that Kevin?"
"Yeah that's Kevin. I made this video earlier today."
"Where was my sister while you were doing this?"
