Warm streams of cum spurted onto my belly. I wiped it up with one corner of the towel, then wrapped it around me again and relaxed with my hands behind my head. I began to doze off.
I awoke to the sound of the shower. It was Cyndi, I figured, and she wasn't using her parents' bedroom. The door was open. I wondered if she wanted me to see her showering. I got up, still in the towel, and peered in. Sure enough, there was Cyndi's nude form, exquisite as ever, in the translucent glass. She stroked herself, soaping the cum off her tits, no doubt. I watched as she played with herself, obviously enjoying the time spent lingering over her breasts. I smiled and lay back down on the bed. Cyndi came out of the shower and wrapped herself in a big black towel. She walked into the room, smiling at me.
"How was my performance?" she asked.
"Gratuitous," I said. "It was great. You certainly showed yourself to be the slut you are," I sighed.
Cyndi looked shocked. "What do you mean? Are you mad?"
I shook my head nervously as Cyndi crawled on top of me. She pressed her hand against the bulge in my towel-I'd gotten quite hard watching her. She kissed my face gently.
"I'm sorry, Ian," she panted. "I'm sorry I'm such a slut. I just… I guess I just need it. I need cock. I need lots of it… I'm sorry can I make it up to you?"
Cyndi's gentle touch had my cock shiver with pleasure. She climbed between my legs, letting the towel fall away from her nude body. I caught my breath as I saw her freshly-showered naked form. Cyndi tugged my towel open and exposed my long aching dong. I felt her warm breath against it.
"I'm sorry, Ian… really please forgive me. I'll make it up to you tomorrow night. I'll let you do whatever you want to me… kinky things… dirty things…"
"Nah," I said, panting heavily as I felt her warm breath on my cock. "I don't want-"
"Please, Ian," she begged. "I want you to do strange things to me.
Please? Anything you can think up that you'd like to see me subjected to. Make me do it."
Cyndi touched the upper head of my cock with her warm lips. I let out a sigh as I felt her tongue grazing the flesh. "Promise me, Ian?" she asked. "Subject me to your every kinky desire?"
"Oh yes," I groaned as Cyndi took my cock into her mouth. She pressed her lips around the head, licking off the smeared pre-cum. Then she slid it quickly down her throat, sucking my cock into her mouth until her lips pressed around the base and her tongue seethed up and down the whole length. Cyndi began eating me hungrily, forcing her head up and down so that my cock went in and out of her mouth. She gave me head good and hard, quickly bobbing her whole body in time with my cock as it went in and out between her lips. Cyndi began to whimper and squirm as she sucked my cock, groaning as I began to cum. She made me cum so fast this time-I really wanted to cum in her mouth. Streams of hot jizz flooded her mouth, and Cyndi swallowed obediently as I finished inside her warm mouth.
Cyndi took my cock out of her mouth and slithered up my body, easing the two towels out of the way. She lay there, her naked body pressed to mine, and rubbed her tits against my chest suggestively. "I want to ask you something," she panted into my ear. "I want you to fuck me. Will you fuck me, Ian? I deserve it… I've been a very bad girl. I've been a horrible slut. Will you fuck me… but not in my cunt. You should fuck me in the asshole for punishment. Make me take your cock up my asshole-force me to pleasure your long rod. Subject me to the humiliation of having you cum in my anus."
Hearing Cyndi talk like this was making me really hot. My cock was hard all over again, and I am really ready to put it in her asshole. I slowly pulled her off of me, getting to my knees as I eased her into a doggy-style position. She loved getting fucked this way-it would be anything but punishment. But the mere idea of her begging me for it made me horny. Cyndi whimpered and moaned softly as I got behind her, pressing my cock between her cheeks. I began to lean forward, her tight ass embracing the head of my cock.
Then, with one hand thrust, I penetrated Cyndi's asshole.
"OH!" she gasped as I entered her. She began to grunt in time as I butt-fucked her. I worked my cock in and out of her, and it felt incredibly good. I started fucking her faster, and then an idea came to me. This one really might be humiliating, but I was willing to try it!
I reached back and got the candle out from under Cyndi's pillow. I lifted it to her face and she moaned in pleasure as she started licking it. She worked it slowly in and out of her mouth, sucking on it as if it were a cock while I pounded my organ in and out of her asshole. When I knew she was nearing an orgasm, I took the candle away and slid it down between her legs.
"Oh… oh yeah!" she gasped as I plunged it into her cunt. I kept fucking her up the ass as I put the candle into her cunt rhythmically.
She worked her whole body against me, intensifying the pressure of my thrusts as I entered her again and again. Cyndi began to gasp and moan as I boned her up the ass and stuck the candle into her twat. I let the candle slide out as I got ready to cum. I butt fucked my sister faster, groaning as I felt my cock swelling up with fluid, ready to spew into her. I fucked her harder and better and then, with a loud groan, I let my cock go. It spurted a thick gush of my juice between Cyndi's asscheeks, filling her up with savory semen. As I climaxed, I gripped Cyndi's ass, pressing her down onto the bed so that I could lie on top of her.
I sighed, relaxing into the bed with her as I tugged my cock out. I lay on my back and Cyndi lay on top of me, kissing my chest.
"I want you to do that to me every night, Ian, as punishment. I want you to punish me for being a slut by fucking me up the ass. Do you promise?"
"You got it, Sis."
"All right-oh!" There was a knocking at the far door of the bathroom.
She kissed me on the lips.
"Be right there," called Cyndi. "I'll be right up."
"All right," came Doug's voice. I looked up at Cyndi.
"I told them I'd be right back," said Cyndi. "I promised them. They'll be so disappointed. You don't mind, do you…?"
I just stared up at her gorgeous tits, with their flushed red flesh and their hard pink nipples jutting out.
"I'm sorry, Ian," she said, kissing me. "I promised them!"
She got off the bed and bounced out into the hall, then up to the big bedroom.
I sighed as I looked down at my cock. It was starting to get hard again as I thought about what a slut my sister was.
I guessed I'd have to take care of this hard-on myself.
Chapter 9
Megan showed up that Tuesday wearing a torn jean skirt and a garter belt with fishnet stockings. The skirt was practically nonexistent at this point, with huge gaps that allowed me to see the smooth lines of Megan's gorgeous legs. On her top half she had a tight white tank top and a black leather jacket.
As she put her stuff into the spare drawer I'd cleared out for her, I lay on the bed and watched her luscious form moving. She was telling me about her affairs of the past week-whenever Megan went home, she got laid. She and I had a completely open relationship, so I didn't feet jealousy but only a vague arousal at the fact that Megan was getting balled and I was, too.
"Anyway, you remember Johnny?" she asked as she put some lace underwear into the top drawer. "He came on to me while my parents were home, and I ended up in bed with him, hoping they wouldn't hear the banging as we fucked. It was great. How was your week?"
I chuckled. "I'd like to tell you, but I've got a better idea," I said.
"How'd you like to watch a videotape?"
Megan stopped what she was doing and looked at me. Her dyed black hair looked very sexy against her white face as she smiled and licked her lips. She winked.
"That's kinky," she said. "Who with?"
