We’d returned from the funeral for my wife’s grandfather. He’d been sick for a long time and Charlene had been at her mother’s place helping care for him for a few months. In the meantime, her sister, Sheila, had continued to live in our little house-behind-the-house servant’s quarters home. She went to a trade school and couldn’t afford her own place. I discovered that Sheila had stolen some silver dollars, gifts from my dad, to fund her speed addiction. Charlene was so pissed she gave me leeway to do whatever I wanted to her. “Slap her, fuck her, kick her out, I don’t care” were her exact words. I chose to fuck her.
Since it was supposed to be a punishment, I stepped out of my usual self and became dominant over her, something that seemed to agree with her. Sheila had had sex only twice before, straight missionary with the same guy. I introduced her to rough, unlubricated anal, I came in her mouth and forced her to swallow by plugging her nose and pinching a nipple so hard she cried out, then had to swallow to inhale. We continued to have sex afterward with me pushing her into new, hopefully uncomfortable, scenarios intended primarily for my personal satisfaction, although I always made sure she came at least once each time.
She masturbated for me a few times, following my instructions to do what I wanted to see. She’d gotten used to her own flavor and even sucked her fingers clean after an anal bate. Swallowing my cum had become routine and sometimes seemed like she wanted it. But she never slept in bed with me. After our sessions, she always went out to the couch and slept there. If she ever wanted to masturbate, she had to let me know for permission. Sometimes I watched, sometimes not. She was my sex slave and performed the role well.
The day after the funeral we got home a little past noon. I reminded her of my edict that she always keep her cunt and ass clean, then Charlene and I rutted like animals in our California king waterbed because Charlene hadn’t had dick in a few months. When we were done, I heard Sheila bating on the couch. Scooping some of the semen/nectar combo from Charlene’s pussy, I snuck out to the couch and slipped it into Sheila’s mouth before she realized what was happening. After she’d cleaned my fingers, she did the same for my dick while continuing to masturbate and orgasmed in the process. I wet my fingers in her cunt, walked over to Charlene who was standing naked in the doorway, and slipped them into her mouth. She cleaned them with her tongue as if it were her own pussy juice on them.
Now, here we are, about an hour later. Charlene and I are in bed, still naked. We dozed briefly, then woke and cuddled. I was really wanting to have them both together.
“How do you feel about having Sheila join us,” I asked softly, in case Sheila was awake. There were only strands of beads across the opening from our bedroom to the living room.
“You really want this, don’t you,” Charlene asked back. I replied affirmatively and waited. She rolled onto her back and stared at the ceiling for what seemed to be a long time. “We’ve done some freaky shit before, but nothing on this level,” she mused. I wanted badly to say things to convince her to agree but knew that wouldn’t have the desired result. So I continued to wait. Rolling back onto her right side to face me, she asked, “Do you want her and I to do things together, or just attend to you?”
“Both,” I replied. Just the idea of them in 69 and both sharing my dick with their mouths caused me to grow.
“Mmm, yeah, I see,” she mused, looking down at my crotch. She lightly gripped my shaft, giving a few strokes, then let go. That brought me to nearly full hardness.
“I’ve been thinking about this since you mentioned it in the car. Surprisingly, I find the idea arousing. The taboo due to the risk of knocking up a blood relative makes sense, but if that’s not a problem, I don’t see why not.” You could have knocked me over with a feather when she said that. “Do you think she’ll go for it?”
“I think there’s a good chance she will,” I replied. “Your little sister is somewhat of a sub. So far, she’s been quite compliant with my wishes, no matter how kinky. It might be that she’s just scared of being kicked out and having to leave school, but I’m strongly suspecting it’s in her nature.”
Charlene lightly stroked my stiffened cock again. “I’m guessing you’re ready right now.” With a light giggle, she continued, “Let’s do it.”
“Sheila,” I called. “Come in here.” I spoke with the expectation of being obeyed. Charlene’s eyes widened a bit in surprise.
Sheila moved partially through the bead curtain and paused, staring at Charlene’s hand stroking my cock. Her face reddened. I wondered if she had an idea of what was coming, or cumming.
“Undress and join us,” I said firmly. Charlene’s hand tightened on my cock.
“You’re fucking crazy,” Sheila said and turned to go.
“And you’re out on the street, bitch,” I snapped. Charlene’s hand released my cock. I later found out that she did that in case I wanted to jump up and get physical with Sheila. That hadn’t crossed my mind, since Sheila had been so compliant up until now.
Sheila stopped, waited for a moment, sighed heavily, came fully into the bedroom, and began stripping. When her clothes lay in a pile by her feet, she looked at us and asked, “Where do you want me?” The shock on Charlene’s face was barely noticeable, but there.
“Move over a bit, hon,” I said to Charlene, indicating she should move further onto her side of the bed. I moved to the middle and patted the vacant area to my right. As Sheila moved around the foot of the bed, I took in all of her nakedness. “I never get tired of seeing your body, Sheila. You are fucking delicious.” She blushed again, probably wondering what effect my words were having on her sister right there next to me.
“I’ve never seen you naked like this, sis. He’s right. And I know you taste sweet as honey,” Charlene chimed in. Oh, fuck, this was going better than I could have imagined.
The bed sloshed as she lay next to me on her back, as she usually did. I wondered if that was a part of the submissiveness, sort of a “take me” surrender position. “Now what,” she asked.
Fuck, I was tired of being the boss. I wanted someone else to run the show for a change. “I think you girls should figure that out between yourselves. You can start on me, or if you want to start on each other, I’ll move out of the way.” That brought an “urp” sound from Sheila and a satisfied “mmm” sound from Charlene.
Charlene grasped my hard shaft and gave it a couple of strokes, moving the foreskin down and up, covering and revealing the swollen head. Sheila watched, face still bright red. Oh, her horizons were going to expand even further today. I would have loved to have been a fly on the wall inside her head.
“I want to watch you suck him, sis. Suck my husband’s dick. He says you’re a natural.” Sheila looked at Charlene for a moment, then rolled onto her left side and moved her head down, engulfing my cock with her mouth. For someone with little experience, she’d turned out to be a hell of a cocksucker, just like her sister.
Charlene continued her grip on the base of my cock as Sheila’s mouth slid up and down, tongue working on the shaft, head and glans. The head reached her throat with about an inch of shaft remaining. I’d tried pushing further, but she had a wicked gag reflex, much stronger and persistent than Charlene’s. Charlene and I had tried it several times, spurred by the popularity of the movie Deep Throat, but without success. I would have enjoyed it, but not at the risk of being puked on in bed.
After a few minutes, Charlene said, “My turn.” She pushed her sister’s mouth off my dick and took her place. Sheila lay there, elevated on her left arm, watching. The redness had left her face, and I could hear her breathing was deep and slightly ragged. Damn, she was turned on.
