I stood on my dock sipping a cup of coffee as I watched the boats cruise up and down the lake. It had been 3 days since the girls had shown up in my boat house and they had finally been reported missing. I saw Tim in uniform, maneuvering his bass boat over to me. There were two volunteers sitting in the bow with binoculars scanning the shoreline.
"What's the hubbub about?" I asked in an innocent tone.
"We're looking for four girls who were camping on the other side of the lake last week. Looks like they got caught out in that storm and their canoe capsized." He replied, like he had probably said twenty times already.
"Find anything?" I asked in return.
"A couple of life jackets, and their canoe was washed up about two miles down the lake so it doesn't look good." He replied somberly. "We are combing the shore to see if any of them made it, have you seen anything?"
"Nothing worth while, but I haven't been down here since before the storm." I replied.
He nodded to me, then gestured over to the boat house. "Any sign of activity around your boat house?"
"Not since last month when I had to call you to get those kids out after they had shot up all those drugs. Keep it locked now" I replied.
Tim laughed, "Oh yeah, I remember them. Their parents were really appreciative when I let them off with a warning."
"Why don't you come over after work. We can catch the game and talk about all of the other stuff that has happed in that boat house lately." I called out as his boat pulled out. He gave me a thumbs up and turned to motor further up the lake.
I gave it a few more minutes then headed back up to the house. I gave a quick scan to make sure that no one was coming up the drive or the path to the lake, then locked the door behind me. I set my cool coffee cup on the counter and headed down into the basement. I opened the door to the dungeon and flicked on the light, the sound of muffled moaning stiffened my cock in my pants.
The first shipment of my order had finally come in and I wasted no time putting it to use. Both girls were on their bellies laying on sleep pads in the middle of the dungeon. Thick leather cuffs were wrapped around their wrists and ankles, then fastened together to pull them into a tight hogtie. Ball gags filled their mouths and stifled the moans that the vibrators shoved in their pussies were forcing out of them. They looked up at me, eyes filled with both discomfort and frustration as they had been in that position for a good hour. The vibrators were set on low and a steady thrum of pleasure inducing stimuli had been their only sensation in the darkness.
I moved over to where they lay and crouched down between them to run my hand along their sweat slicked shoulders and down their back. They arched against my gentle caress, and flinched as I slid my fingers between their legs to feel their arousal. I gently pushed the vibrators deep into their cunts and watched their hands clench in fists of frustration. The only sounds that escaped the mouth filling gags were deeper and louder moans as I gently flexed my fingers, allowing the vibrators to slide in and out of their wet pussies.
I moved in front of Erica to look into her eyes. She stared up at me through her sweat damp curls, breath coming in rapid gasps through her nose.
"You must be feeling pretty turned on right now, am I right?" I asked. She hesitated, then reluctantly nodded her head. She couldn't deny how wet my fingers were after even that incidental contact with her cunt.
"I am guessing you want to cum, don't you?" Another, briefer hesitation and another clear nod of the affirmative.
"Well, we have a bit of a problem then, but you may be able to help me out." I said, and stood to unclip their legs. I pulled both of them to their feet and they staggered unsteadily with the vibrators still stuck deep inside them. I pulled the toys out and the girls let out groans of both relief and frustration.
"Don't worry, we aren't done yet. We just need to move to a more suitable location." I told them and guided them out of the dungeon and up the stairs to the master bedroom. I stood Erica in the corner where I could keep an eye on her, then laid Monica on the bed. I unclipped her hands from behind her back and secured her to the straps that I had fastened to the bedpost. Securing her legs to the other straps she lay there, spread eagle and vulnerable. I caressed her cheek around the strap of the ball gag while I looked into her eyes.
"You want to cum too, don't you?" I asked in a gentle but firm voice.
Monica glanced at where her step-sister stood, then back to me and softly nodded, giving a tiny moan of affirmation.
"It's nothing to be ashamed of" I said. "You and Erica have been through the same thing and she already admitted it." I slid the vibrator back into her still damp snatch and turned it back on to low. She groaned in frustration and I saw her grind her hips as the familiar stimulation took hold of her again. Her eyes slid shut and her tiny fists clenched as her arousal started to build.
I stood up and moved over to Erica, taking her by the arms and guiding her to the foot of the bed. I moved in behind her and held her close to me as I whispered in her ear. "I know you want to cum, and I know that you want me to make you, don't you?" She whimpered in despair but nodded in reply, gently pushing herself back against me.
"Well, it isn't fair now is it. That will be what, three times for you and none for poor Monica here." I told her as I slid my hand up her stomach and gently squeezed her tit. She groaned in reply, breathing deeply and pushing the fleshy mound into my hand.
"Monica told me what her father did to her, and I am sure she told you as well hasn't she?" I asked and Erica mumbled into her gag. I reached up and unfastened the buckle, pulling it gently from her mouth.
"Yes Master, she told me. The bastard tried to hurt me too which is why he is in jail now." Erica replied, stiffening as she did so.
I nodded over her shoulder, my eyes on Monica as she squirmed on the bed. I reached around and grabbed Erica's other tit, rolling her nipple between my fingers and feeling it stiffen in response.
"Monica is not ready for me." I said in a reassuring voice. "If I were to give her what I have given you, it might damage her even more. That is why you are going to do it for her."
Erica stiffened in shock. She turned her head to look at me over her shoulder. "No, I can't." she said breathlessly. "She's my...."
"She is your sister; I know you said so." I interrupted with a firm voice. "But she isn't your sister, is she?" I took Erica by the chin and gently but firmly turned her head back to look at Monica who was oblivious to what was going on. The bound girl writhed on the bed, moaning into her gag and straining against the chains that held her in place as the vibrator hummed relentlessly in her snatch.
"I have seen how you have acted since you got here, and can guess how it has been for you lately." I whispered into Erica's ear. "Watching her as she changed after practice. Catching glimpses as she ran from the shower with only a towel on. Those sisterly hugs that last just a little too long, and not long enough."
Erica said nothing, but made no move to look away from watching Monica on the bed. I could feel her breath starting to quicken as I talked and I felt her hands clench where they were bound between us. I traced my fingers down her belly and gently rubbed between her legs. She moaned softly, and pushed back against my questing fingers.
"It is alright, Monica is an incredibly hot girl that you have lived with for years. Now you are both trapped here. Prisoners of a bad man, aren't you?" I grabbed her tit, squeezing hard enough to startle her but not hard enough to hurt. She squeaked in surprise then nodded. "Yes" she said breathlessly. "Prisoners of a bad man."
"And you want to protect Monica, don't you? You don't want the bad man to get angry or he might hurt her."
Erica nodded again, and I saw her tongue flick out to lick her lips. I reached down and unclipped her cuffs and then taking her by the shoulders moved her toward the bed.
