“Quick, quick, quick!” I huffed down at my daughter as she sucked me off. It had taken little effort on my part to get her do this, though I hadn’t planned it to happen and she certainly hadn’t. We’d picked her cousin Kathy up at the airport with Lily and Andie in tow, then planned to drop me off her at the hotel. Kathy had begged to see my room, clearly impressed by the big hotel lobby. Like the other girls had done before just a few hours ago, Kathy admired the room like she’d been led into a palace. All four were on the king-sized together, getting to know each other, which was when I’d lured Mandy into the bathroom.
Neither of us said a thing as I closed the door, a bit confident now that Lily and Andie would keep Kathy busy and distracted for a time. I kept telling myself this is crazy as I gazed down at my beautiful daughter as she bobbed her head up and down on my cock. It wasn’t the thrill of doing in this secret that aroused me so much, it was just proximity of so many sexy girls, particularly of one who so clearly wanted my cock. “You going to swallow ... going to swallow...” I begged to know as I panted, getting firm nods of yes out of her now.
I quickly lost track of time and etiquette as my climax grew. “You fucking will swallow it ... be a good girl!” I demanded in a mean tone, “Don’t you spill a fucking drop ... ahhh ... fuck!” I barked down at her before realizing how loud I was being. She intensified her sucking at this point, despite my efforts to cram every inch of my cock, along with my balls down her throat. “Acccckkkk ... accckkkkk...” she kept chocking but wouldn’t give in as if egging me on even more. I pulled out and slapped her face hard with my hand, then my cock.
SLAP! “Mmm,” she moaned with a surprised look on her face, but then quickly again swallowed my cock. “Accckkk ... ackkkkk...”
“AHHH!” I grunted loudly as I shot down her throat as I forced her by the hair to not let my cock slip out an inch. I was defiantly getting a lot meaner, I warned myself. “Mphhh ... mphhh...” sounds came out of her now and I absolutely revealed in them. I nearly collapsed to the floor then, worried now that I’d made too much noise. There wasn’t much of a mess thankfully, but a stream of saliva and cum was threatening to drip off her chin, so I quickly scooped it up on the tip of my cock and fed to her like you would a toddler. She swallowed it normally now, several times before smiling up at me with an excited look on her face. I wished so badly for the stamina to bend her over and fuck her fast, but I didn’t have it.
“Up ... best sneak out,” I suggested as I pulled my pants up and cracked open the door. The room was largely silent, which worried me, but then my daughter slipped under my arm and began a conversation with her cousin as if nothing had happened. I caught a glimpse of Lily, who winked at me, letting me know that at least someone had realized what I’d been up to. Thankfully, Kathy didn’t appear to! I came out only after I’d heard them leave.
I lasted maybe two hours in the hotel alone before deciding I could make up an excuse to drop by the house and check on my girls; all girls maybe! I arranged for a rental car to be delivered as I was tired now of depending on Andie for rides; damn cute girl, but still a gatekeeper. It was late evening by the time I got to the house and discovered I’d unfortunately drawn a bad card from the deck of sex; it was Sherel who answered the door.
“Hitting it a bit hard aren’t you Frank,” Sherel commented judgmentally as she followed me into the kitchen, clearly referring to my daughter’s ass, which we could both see from here. Mandy was in the small dining room, standing next to a seated Kathy, who it took me a moment to realize was oddly slumped in a chair and on the computer screen in front of Kathy was a swirling image. That was quick, I told myself when I realized my daughter had hypnotized my niece. These damn psych grad students apparently used this tool like candy.
“Good subject,” Sherel said next as she put a hand out to bar me from leaving the kitchen. I was then interrogated by the dyke, who as usual was scantily dressed. It was becoming very clear to me now that I was expected to contribute in some other ways, not just semen. When Penny walked in to join us, I tried to not let her presence distract me. As before, I got a vibe of annoyance off both of them. Man haters!
“You drive here?” Sherel asked as she casually sat down, then pulled a distracted looking Penny into her lap. Both had only T-shirts and panties on, and when Sherel pushed Penny’s thighs apart a little, I got the message; look all you want but don’t touch. I swallowed nervously, as this gatekeeper could sink any hopes I had of getting more tail out of my daughter. Should I respect her for that? “Rented a car,” I replied in an upbeat tone.
“Hmm ... Andie’s car broke down yesterday,” Sherel said as she nuzzled Penny’s neck, getting little kisses now out of this gorgeous girl. Penny always seemed to avoid anyone’s eye contact and was now looking down at the floor as usual. It was like I wasn’t even here.
“Oh ... anything I can help with?” I asked sincerely.
“You’re leaving town—so no!”
“Well ... maybe ... I’ve been thinking on staying awhile,” I told her, which was a little true but not a solidified plan until this very moment. “Haven’t seen much of my daughter lately,” I added quickly.
“Until you started banging her that is.” Sherel said with smirk. Fucking dyke had me there, and so all I could think to do was raise my eyebrows a little in timid acknowledgement. “Kathy doesn’t have a car either,” Sherel stated as she licked Penny’s face a little.
“Ah,” I said with a guilty look, “ ... been thinking of getting Mandy one...”
“What kind?”
Shit, I warned myself. I’d walked right into that one. Thoughts of renting a local condo ran through my mind now, not for my daughter or Kathy, but for myself. I would fly home, drive my car back here, I was planning as I looked away from the two and thought more. “Did you have a model in mind?” my pathetic horny self asked.
“SUV...” Sherel replied without even blinking, “ ... one with a jump seat ... room for seven or eight.”
“Wow ... expensive,” I commented.
“So, your broke?”
“No ... no ... just retired ... can umm ... swing it maybe,” I admitted as Sherel had her pretty lap-bitch spread her thighs even more. “How ah ... often could I drop by—I mean I don’t want to be burden?” There it was; a pitiful sugar-daddy plea!
“For an SUV, I can schedule you ... if my name is on the lease!”
“Yeah,” I said softly, “ ... could I put—”
“No!” This terse response made me laugh nervously and to slowly climb to my feet. Fucking dyke owned my dick! This fact was accented by what Sherel did next, which was to lift up Penny’s T-shirt and then to pull the crotch of the girl’s panties to the side, exposing the worlds most beautiful pussy. “Trollip—get in here!” she called out as she blatantly rubbed Penny’s clit. I heard a distant, “Yes ma’am,” from my daughter, who didn’t even blink after walking into the kitchen to then squat down beside these two lesbians.
I looked nervously toward Kathy to confirm she was still in deep trance; she was! “Blow your dad while he thinks about vehicle financing,” Sherel commanded. I resisted a little at first as my daughter methodically worked to get my dick out but then gave in when she pouted up at me in the sexiest way. “Huh...” I hissed as she took my cock in her mouth and I almost lost it when Penny starting moaning herself.
“Tomorrow morning,” Sherel pressed as my daughter’s head started bobbing.
“Yeahhhh ... ahhhh ... yeahhh ... ah ... ah ... text me your info ... ahhhh ... fuck!”
“No pussy until I see it in the driveway!” Sherel snarled as I was expertly blown.
I promised her without hesitation!
“Hey, tell me what getting topped-off means!” my sister Beth demanded as she kneaded me in the ribs with her knees as I lay playing a video game on the couch. In the background, I could see a hovering Ina, one of Beth’s close friends. I thought, oh no, she was starting to catch on to things. Days had passed since we’d overheard my other sister getting banged by someone, who I more and more wondered if it might have actually been our dad. I mean, incest likely runs in families, right!
“I don’t know, look it up,” I complained as I rolled away as best I could.
“We did,” Beth whined.
“He’s lying—he knows!” Ina declared. “Yeah, well you two don’t want to know!” I retorted as I tried to go back to playing my game. The two then stepped away and began whispering to each other as I purposely turned up the volume on my game, so I didn’t have to listen to teenage-girl schemes. “Lily always laughs and shakes her head when ever I ask—won’t tell me!” Beth eventually complained.
“Fuck,” I growled as I paused my game and sat up to give them an annoyed look, “I’m not taking the blame for you not being told!”
“Please,” Beth begged, “Just tell us.”
“No! Lily will get mad at me ... she’ll tell you eventually ... she can’t keep secrets ... the little minx...” I knew Beth and Lily had called each other a lot in the last few days, and there was nothing I could do about it. Kathy too, I assumed, which always made me hard to think about. It was so fucking frustrating to try and get any progress report out of lesbians. Mind-fucking was going on, was all I could confirm.
“Come on...” Ina came up to beg, but I just ignored the two until the subject of butt-cracks came up. I chuckled with embarrassment as Ina admitted my little sister had told her the whole voyeur story. “One more crack at your crack gets an answer!” I laughed out. This quip earned me some pretty mean looks, which soon soften into what I thought might be some more scheming on their part.
“One second ... that’s it,” Beth announced as she gave her friend a firm nod as they both turned their butts toward me, “ ... but you got to promise to tell us everything!”
“Ah ... sure...” I said as I made a show of staring at two very sexy girls from the waist down. They flashed me ass! Hardly a second’s worth. Both had on sexy panties; Ina’s with a floral pattern that I very much admired. “Noo ... not enough ... I’ll tell you but you got to keep them down!” Fuck if they didn’t call my bluff!
“Tell us!” Beth demanded as I stared at two sets of naked butt-cheeks, both deserving of my full attention. I paused for several seconds before saying, “ ... it means she was getting ... well ... boned ... you know ... fucked!”
“What...” Beth whispered as I continued. “Someone ... unbeknownst to me,” I lied, “ ... was fucking our sister in the bathroom ... topping-off means he was going to ... you know ... finish ... inside her.” I had no idea why I was sugar coating this part; should have just been crude about it. Would have gotten a big laugh out of that later.
“Told you!” Ina exclaimed as she pulled her panties up, followed then by my sister.
