“Mmm,” Christy said before she returned her attention to her favorite flavors.
“God, that’s sexy,” Erin said, her voice scarcely a whisper.
Christy bobbed gently and then swallowed about half my length. She paused for a couple of deep breaths before she slowly forced my cock into her throat. Her lips closed around the base, and I had to grip the edge of the pool to steady myself.
“I can’t wait,” Erin whispered, “big brother.”
Christy fucked me with her mouth, and I struggled not to blow my load then and there.
Erin laughed, kissed my ear again, and sat back. Then she said in a louder voice, “All done. Can you see anything?” I groaned something inarticulate, and she laughed. “I’ll take that as a no.”
Christy pulled back, and her lips caressed the entire length of my shaft. I groaned again and felt lightheaded.
“Now that’s incredible,” Leah said from above me. “Wish I could do it.”
“It’s easy,” Christy said as she caught her breath. “Well, not really, but I could show you.”
“I’ve tried,” Leah said. “I can’t do it, I’m afraid.”
“If at first you don’t suck seed,” I said, but Christy was the only one who heard the pun.
“Suck, suck again. Mmm, yes, please.”
Leah touched my shoulders and spoke quietly in my ear, “Is it still incest if they’re sisters-in-law?”
“I don’t think so…”
“…but you’re willing to try?” she finished with a wry, breathy chuckle. “You’re so much like her. And I hope you don’t mind our little subterfuge. With the blindfolds,” she added, in case I hadn’t made the connection.
I had. Mark was fine with Erin and me, and Brooke had fantasies about her own brother, but Wren and Trip were taboo kryptonite. Leah had thoughtfully provided a distraction so Erin and I could talk.
They learned from the best, I thought with a silent laugh.
“She wanted to tell you herself,” Leah added. “She loves you, you know.”
“Yeah, I know. And I love her, even when she drives me crazy.”
“That’s what sisters’re for!” Leah laughed. Then she kissed my cheek and straightened. She said in a normal voice, “C’mon, Er, let’s hand out the chips. I’m ready for a dick.”
“Totally!”
“Ladies…?” Leah prompted. She shook the bag and rattled the plastic poker chips. “Come and get ’em.”
“Unh,” Christy complained. “Do we have to stop?”
“Come on,” Wren told her. “You have the rest of your life, remember?”
“Not you too!”
“Hey, I’m the one who started this whole thing, remember?”
“How can I forget, Miss Matchmaker?”
“Come on,” Wren said again, this time from the top of the stairs, “hop out. The sooner we get these chips, the sooner you can get back to sucking.”
Water swirled around my leg as Christy moved around it. She vaulted smoothly to the side, and droplets spattered the concrete deck as she joined the group a few feet away.
“Paul is red, Trip is white, Mark is blue,” Leah said. “Are we ready? Erin, you first.”
The chips clinked softly.
“Oh my God! Seriously?”
“It’s a sign!” Christy said.
“Don’t be disgusting,” Wren told her. “Draw again, Erin.”
“Of course. That goes without saying.”
“Oh my gosh, that’s exactly what— Never mind. Here, I’ll take it,” Christy said. “Thank you. Feel free to draw another.”
“Thanks,” Erin chuckled dryly, “I think I will.”
“No,” Brooke explained, “she meant, ‘feel free to draw another red one.’”
“What about the rest of us?” Leah teased. “Don’t we get a turn with him?”
“Only if I can watch!” Christy said.
“That’s the spirit,” Erin laughed. The poker chips rattled faintly. “Okay, that works. Next?”
She and the others joked and made suggestive comments as they drew their chips.
“Are we ready?” Leah said at last. “Come on, let’s do this. Hey, Paul, can we borrow your watch?”
“Sure.” I unsnapped the bracelet and held it up.
She took it from me and then laughed. “How d’you tell time on this thing?”
“I know, right?” Christy said. “There’s, like, a million numbers.”
“A million?” Brooke teased. “A thousand thousand? Ten to the sixth?”
“Smarty-pants.”
“It’s just a watch,” Erin said. “Here, I’ll do it. Who wants to go first?”
“Me!” “I do!” “Yes, please.”
They huddled and began discussing it in low voices.
“Okay, we’re ready,” Erin said. “Ladies… into the pool and assume the position. Remember, guys, no hands. Only dicks.”
“Fine by me,” Mark joked.
Two women walked down the steps, while Christy and someone larger—Wren?—simply hopped into the water beside me. They waded away, and I felt a different woman move between my legs. She’d come from the direction of the stairs.
“Here we go,” Mark said, “what we’ve all been waiting for.”
“Mmm,” the woman in front of me agreed.
I thought I knew who she was, but a single word wasn’t enough to confirm it.
“No talking,” Wren warned from the stairs. “Only touching.”
“And sucking!” Christy said, also from my left.
“I’m serious,” Wren told her. “We don’t want to give the guys any hints.”
“Fine, Miss Sea Lawyer.”
“Hold on,” Brooke said, from somewhere closer, “we can’t both—”
“No talking!” Wren snapped.
“She’s right,” Erin said in a gentler tone, definitely from the stairs.
“Sorry, guys,” Wren said, “we’ll figure it out.”
“Never let a woman pick teams,” Trip joked.
“Hey, watch it,” she warned.
“Sorry, babe. Just kidding.”
“Uh-huh.”
“Are we ready?” Erin prompted. “You don’t have to say anything, ladies! Just nod or wave.”
The woman in front of me waved, returned her hand to my thigh, and then rubbed them both in anticipation.
“Me too,” I said, and she rewarded me with a soft laugh.
“All right,” Erin said. “On your marks… get set… suck!”
Warm lips closed around my dick, which had softened a bit during the pre-game confusion. It swelled immediately, and the woman moaned in surprise. Then she began sucking in earnest. I already thought I knew who she was, and her style confirmed it. I knew her better than anyone except Christy, so I stopped thinking and simply enjoyed myself instead.
“Time!” Erin called, long before I was ready. “I mean it,” she laughed. “Stop!”
“Oh, brother,” Wren said.
“No talking, remember?” Erin said to her. “Time! Seriously,” she said to someone else. “Stop sucking.”
“Unh,” Christy complained. She’d been sucking Mark, although I didn’t think he’d recognize her voice.
“Okay, guys,” Erin said. “Time to guess. Paul, you first.”
“Leah,” I said confidently.
“He’s good,” Leah said, and pressed a poker chip into my hand. Then she gave my dick a farewell kiss. “Mmm, I’ve missed this, but I’ll be back.”
“We’re looking forward to it,” I said.
“We? Oh, that’s right! See you soon, Mr. Big.”
“Mark, your turn,” Erin said. “Who was it?”
“I’m not sure. Brooke, maybe? Although… No, I’m gonna stick with Brooke.”
“Oh, sorry,” Erin said insincerely. “The lady keeps her chip. Trip? What about you?”
“Wren,” he said, as confident as I’d been.
“Seriously?” Wren said. “I thought you knew me better than that.”
“Um… babe… I’m wearing a blindfold.”
“Still, you—”
“Be nice,” Christy told her.
Wren huffed. “Fine, whatever.”
