"Hey Matt, my friend Carly is coming over ... and ... well ... I told her about how I like to bust your balls," Eliza said. "And she would like to try it too."
"What? Really? Carly?"
"Yeah, Carly. I know you think she's hot."
"Everyone thinks she's hot."
"Yeah, you lucked out."
"Is she really interested in me?"
"I told her you have a huge cock."
"I ... fuck." I mean, holy fuck. It can't be true. And yet, Carly showed up at our house a few minutes later. She was all dressed up, like she was about to go out for a night on the town. Her big breasts were on display in her low V-neck top, and those long legs ... damn. She's even hotter than I remembered.
"Hi Matt," she said with a pretty smile.
"Hi Carly, you look ... amazing."
"Thanks, Matt. I wanted to look nice for our first time."
"Come on, you two, let's get started," Eliza said, stepping between us. Just as well, because I had no idea what to say next. "We'll go up to my room." Eliza grabbed Carly's hand and dragged her along. I followed the two of them, my eyes riveted to Carly's ass. We walked into Eliza's room, and she turned to me. "Take off your clothes."
I looked at Carly, and suddenly embarrassment hit me. I didn't want to undress in front of her. Eliza stepped close to me, and she pulled my shirt off over my head. Then she undid the buttons on my shorts and pulled them down. My hard cock made a tent in my boxers. Eliza yanked them down too, exposing my erection. Carly stared at my cock, she looked hungry.
"So what should I do?" Carly asked.
"You'll start with some squeezing," Eliza said, and she stepped close to me. "Just grab his balls like this, and squeeze. Treat them like you own them."
"Fuck," I groaned as the pain hit me. That pain that Eliza had given me so many times before.
"Look how hard he is. His cock jumps every time I squeeze his nuts." Eliza demonstrated, kneading and squeezing my balls as my cock twitched.
"Let me try," Carly said as she moved in close. Eliza let go of my balls and Carly's hand shot between my legs. Her first touch was gentle, just feeling my balls. Her fingers roamed over them.
"Squeeze them, mash them flat in your grip," Eliza directed. Carly looked at me, then she pushed her fingers into the soft meat of my testicles. I winced in pain as she squished my balls flat. A low, desperate moan escaped my lips. It hurt so much, and yet it was so hot. My toes curled into the carpet, and my cock felt like granite.
"You can go harder, pinch one of them," Eliza suggested.
Carly's fingers shifted, then she pushed her thumb and first finger into my left ball. It felt like a lightning strike, a white-hot sensation of pain shooting through my mid-section.
"Fuck, Carly!" I groaned.
"Are you okay?" she asked as she let up.
"He's fine, keep going," Eliza said.
Carly repositioned my balls in the center of her palm, pulling the skin taut over the twin eggs. She looked up, meeting my eyes, and then she looked at Eliza, got a nod of encouragement, and her expression hardened. She jammed her fingers into my sensitive balls.
"FUCK!" I groaned as my legs started shaking and my knees gave out. I leaned into Carly, holding on to her to stay on my feet. My head landed on my shoulder. My whimpers of pain were just inches from her ear.
Her fingers eased up, and then something insane came over me. I needed more; I wanted Carly to fuck up my balls.
"Harder," I rasped, begging her for more.
She pushed her fingers deep into my balls, deforming them around her fingertips. I groaned as I slowly slid down her body onto my knees in front of her. She came down with me, holding my aching balls on the way down. She pushed me onto my back on the floor and sat between my legs, still gripping my balls as I lay on my back, gasping for breath like a fish out of water.
"Fuck, that was hot," Carly said, looking at me this time, not talking to my sister. She let go of my balls and grabbed the shaft of my cock. "And you're so fucking hard. You love this, don't you?"
I nodded yes as she leaned forward. I thought she was looking at my balls, but it was something much better. Her lips, soft and warm, wrapped around the head of my cock. I almost came right then, it was so good, so unexpected. Carly took me deep, her cheeks hollowing as she sucked me into her mouth. She didn't tease me. She just sucked my cock. Deeper and deeper, until I felt the tightness of her throat on the head. Her head bobbed, a steady, relentless rhythm, while her fingers fondled and kneaded my balls.
I was overwhelmed. My older sister watching, her lips parting, her eyes bright with voyeuristic hunger, while her hot friend sucked my cock.
"Carly, I'm going to ..." She didn't stop. If anything, she took me deeper, her nose pressing against my stomach. Her hand gave my balls one final sharp squeeze, and I suddenly erupted in her mouth. She swallowed it all as my cock spewed cum down her throat. Her fingers tugged on my sack as she drained all the cum from me, until I was a whimpering, boneless mess in front of her.
She pulled off my cock with a soft, satisfied pop, wiping her mouth with the back of her hand. I lay there in shock, having just had the most amazing orgasm of my life.
"I ... " Carly said quietly as she sat between my legs. "I need to ... I'm so horny. Can I?" She climbed up my body, and I reached for her hand and pulled her over to my face. She hiked up her skirt and pushed her panties aside, then she sat on my face. I leaned into her, licking and kissing her clit.
"Ohhh, yes," she moaned as I sucked on her clit. I started rhythmically licking her, my tongue focusing on her clit. She leaned back and reached for my balls, and she took them in her hand and squeezed them. Not hard enough to cause me pain, just on the edge of it. I moaned into her pussy and pushed on her clit with my tongue. "Ohhh fuck yes." Her moaning was getting louder, her pussy wetter. I ran my hands inside her shirt and up to those big breasts, I cupped them and pinched her nipples.
"Fuck!" she moaned. "OH FUCK!" Her pussy covered my face in her juices as she cried out. Her legs clamped around my head as she got off. She rocked back and forth on my face as she finished her orgasm. When she climbed off me, she looked every bit as spent as I had before.
I glanced over to see my sister watching, her face flushed and her hand on her pussy. Was she jilling herself while I did her friend? It sure looked like it.
She and Carly eventually gathered themselves and left the room. I heard them talking, then Carly left the house. Eliza came up to my room and stuck her head in the door.
"I have to admit, I wish you could eat my pussy."
"Any time you want."
"Fuck," she mumbled and walked away.
Fuck.
