I was sitting on the couch playing on my tablet when my younger sister entered the living room, took a seat in the recliner, and huffed.
“What’s up, Beth? How was your date last night?” I said.
“It was a bust, Greg. I don’t think he will ask me out again.”
“Why not?”
“Because I wouldn’t do what he asked. He said he wasn’t interested in dating an ice princess.”
I put my tablet down. Beth wore her usual garb, sweatpants, and an oversized shirt. My sister was curvy and a little overweight, like our mother.
“So, what did your boyfriend want you to do?”
“He asked me to give him a blowjob. When I said I wouldn’t, he said girls like me have to if they want guys to ask them out. He got pissed and took me home.”
“What did he mean by girls like you?”
“You know. Big girls.”
“There’s nothing wrong with how you look, Beth. Can I ask you something personal?”
Beth nodded.
“Don’t you like sex? What do you have against giving a guy a blowjob?”
“I don’t know if I like sex. I’ve never done it. I’m not against it, but I don’t know how. I’ve only kissed and let a boy feel my tits.”
“Do you like it when a guy feels you up?” Beth nodded. “I’ll let you in on a secret. When a guy goes out with a girl, and she lets him feel her up, he gets excited and goes home frustrated if the girl doesn’t do anything for him. You know what they say—turn about is fair play. If a guy has to take care of himself, he’ll probably find another girl.”
“How do I learn?”
“It isn’t rocket science.” I wiggled my eyebrows. “If you want to practice, let me know.”
I prepared for Beth’s wrath, but she said, “Really?”
To say I was shocked was an understatement. Then I decided to see if my sister was serious.
“I was kidding.”
“Oh. I thought you’d help me.”
“Really?” Beth nodded. “I guess so if you’re serious.”
“What do you want me to do?”
I decided to go for broke. “Show me your tits.”
While waiting for my sister to say something, she stood, grabbed her shirt, and pulled it off. I couldn’t believe Beth was standing before me in her bra. She giggled and released her bra, letting it drop to the floor.
“Nice tits.”
“Thanks. I have a big ass and small boobs.”
I picked up her bra and checked the tag. “Thirty-eight C. They’re not small. Can I touch them?”
Beth nodded, so I covered her tits with my hands, massaging them. As I played with my sister’s tits, she reached for my shorts and unfastened them.
“I want to see your penis.”
Laughing, I helped Beth push my shorts and underwear down my legs. “A word of advice, guys refer to them as cocks or dicks.”
Beth wrapped her fingers around my cock, and said, “I guess it’s why they call girls cocksuckers. What do I do now?”
“Take off your pants and kneel on the floor.”
Beth giggled as she removed her sweatpants and panties, turned around, let me see her, then knelt on the floor. I moved closer and told my sister to kiss my cock. Holding my dick, she kissed the head, then licked it.
“Are all cocks this big?”
“My cock is about seven and a half inches. Put it into your mouth and bob your head while you suck. Watch your teeth.”
Beth took my cock into her mouth, clamped her lips around the shaft, and moved her head. I’d had a few blowjobs, but my sister was as good as anyone. She seemed to get into it and moaned. I told Beth to play with my nuts, so she did.
“Try to take more.”
Beth moved her head forward, swallowing half my cock.
“Are you sure this is your first time?”
Beth nodded. “Am I doing it right?”
“You’re doing great.”
Beth returned her mouth to my cock and gagged but continued trying to deep throat my cock. I put my hands on her head and guided her head.
“I’m coming.”
As the first spurt of cum shot into her mouth, I heard, “What’s going on?”
My sister pulled her head back as my semen hit her face. We saw our mother in the doorway as Beth tried to cover herself. I thought we were in real trouble until Mom laughed.
Beth hung her head, took a deep breath, and explained she wanted to learn how to perform oral sex and asked me.
Mom stepped closer. “So, no one was forced?”
Beth and I shook our heads.
“Do you like sucking cock, Beth?” Mom said.
“Yeah, but I gag.”
“It takes practice with a cock as large as Greg’s.” Mom used a finger to gather my semen from my sister’s face and popped it into her mouth. “Mmmm, tasty. Did you like it?”
Beth nodded.
I felt weird standing in front of my mom butt-naked.
“Would you like a few pointers?” Mom asked.
My sister nodded. I gasped as Mom stripped, knelt next to Beth, and took my cock into her mouth. A moment later, I was erect, and Mom took me into her throat.
“Who taught you, Mom?” Beth asked.
“Your grandparents. Girls like us have to be good cocksuckers. I asked Grandma what I should do to get dates. She taught me how to suck my Dad’s cock.”
Mom and Beth shared my cock for the next few minutes. Mom helped my sister learn to relax and take it all. When I came, Beth swallowed everything.
“What else do girls like us need to know, Mom?”
“I’ll show you as soon as we get your brother’s cock hard again. Girls like us need to know how to fuck too.”
