My gf has me pleasure her little sister at a party [MF]

Okay this actually just happened last night and I had to write it down.

The cast:

Me (Mark): I’m average height, slight dad bod but not overweight. Short brown hair and a beard. 7” and thick cock that impresses most women. I’m 23.

My gf (Hannah): taller than me, blonde, body to die for. She looks a lot like this: https://i.imgur.com/ZPbi8Vl.jpg
23 and we’ve been dating for a year.

Gfs sister (Kendall): adopted and looks very different from Hannah. She is shorter, brunette, olive skin. Thicker than her sister but in a good way. Her face is cuteish but kinda homely. Like she could probably be really sexy if she knew what to do with herself. Always been pretty awkward. 18 and a senior in high school. Her body kinda looks like this: https://i.imgur.com/PtiXmfe.jpg

Some back ground info: Hannah and I go to college in her hometown. We have an apartment and Kendall lives at home. And this is important, I’m really good at cunnilingus.

So last night Hannah’s parents are out of town, so she convinced Kendall she should throw a holiday party for her senior class to try and get some clout. She has a few friends but definitely not throw a huge party level of friends. But Hannah hooks up with this guy some time (were open) who’s younger sister is really popular and in the same school. So she convinced him to have her go and invite a lot of people.

I know, it’s very high school movie or Disney channel. Hannah says I have to go. I felt a little weird about going to a high school party but she said Derek (the guy) and probably some of his friends would be there too, and having a bunch of college kids would make Kendall seem cooler, so I obliged.

Hannah gave Kendall a makeover and she honestly looked really good. Her outfit showed off her impressive curves. She was wearing tight jeans and a crop top.

The party had a pretty good turn out. It was mostly girls. I would’ve killed for a party that looked like this when I was in high school. Hannah was disappointed about the ratio. It turns out, what she really wanted for the party was for Kendall to get laid before she went off to college. But there more girls here, and most of them were more confident. It doesn’t take much to get high schoolers drunk, so before long most of the guys have already snuck off to some corner of their huge house with a girl, or guy. The pickings were slim, and both Hannah and Kendall were pretty bummed.

I was bummed too, because I knew Hannah would be fucking Derek tonight to repay him for getting his sister to invite everyone. His sister actually hit on me a little, but that felt like a really bad idea.

What was a much worse idea, is what Hannah pulled me aside to request before she went upstairs with Derek.

“I was really hoping Kendall could get laid at this party.”

“Yeah that’s too bad. Bad luck. Happens to the best of us.”

“This will crush her confidence. The girl really needs to just get off.”

“You could ask Derek to!” I said half jokingly, thinking I could get Hannah to myself.

“No, he’s honestly kinda a creep. This is the last time he’s getting any of this. I just wish there was someone I trusted…” and then she just stared at me…

“No way.” I said. She started to pout. I couldn’t believe she was serious.

“No hannah, I’m not gonna fuck your little sister!”

“Don’t fuck her! Just…you know…” and then she flicked her tongue around.

“How is that better?”

She smiled at me. I love her smile. “I’ve told her about how good you are at it. And she’s never had an orgasm. I’m sure you could make her feel better about tonight.”

I looked over at Kendall. She was sitting on a couch looking bored and sad. And sexy. Her tits poured out of her small top.

I looked back at Hannah. “Please?”

Of course I gave in. Hannah kissed me and took Derek upstairs. She told me absolutely nothing other than making out and me eating her out was allowed to happen. Fine by me.

I went and sat next to Kendall.

“Nice party.”

“Heh. Yeah, sure.” She leaned back. Her tits…

I don’t know what possessed me. I don’t know if she and her sister had discussed this. It might’ve been a real risk but I just, leaned forward and started kissing her neck. She tensed up in shock but didn’t stop me.

“Mark…what…mm…”

I kept kissing and licking, and started rubbing her thick leg.

“Mark…Hannah…”

“Hannah’s fine with it. I asked her if I could.” I lied for the sake of her confidence. It seemed to be enough for her. She spread her legs and started playing with my hair.

“We should go to your room.” She shook her head and jumped up. She took my hand and led me. Her door was cracked so we walked in…to one of Derek’s friends absolutely railing her from behind. I’m guessing that’s gonna be a thing.

So Kendall took my to the next door over, the laundry room. I grabbed her and pushed her against the dryer and started kissing her, grabbing her luscious body, eventually peeling her top off. Her tits were the most gorgoeus I’ve ever seen. But I knew my objective. And Kendall reminded me of it.

“I hear you’re really good…at…”

It’s all she had to say. I ripped her pants off and was delighted to see she was going commando. “Wow. Hannah is really slutting you up, huh?” She blushed and leaned back.

He pussy was shaved, soft, and smooth. I dove in. I did my expert work. Teasing her clit, parting her lips, spelling the alphabet, the whole nine yards. This went on for a very long time. But eventually, my work paid off. She tended and shuttered, and let out some very breathy moans. She grabbed my hair and pulled as she came hard. She pushed me away and laid back against the wall, panting. Her pussy was glistening. I stood there for a bit, just kissing her inner thigh occasionally. Then she sat up, slid to the floor and got on her knees in front of me.

I wanted to stop her. Except you know, I didn’t. I thought, how could I stop her without giving away that Hannah asked me to just eat her out? I mean, I could’ve easily, but this was the justification I gave myself for what came next.

She pulled my jeans and boxers down and actually gasped when my cock came out. I wondered if she’d ever even seen a picture of one.

To her credit she wasted no time. She didn’t even touch it, just put her mouth right on it and started sucking. Like, sucking as if from a straw. It felt weirdly good but, I couldn’t let this poor naive girl go to college thinking this was a blow job. “Open your mouth,” I told her, and she obeyed. I slide my cock ina few inches. “Now close it…no teeth though, just your lips.”

I was a little awkward. I didn’t want to brutally face fuck my gfs naive young sister, so I slid my cock in and out for a little bit, very slowly, slowly giving her more of it. She had good instincts. She started moving her tongue on it, and eventually took over, bobbing her head up and down. I told her to grab it and move her hand with her mouth. At that point, she was giving me a really good blow job. The whole situation was hot enough, I told her I was going to cum and she should stop. She didn’t stop.

She swallowed every last drop as I exploded into her mouth. She was a good girl for me, even slurping up some that spilled out. When I pulled my cock out, she opened her mouth for me to show me she had swallowed. What a little minx.

I leaned down and kissed her, then helped her up. “Don’t tell Hannah but that was a great blowjob, better than hers.” She blushed. “Really?”

No, Hannah gives the best blowjobs in the world, but I wasn’t gonna tell Kendall that. I smacked her big ass and told her to get dressed. I walked her back to her room which was now empty and said goodnight.

I figured Hannah was in her old room so i headed there. I came in to catch the end of her session with Derek. He was eating her ass and Hannah winked at me as I sat down to watch. She came, or pretended to, then told Derek to cum on her tits. He did so pretty quickly, smiled at me and left. I grabbed a towel and helped clean her up. She went to kiss me but I stopped her. “You might not want to taste your sister…” she giggled and gave me a huge hug. “Thank you so much!”

I don’t know how I managed to get an incredible blowjob and feel like a hero, but it turned out to be a great night. I told Hannah about the BJ and she wasn’t mad. She just made me eat her out, which I had no complaints about!!
