"Let me get this straight.. you want me to fuck your sister?"

You smiled at me.

"No, hun. I want you to let my sister fuck you!" you said, squeezing my thigh comfortingly. "You know how long it's been since she's had a boyfriend, and she gets so wound up! You know how long she's had a crush on you.."

"But.. won't that hurt?" I asked, cheeks flushing red at the mere thought. Your sister was infamously hung. Part of the reason she hadn't had a boyfriend for so long was that her cock was the size of her forearm and everybody knew she was the kinkiest futa within 50 miles.

"Not if you relax.. she'll use plenty of lube. My sis knows how to treat a boy right!" you chirped. It was almost unbelivable that you were asking me to bend and spread for your little sister based on your tone. "I know it's kinda scary.. but believe me, she'll play your prostate like a fiddle!"

Ever since she'd turned 18, she'd been unbeliveably horny. She'd grope my ass as she passed in the kitchen, make suggestive comments at any opportunity. Somehow, you always played it off as if it was the most innocent thing in the world. "Oh, she's just playing, babe. You do show a lot of skin. Can you blame her for being horny?"

Because I love you, I agreed. Before I knew exactly what was happening, you'd dressed me in your skimpiest lingerie, the stuff you bought for our first anniversary, my cock bulging in the lace panties as you beckoned me towards your sister's bedroom. Before I could say another word, I was inside, in the dim bedroom lit only by candlelight. She sat on the bed, smirking, flanked all around by dildos, vibrators, butt plugs, whips, crops, canes and floggers.

"Hey, Sweetie.. you ready for a night you'll never forget?" she purred.

From that night on, thursday was our date night. You went out with the girls, while I entertained your sister. I can't believe how quickly I stained your panties with cum.. Honestly, I wear them more than you do at this point..

You were right, she really does know how to treat a boy. I don't know if I've ever cum so hard.. The three of us share an apartment now. To be honest, we all share the same bed.. what used to be her bedroom is a sort of.. playroom now. In her words "somewhere where your slutty little clitty won't make a mess when I pummel your prostate".

It really didn't take me that long to get used to it..

Hi there! I'm looking for someone to play my very supportive girlfriend's extremely horny, kinky futa little sister who's always had a crush for me. It's date night, and my boipussy is about to get destroyed.
