Accidently starting a poly relationship with me [22F], my sister [18F], and my fiancé [22M] [FFM]

The night of my sister’s 18th birthday, she came to me.

“So I have a request: I don’t want to be a virgin when I see my boyfriend in 5 months… Could your fiancé maybe take my virginity?”

She always had the hots for him – but she’d never admit that.

But come her 18th birthday, I agreed – under the condition that he had to do what I say, nothing more, nothing less.

So at midnight she came into my room in corset I quickly stripped off her. I had my fiancé stroke himself to us kissing and sucking on each other’s bodies till he was rock hard. I brought my sister down to his cock and showed her how to stroke and suck a dick right… And she took over, learning quickly what turned him on. I had to pull her off of him, she was so addicted.

“How about we pop that cherry?” I say, laying her down. My fiancé slowly penetrated her, spreading her pussy as wide as it’s ever been. She shivered as his cock slid all the way into her cervix… And then he began to fuck her. I told him how fast, how hard, and how to kiss her… Making her cum three times during her very first experience… Then it was my fiancé’s turn to finish.

“I want it all over me” My sister said. “I wanna be a naughty girl!”

I smirked, having different plans.

My fiancé continued to fuck her in doggy, his cock trembling in her. I could see his eyes roll back as he barebacked the tightest pussy he’s ever had. I could see him about to finish! I jumped up and right as he was about to pull out, I grabbed his ass and shoved him deep into her. His cock exploded with cum in her fertile pussy. She came again just from the sensation of being filled and my fiancé pounded her to a second orgasm himself till both were exhausted.

“I can’t believe he finished in me… I wanted it on my face!” She said, frustrated and a little nervous.

“I said I could say what he does, not you. I hope you learned your lesson.” I giggle as I kick her out of my room.

But she remained very, VERY interested in my fiancé.

She’d invite him over just to fuck him over and over again – bareback, no condom. Apparently I got her addicted to breeding fresh outta high school.

She just moved in with us last month, and my God do we breed like rabbits since we all work from home!

And it makes me so incredibly jealous. ;)
