[MFf] me [bi] and my fiance [str8] fuck my sister and take her virginity [bi] [inc]

One late night I had set the mood for myself – candles, music, a little lesbian porn – everything to get a girl like me riled up. I undressed and slowly teased myself till I was soaking wet. Ready for something bigger, I got out a vibrator and started fucking myself with it as the porn played more loudly than I realized in the background. Getting lost in the trance, I must’ve started to moan so loud my dog heard and pawed at my door. I figured I won’t be much long, she’ll be ok for just a little bit more. I felt myself edging again, gaining closure to climax…

then BAM!

My door flew open and my sister walks in – porn still on, me naked with a vibrator in me.

“Oh! I -”

“Close the door!”

My sister clammers to close it as I cover myself up. She stands quiet in the corner for a moment.

“I didn’t rea-”

“It’s ok…” I pause the porn and sit up. “You’re not uncomfortable with that, are you?”

“I mean, I’ve seen you naked before… but not like this.”

I giggle a little. “Like this how?”
