My twin sister and I became closer than ever (PART 20)

'm M20 and she's F20, reminder: After that threesome, things slowly went back to normal. At least that's what I thought

The days after weren't that interesting. She wasn't that crazy-horny as she was, she went back wearing actual boring clothes, and on my side, I also experienced a decline in my own sex arousal: I would still occasionally get hard peeking at my sister's nudes (that I shared from her pc to mine) but I didn't have those crazy urges anymore. I spent my days getting my health back and speaking with my actual gf on the phone for hours played a big nice role.

I still remembered when my sister said she'd be open to have me fucking her, and I'm kinda happy she forgot about it. I tried to leave everything bad behind me and pretended I've never gone intimate with my twin sis.

That was until a Saturday where she asked me to netflix and chill with her. She was wearing for some womenish reason a super small tight bra and shorts. Instead of sitting next to me, she rested her head on my lap, specifically my crotch part. During the whole time, I couldn't look away at those tits hanging and from my pov I was seeing them nude.

She slowly drifted to sleep and I realized fuck it, she's testing me and I can't resist. And so I got hard on her sleeping face, it was directly on her mouth. Then I had the horrible idea to take my cock out my pants cause I was hurting myself with my boner; and that boner humiliated me by slapping itself on my sister's face. It started to rub on her cheeks, then her nose, near her eyes, I tried to masturbate out of her way but her face was like a big target. And the worst part? I started to ejaculate everywhere on that pretty face, her nose, her cheeks, her lips ... only to realize she was fake-sleeping when she opened her eyes and saw my cock inside her mouth

"Who's being an incest mf now?" she ironically told me as I'm always trying to bring up the morality of our actions ...
