My twin sister and I became closer than ever (PART 18)

I'm M20 and she's F20, reminder: Lisa was eating out my sister and she told me to fuck Lisa from behind, but Lisa noticed and screamed at my bare cock cms away from her

It took 30mn for my sister to convince Lisa that incest isn't "that bad". Lisa was horrified by me and how comfy we seemed to be while being naked. She couldn't process it and honestly she gave a valid reaction. She stayed behind my sister, she didn't want me to see her like I was a monster (realized she's a lesb so that's fair ig). She kept trying to dress back and leave our home repeating we're freaks but after lots of chats and me just standing like a complete idiot ... Lisa agreed for a threesome under the condition that I don't penetrate her kitty ... which my sister sighed because she wanted me to learn how to fuck a girl before my gf comes over.

It was awkward, my cock got super tiny small from all the shame. My sister glanced at me and said "let's get his mood back up". Lisa nervously replied "I thought we were also posing for nudes. "I just wanna have good sex rn"

And they started lesbian kissing each other playing with their tits, moaning. Turned me rock hard and I got closer, touching myself. After my sister noticed me, they both got on their knees near me and my sister started blowing me with her cute eyes staring into my soul. Lisa was grossed out. Then both blowed me at the same time and I came on their lips and their foreheads

Sis got up and made out with me while Lisa was playing with my balls and my sister's pussy. I was the luckiest brother ever as I rubbed on my sister's thighs and came near her pussy.

It was so long and passionate: they fucked each other with strap ons, I got to use weird toys on them + other things. They took their nude pics without me, then we all got to my bed, each girl on my arm. Lisa slept first, and I fingered my sis until we fell asleep. Before I was asleep, my brain asked myself a big question: WTF are U doing you incestual MF
