My twin sister and I became closer than ever (PART 14)

I'm M20 and she's F20, reminder: This shaving shower thing was becoming a circus atp. With soap on top of my dick, she wanted me to clean her up inside

It was all so creamy, and so soft and so easy to sneak my dick inside her with all that soap. I had no idea who I became, maybe a never ending nightmare, this is my sister dammit!

But lust took over me. I rubbed myself so hard inside her butt cheeks making sure I don't touch her pussy like she told me. The soap transformed itself into thousand of bubbles and at some point it was just me and my dick inside a thick cloud.
My sister had her arms on the wall for support, and her knees were almost touching the bathtub. I realized this is my first sexual experience ever, and it's with my sister. She was starting to moan slightly, her nipples were like super straight forward. Minutes later, it was crazy impossible to hold my cum. My sister noticed it, turned around as her ass cheeks clapped while she turned, and she put my whole cock in her mouth.

"We don't wanna dirty ourselves anymore, do we? Now shoot"

I executed her majesty's orders and came everything into her throat. She got up like nothing happened, put a towel on her and started to get out. Before she got out of the bathroom, she told me, "You never had sex, right?"

I shook my head, and she said, "If you wanna make your girlfriend happy, we have to practice this too now"

That shocked me, but internally I was happy, I did say, "Are you OUT of your MIND?"

She rolled her eyes, "Well I'm having sex tonight with a girl I'm bringing over. Don't disturb us."

That's not the first time she's doing the "bringing a girl" thing, but the way she said it now means she wants me to disturb them.

I'm sorry for the updates getting long to get published. For anyone still doubting, this is a real life story, that happened to me weeks ago. Idk how else I can prove to you guys, Ik there's many fakes around here, just gotta believe my words
