Cuming from my ass

Feeling my half-erect cock, Sumi breaks the kiss.

"Oh wow Johnny. Already? You're much more energetic than your dad... Now, I can't let you go like that, right? Isn't it painful to have your balls full and needing to cum again?" She asks, a bit innocently.

"What?... yes.. Yes! Of course mommy, very painful." I say, still dreaming for more action with her.

As if satisfied with my answer, Sumi smiles. "Right. Let mommy help. But... " The next part is quieter, as she is mumbling to herself (or so I think), but I can still hear it easily. "...your dad told me it's sometime painful after the first one... Oh! I know!" she finishes her sentence, energetically.

Looking back at me, Sumi says, full of enthusiasms "I know a way to make you cum. You'll love it! No pain or discomfort!" Sumi is soo beautiful when she's this happy, I'm ready let her try whatever, though I should have expected what she said next... "Remember yesterday? Flip around, let me see your ass Johnny!"

I'm a bit baffled, but I'd do anything if it helps me get in her panties before my dad comes back from vacation. I was dreaming of getting closer to her and she's making the first moves, no way I'm pushing her away.

I flip on my front, exposing my ass to her. Sumi gently caresses my ass cheeks. It feels good to be honest. To my surprise, I can feel her face on my ass, as she kisses my ass cheeks. As I'm left wondering what is she doing, she kiss her way between my cheeks and start eating my ass, running her tongue all over my anus, making me release small moans.

"That's it, let it out. Moan for me, Johnny."

Sumi goes back to eating my ass, making me moan again. After a few minutes, she stops eating my ass, but it doesn't take long that I can feel her fingers caressing it instead. I don't where that came from, but somehow Sumi had lube with her, as I can feel her slippery, lubed up fingers tracing my anus before sliding right in. Same as yesterday, Sumi starts massaging my prostate with her fingers, probing it and pushing against it.

"Good boy. Moan for mommy. Let it out. Cum for me. Cum from your ass for mommy. Doesn't mater what's happening here, or if it feels wrong, or weird. You're enjoying it and that's all that matters. Focus on the sensations and pleasure."

Under her fingering and care, I end up cuming all over my bedsheets, covering them in cum under me as I squirm and moan. Her fingers still inside me, Sumi lay down on top of me. She kisses my ear and whispers "Good boy. Mommy's proud of you. I think soon, we'll be able to go to the next step of our relationship."
