A minute later, Mari got what she wanted with a geyser that splattered the underside of her chin before she milked out the rest of my load all over her mountainous chest. I thanked my “Angel”, gave her another kiss, and she Left to go clean herself up.

That turned out to be the only time I came during the afternoon study group, although Alice did ask me to go down on her one more time. Only then did everyone remember that I hadn't gone down on Belle, to which she replied, “Not done with my period yet." Nobody bothered her any further. And in the end, everyone left, leaving me and Belle alone in the house.

No sooner did Mari's car disappear down the road than Belle Launched herself at me. She ended up sitting sideways in my lap, her arms wrapped around my neck while we made out on the couch. I reveled in the ability to let my hands roam all over her cute little body without fear of retribution or concern that I was crossing a line. For the entire study session, I'd been careful to be on my best behavior with Mari and especially Alice, and even Sam to an extent as I didn't want to accidentally give away how far we'd gone together. Over the past few weeks, Belle'’s petite body had become my personal playground. Now I could just let go and fondle my favorite little firecracker's ass, run my hands up her sides, and thumb her nipples - basically do whatever the hell I wanted to her.

“I wanna go down on you," I husked when we finally paused for air.

"I've been waiting all day to return the favor after you gave me a blowjob Last night and then left."

Belle giggled and tickled my nose with her fingertip. "You should never feel obligated to make it up to me. I gave you a blowjob because I wanted to.”

“And I want to go down on you because -I- want to go down on you. I was expecting you to take a turn when Alice asked. Why did you say you were still on your period?"

Belle sighed and brushed a few loose bangs of hair behind her ear.

“Well for one thing, I was worried about you doing something that would stretch me and make me tense up in pain. I really AM still sore down there. We can't have sex again yet."

I shook my head.

“I didn't ask for sex. I said wanted to go down on you. I don't even have to push any fingers inside, just lemme Lick your clit. Not much chance of stretching pussy muscles, right? An orgasm may even Loosen you up."

“And you would have this authoritative comprehension of female biology... how?"

“Just a theory," I grinned, “worthy of research, dontcha think?"

Belle laughed and nodded her agreement. It didn't take long to park her in my spot on the couch and take her jeans off. A minute later, she was gasping while holding her own Legs apart beneath the knees and letting her head fall back as my tongue went to work.

She did whimper a few times in what sounded like pain, causing me to pause and ask if I was hurting her. She said it wasn't bad, like sore calves after a long run, and grabbed the back of my head to shove me down into her crotch again. So I took that to mean she wanted me to keep going.

We didn't have to stop at one orgasm. This was the whole advantage of having a one-on-one; nobody was waiting, after all. When she squeaked cutely and dumped a load of honey into my mouth, I just grabbed onto her ass, dragged her a little closer to the edge of the couch, and ramped her up to another one. But after the second climax, she pushed my head away, gasping. And as I sat back on my heels with a smug grin of pride in my work, Belle groaned, “Okay, now it's starting to hurt again." Grimacing, she added, "The orgasms are nice but I feel every single clench down there."

My smug grin evaporated. I wiped my face with a couple of tissues and swiftly scooted next to her on the couch, hugging her tenderly.

“I'm sorry."

“I told you to stop apologizing." She looked back at me, her expression inviting a kiss, so I quickly bent to give her one. She sighed in contentment and pulled my arm a little tighter around her midsection.

“I feel bad though. You're hard as a rock - I can feel it against my butt -- and I know you want back inside, but I can't give that to you."

“It's alright. I came all over Mari's boobs a while ago. I'm good.”

Belle looked thoughtful. "I think you should call Sam."

I blinked. "Excuse me?"

“She wants to keep fucking you, doesn't she? That's more or less what I interrupted Last night, didn't I?"

“Uh, well... I mean, my mother was there,” I stammered before the full memory came back to me and I finished, "But yeah, she wanted to."
