Chapter 1282: 1282

I latched on like a starving infant, suckling away to my heart's content while grabbing all the tit flesh I could with both hands.

"Mmm... Matty..." Mari moaned, her eyelids fluttering while cradling my head to her bosom. She watched me nursing, a serene smile on her face. A minute later, her fingers wrapped around my dick once again, and she jacked her hand up and down along its length with complete disregard for what might eventually happen if she kept it up.

Or perhaps she knew exactly what would happen. In fact, she seemed determined to make it happen. And whatever her motivations, Mari indeed made it happen. I was still suckling away at her beautiful breasts, having switched to the other nipple by now, when I felt the tell-tale tingling in my balls. I tried to fight the urge, tried to make this moment last a lifetime, but I couldn't hold it forever and she wasn't about to stop stroking. So I finally pulled my mouth off her teat and gasped, "Mari! Mari! Ohmigawd, Angel... You're gonna make me cum!"

If my intent was to make her stop stroking me, I failed miserably. Mari heard my words, moaned excitedly, and started jacking me even faster, rapidly spurring me on to the point of no return.

"Mari!" I pleaded again. "Mari... Oh... Angel... I... I... UNNNGGGHHH!!"

My hands squeezed down on Mari's massive mammaries, my butt bucked up off Belle's bed, and my cock started squirting creamy cum all over my own belly.

"Ay, Dios mio!" Mari exclaimed at the sight of it. But she didn't stop stroking.

"Ungggh! Ungggh! Ungggh!"

Over and over I came, shooting at least six shots of sperm across my stomach. The remaining globs lost power and just sort of trickled out, but Mari kept pumping until there was nothing left. A lot of the white globules stuck to her skin, and on impulse she raised her hand to her nose to take a sniff. For a second there, I thought she was going to take a lick. But instead she stretched out her arm, holding her hand up for our audience to have a better look. "Can you believe I just did that?" she asked, elated with her own boldness.

Belle sat in her desk chair, an unreadable expression on her face. "No," she replied in a quiet voice. "I really can't."

Mari frowned at her best friend's flat tone. I was a little too wiped out (and blissfully happy from the orgasm) to really notice. But I noticed when Belle clenched her jaw, got out of the chair, and left the room.

Mari and I looked at each other, both of us unsure what to do. Mari spurred herself into action before me, sliding off the bed, grabbing a wad of tissues to blot up the spunk covering her hand, and marched out the door ignoring her toplessness. She must've gone to the bathroom to wash her hands, because she came back a minute later, grabbed her bra and sweater, and gave me a quick peck on the lips.

"You know you're gonna have to get over this whole brother-sister thing, right?" she intoned seriously, more of a statement than a question.

I sighed, not sure how to answer her.

With a shrug, she got off the bed and started heading for the open doorway, intent on finding her best friend. But just before she went through, she paused and glanced back at me. "Did you call me 'Angel' just before you came?"

I frowned and searched through my memory, not quite sure myself, but I thought I might have.

She giggled. "I kinda liked it." And then she left.

Halloween -

****

I didn't really get over the brother-sister thing. Mari and Belle had their little girl chat, and after Mari went home, Belle and I sat down and had our own talk. But it was the same conversation we'd already had before, with me thinking of her as my little sister and her thinking of me as her hunky unrelated step-brother. Her dad came home early and we were behind on making dinner, so we never actually finished the conversation. And after dinner I went back to my own house.

Word of Mari's boldness traveled fast.

Alice was waiting for me and Belle at the parking lot and came over to us as soon as we stepped onto the curb. Literally, the first words out of her mouth were, "Is it true Mari let you suck on her boobs while giving you a hand job until you came on your belly?"

I blinked twice and looked around to make sure nobody else was nearby. Other people were walking in from the parking lot, so I quickly grabbed Alice by the elbow and pulled her toward a quiet corner where I could at least have my back to a wall and see if anyone was eavesdropping, and Belle followed. "Can we not have these conversations out in public?" I hissed.

Belle drawled, "Did you wanna do it next or something?"

"What? Eww!" Alice made a stink face. "I just wanted confirmation because doing that is the LAST thing I ever thought Mari would do."

"Well, not the LAST thing," Belle snarked.

Alice rolled her eyes. "I'm being serious. When has Mari ever been the first to do anything with Matty? Not even Neevie or Sam have gotten him off yet."

Belle sighed and rubbed her forehead. "Can we not have this conversation?"

"Fine, fine, let's get to class," Alice conceded. "But you know this won't be the end of it. The others are all gonna wanna do the same. You know, so we're all still 'in balance'." Alice finished the last phrase miming air quotes.

I frowned. "Didn't you just say you wouldn't want to do that?"

Alice looked at me like I'd grown a horn out of my forehead. "No, eww! I mess around with you because it makes ME feel hot and sexy. I mean, I AM a little curious about you sucking on my titties. But I don't actually want your yucky sperm on my hand or anything like that. Like... Eww! But you know Sam and Neevie are gonna be all over that."

Belle grumbled, "It's not exactly 'still in balance' if only two or three of us can do something."

Alice furrowed her eyebrows and gave Belle an agreeable look. "That's a good point. We should take it up with Sam."

"Well can we do it at home?" I complained. "I really don't like having this conversation out in the open."

"Fine, fine." Alice held up her hands defensively and started walking. But she looked back at Belle and said, "Seriously though. I need your help coming up with some good and logical reasons why we collectively need to tap the brakes. Because ever since Matty became the BTC's official boyfriend, I've started panicking we're all somehow gonna lose our virginities before Christmas."

Belle snorted. "Don't worry. Things would never get THAT crazy."

****

"Oooh, oooh. I wanna try again," Alice chirped enthusiastically as she knelt before me in front of the couch and once again wrapped her hand around my thick and throbbing dick.

I groaned and let my head loll over the backrest, closing my eyes and relishing the sensations of my long-time friend pumping my naked prick with her hand.

Based on Alice's mood this morning, I would have NEVER expected to be in this situation right now. And yet here I was, getting my dick fondled by all six of the BTC girls.

Yes, I said all six. Even Belle had joined in. Well, I didn't know Belle was going to join in. I was a little busy sucking face with Zofi and therefore barely noticed when Mari quite literally handed my dick off to her best friend. Only when Zofi broke away to let Alice have a turn kissing me did I look down and notice the petite strawberry-blonde's small hands stacking up around my big dick with some room left over at the top.

I'm getting ahead of myself, aren't I?

At lunchtime, Alice had indeed raised the notion of tapping the brakes on our runaway hormones, stating that while the original intent of "The Rule" was for no one to literally "date" me and therefore take me away from the other girls, in practice The Rule had existed to keep everyone from getting too intimate with me. Physical intimacy and plain old "doing sex stuff" would put us on a path where somebody would get feelings that may or may not be reciprocated, somebody would get hurt, and in the end the BTC could very well fracture. As much as I'd enjoyed "doing stuff" with the girls, I couldn't disagree and figured that when we all ended up at my house this afternoon to hang out and grill dinner, per usual for a Friday, the girls would hammer out a clarified understanding of The Rule and we'd start rolling back some of the liberties the girls had been taking with my body lately.

I was exactly wrong.

Somehow, someway, as soon as we got to my house Sam convinced the girls that "fair was fair" and The Rule was about keeping a level playing field, not restricting the girls from getting too intimate with me.

"We're not fifteen anymore," Sam argued. "Aren't we mature enough to push our boundaries a little? It's not like I'm asking you to have sex with him. But if Mari is woman enough to explore her sexuality a little bit with the only man she's ever felt safe enough to explore with, who are we to say she's not allowed?"

That particular argument was what won over Alice. Naimh was already on the side of pushing those boundaries as far as they could go. Zofi was pretty chill about the whole thing, saying she'd go along with whatever the group decided. And of course Mari did NOT want to roll back being allowed to play with my dick and feel me sucking on her tits the next time there was an opportunity.

Belle was the lone holdout, and in the end she just threw up her hands, barked a little angrily, "Fine! You sluts do whatever the hell you want. I'm going for a walk." And then she went for a walk.
