“You... Matty. This... chemistry... between you two. It's been obvious since you two first met. We can all see it.”

Naimh blinked. "You want to have this conversation now?"

“Sure. Why not?"

Naimh gestured with her free hand, miming up and down in sync with the way Belle currently undulated up and down in my lap. The petite teen girl was riding me reverse cowgirl on the armchair in the family room, you see.

Belle just grinned, clenched her cunt muscles tighter around my cock, and continued. "So? It's not Like my mouth is busy at the moment."

Naimh chuckled in amusement and thought about her response. "You know,

I could ask you the same question. There's obvious chemistry between you and Matty. Everyone has always known you two are really close, and these overnights you get to have with him now are only going to amplify that."

Belle shrugged.

“Matty and I are an open book at this point. Much as I complained about him seeing me as a ‘little sister’ for so long, that's actually a pretty apt description of our relationship."

Naimh mimed with her hand up and down again. "Most little sisters don't do THAT to their big brothers."

Belle giggled, which did wonderful things to her core muscles for me.

“Perhaps, but then we're not actually related. So... call us ‘siblings with benefits’? And didn't the group of us have this conversation in

Tahoe?"

Naimh shrugged.

“You said you loved him, and would always love him, and fantasized about marrying the boy next door and never feeling alone again for the rest of your life.”

Belle stopped humping for a moment and glanced back at me. Somehow, none of us had ever completely removed our shirts, although we were completely bottomless from the previous round and I had my hands slipped underneath the hem of Belle's shirt so I could play with both of her boobs. Presently, though, I Let go of her tits to instead wrap my arms completely around her body and hug her tightly. Belle cooed and kissed my neck while I bent my head over her shoulder, squeezing me tightly.

“Yeah, exactly," Naimh drawled.

Belle sighed and looked back at her friend.

“I love Matty. But I also told you in Tahoe that I enjoy watching him fuck all my friends. I

REALLY enjoyed watching him fuck you earlier. And I care too much about the BTC to ever seriously consider making him my boyfriend."

"You said he offered. Why not make him your boyfriend but give him permission to fuck the rest of us? Best of both worlds, right? You get to be with the man you love AND enjoy your voyeuristic side."

Belle pursed her Lips. "The thought crossed my mind. But..." Her voice trailed off.

“You wouldn't want to betray the BTC?"

“Sort of," Belle conceded. "I mean, that's your reason, isn't it? The thought that if he became your boyfriend, you'd be taking him away from the others?"

Naimh nodded.
