Joining the Beta (boyxgirlxboy)

"Why are you not wearing any pants?" Gannon growls, slamming the door and stalking across the room towards me.
I shrug. "Pants are overrated."
Gannon pulls me up.
"Mine." He growls in my ear. "Only I get to see what's mine."
"Pft," I snort, wrapping my arms around his waist and making eye contact with an uncomfortable looking Grover over Gannon's shoulder. "It's Grove."
I see Grover wince and his eyes drop to the ground. My heart clenches and I hope my next words will wipe away the sting of what I've just said.
"We both know how much you love it when Grove watches us." I whisper in Gannon's ear. Gannon growls and presses his hips into mine. Grover's eyes rocket up to meet mine. I smile encouragingly. "We both know how much sexier it is when you know Grove is right outside listening to every groan and moan. We both know how much you want him to join us."

This book is straight up smut with a side of plot line. There will be mXmXf and mXf and probably some mxm and if I can work it in, some fxf. There will also be some BDSM because... well... yum. You've been warned to read at your own risk.
