Anal fuck to orgasm [FM]

Stressed about schoolwork, yet somehow alone in the apartment with my boyfriend, I felt myself getting wet. As a kinky individual I asked my boyfriend to Dom me, and soon enough I was locked in my leather collar. I lounged around a bit, and felt my libido crying out to me, wanting something, anything, even though I had just cum a few hours ago. I looked over to my boyfriend, and asked, “Master, should I give my pussy the ben wa balls, or plug my ass?”
“What do you want, slave?”
“I… what if slave wants both?”
“Ben wa balls first, then.”

I got up and walked to the toy chest, sleek and shiny ben wa balls in hand, I laid down on the bed and found the lube. Spreading my smooth pussy lips open, I fingered myself. Wet but not wet enough… I lubed up the balls and gently pushed them, pulling the string taut as I buried them deep inside. He was nodding in approval, “Good slave.”
“Thank you Master!”
