Humping a Chair, Fingering My Ass, and explosive Cumming with my Ass Pulsing

I spread my legs wide and leaned forward onto the chair, feeling the cool surface of the wood against my pounding heart. I slid my hands under my butt cheeks and teased myself, noticing how my insides were aching for pleasure. I kept moving my fingers deeper inside me, increasing the intensity as I felt my body begin to pulse with anticipation. The sensation was building up until I felt my muscles convulse and I released a moan of sheer pleasure as I cummed hard, my ass cheeks quivering with each glorious wave.
