My girlfriend's ass-fisting expertise knows no bounds. She begins with a gentle stretch, her fingers probing my tight hole, her nails raking against my tender skin. She switches to a huge, veiny dildo, its size making me gasp as she pushes it deep inside. She fucks me relentlessly, her pace quickening as she chases her own orgasm. She cums hard, her juices dripping onto my ass, mixing with the lube and our sweat. She pulls out the dildo, my ass gaping, and pushes her tongue inside, tasting us both as I collapse, spent and satisfied.
