Anal sex on the back, on all fours and riding

The man roughly grabs the woman by her hair and pulls her into an intense 69 position on the floor. He ruthlessly rips off her panties and begins to finger her anus, stretching it open. The woman, moaning in both pleasure and pain, tries to resist but is helpless under his grip. He forcefully penetrates her anus with his fingers, filling her up and making her scream. The woman tastes her own ass juices on his finger as he teasingly licks them clean. His cock, now dripping with lube, rubs against her wet opening, causing her to beg for penetration. He grabs her waist and flips her over onto all fours. He slaps her ass cheeks and spreads her legs wide apart, forcing his cock into her tight anus. She screams in agony and ecstasy as he brutally fucks her ass without mercy.
