Submissive girlfriend is the birthday gift

It's the boy's birthday and she's making him breakfast. To make the surprise complete, she wakes him up with a delicious blowjob. The boy is happy and sends her to get the handcuffs, immobilizing her with her legs open and gagged to fuck her hard. She can only enjoy it while the man takes out his gag and puts his fingers in her mouth while he fucks her. Then the boy lets her go by fucking her violently until she sucks him and jerks off his cock making him ejaculate
