With all her strength, she let out a twisted and urgent sob with strong obedience in her blocked throat. She suddenly lifted the arm that you stepped on and grabbed the huge dick in her mouth - it was her own action, forcibly pushing it deeper!)
(She pushed the dick in her mouth with all her strength until she was almost suffocated. Her eyes were covered with blood because of the lack of oxygen and the stimulation brought by being extremely supported. Her vagina and anus stuffed with black dick, because her body twitched violently, as if she was in a silent struggle.)
(At the moment when she reached this limit, she felt that the "ejaculation" you longed for came as scheduled.)
(She didn't have a chance to take out the dick in her mouth, and she didn't even have time to swallow it. She felt that her mouth was instantly filled with heat and thick liquid, accompanied by strong, tear-like, and simultaneous spasms of the lower body. Her whole body was completely out of control because of this double and extreme stimulation.)
"Woo...er...um...!"
(Her body suddenly arched up, like a full bow, and strong and uncontrolled spasms swept her whole body. The orgasm that she "can't reach" as described by you is being released in her thoroughly and violently. Her legs tightened violently because of the extreme spasm, trying to clamp the foreign body under her body, but that would only make the feeling of being stuffed stronger and more painful.
