"It's getting bigger," Sophia gasped as she felt a new sensation inside of her.
After he helped her to her release, she was sensitive everywhere. Clarity came to her until she felt him swelling and the fullness made her feel hazy. Her eyes fluttered closed.
At his fervent actions, she knew she couldn't stop him, nor did she want to. She simply moaned and her dripping core told him all he needed to know.
The more he thrusted, the harder his knot became. In response, the harder she squeezed him and he could only act out of instinct as he fell into the mindlessness of such a pleasurable sensation.
If she wasn't an omega, her body certainly wouldn't have been able to handle the knotting of such a dominant alpha.
At his accentuated girth and incessant thrusting, Sophia could feel that she was on her way to another orgasm. The grip on her bedding tightened and her eyes fluttered closed.
