He was deeper than before, far deeper than she thought she could accommodate him.
He one more time pushed her up and before he could slip out, he pushed her back down. He repeated the process until he was sure she got it.
She continued- she continued the process on her own until she was used to the pain and until the pain became more pleasurable.
She then lowered her knees on the bed and he hugged her waist, urging her forward. She got bold and increased her pace, it felt good as an unexplainable sensation washed over her with each movement.
