Grace was exhausted.
Heinz was like an engine that had been running all night. He didn't allow either of them to rest at all.
All night, the engine kept going.
Heinz was way stronger than Grace and there was no way she could physically overpower him.
In the end, she was basically half conscious. After a short while, she would be awakened by Heinz.
However, she really had no energy, so she could only endure it. She wanted to tell him not to continue, but after a few times, she lost her mind because of him.
She was half conscious, swept along with his rhythm.
At dawn, she opened her eyes and felt a headache coming on.
The whole night seemed like a long and exhausting dream. Her whole body was in pain but it was a passionate pain.
She sat up, patted her face, and turned her head to look at her side. However, no one was beside her.
Where had he gone?
She quickly came back to her senses and looked at the bathroom, but there was no sound.
