My mind is going blank

Woo-Bin pressed the tip of his dick against Hae-won's entrance and he flinched. 

"Is it okay?" Woo-Bin asked, concerned and Hae-won nodded, though biting on his finger.

Woo-Bin proceeded and plunged the hole with his dick while Hae-won trembled violently.

'It hurts.' he held onto Baek-Hyun's arm tightly to the point of scraping with his fingers.

"Hyung, should we stop?" Baek-Hyun asked but he adamantly shook his head, though his violent tremble worried him.

"It's in now, right?" Hae-won asked and opened his eyes.

"Sun-bae," Woo-Bin called. "It's just the tip that's gone in." He said, shocking him.

"What?"

Without warning, Woo-Bin pushed in hard, causing Hae-won to see stars as he couldn't tell what type of feeling it was. It was painful and tears welled up in his eyes.

"It's half way in, Sun-bae." Woo-Bin said and looked up to see Hae-won in tears. 

"It hurts." He finally admitted. "It hurts too much. Wah!" He cried.
