Beric instinctively moved his hand to Yeon Jin's hole and poked it with his thumb. He poked his thumb deeper and looked up to see Yeon Jin shutting his eyes and shaking his head.
"Mph! Mph!" He struggled but Beric held him down.
He took out his thumb and replaced it with his index finger, inserting it deep till it went in fully. He took out his finger till it was just the top left and inserted his middle finger as well.
Yeon Jin's legs trembled and his voice muffled over the cloth in his mouth but Beric did not stop. He kept shaking his head but Beric didn't want to hear what he had to say.
He started thrusting his fingers in and out of Yeon Jin's hole.
He was doing more than enough, going to this extent just to make sure he didn't hurt him while putting it in. If not, he didn't mind pushing his thing in and thrusting till he was satisfied.
This was the least Yeon Jin could do after betraying him by fawning over another man in front of him.
