拳头被简单地推进去，没有预伸展

When the doorbell rang, I was kneeling in front of the couch and spread my cheeks. Today it will happen, I knew that. I had prepared everything so that it could start immediately. The horny guy came in and grinned at the sight of my begging asshole. He quickly pulled on his gloves. With a strong breath and plenty of lubricant, he immediately pushed his clenched fist through my sphincter and began to punchfist me. This is awesome! Without much blabla just straight in the ass.
