Substitute [2]

Auntie felt good, and Elmer felt even better. The pleasure of being tightly penetrated in the rectum could only be experienced through practice.

Elmer used to watch American porn with anal sex scenes, and every time he saw a thick penis entering the actress's anus, the actress's expression was very lewd.

Elmer wondered if anal sex was really pleasurable. Once while taking a shower, he even tried to insert his own finger into his anus.

When his finger entered, Elmer felt a little weird and quickly pulled it out. But now, as he penetrated Auntie's anus, Elmer felt extremely pleasurable.

If it were a stranger that he was having anal sex with, Elmer wouldn't be as excited. But since it was his own Auntie that he was having anal sex with, he couldn't help but feel excited.

This was incest, the legendary incest. Under the influence of blood ties, Elmer's thrusting speed became faster and faster.
