A vocal wife mounts a friend and reacts loudly as she bounces on his cock. She then gets off and the guy fucks her in missionary position. She again reacts very loudly once he starts pounding her. She’s not the only one whose vocal, the husband clearly enjoys watching his wife get fucked well. He encourages the guy telling him to “fuck her good, she loves it”.
The husband calls the guy by his name, therefore, I’ll conclude that the guy is a lover who probably has been with the wife before. This means the friend tag. Also, the video title refers to the guy as a “buddy”.
