The three of us were hanging out like we always do, but then you left the room and things got carried away. I forgot it wasn’t you under the covers and I accidentally hooked up with your best friend. He made me cum, something you never do, so I thought it would be a great idea if you watched him fuck me and learned a few things. He’s your best friend so you can trust him. It’s not like you’ll always be a cuck, just when the three of us hang out.
