"I want you to pretend that you have a clit on your ass. Don't touch it just yet. Just think of how good it would feel when you took your finger and slowly rubbed your asshole like a clit. Slow circles rubbing your clit while the pleasure builds up"
"Keep that cock hard for me at all times"
"I will not be happy if I want to use your cock and it is soft"
"I want you to take your cock ring or shoe lace and tie your cck up just tight enough that it stays hard"
