Tell her you know another way
From Create Your Own Story
"I'm not sure I'm ready for this babe. But maybe if we start somewhere else I'll warm up to it." You tell her.
"Okay babe, I understand. Do you want me to suck your dick?" She asks.
"No I was thinking of another hole." You respond cheekily.
"I don't have a pussy anymore babe." She expresses.
"What about your ass?" You respond.
"Well I know we tried before and it didn't really work but... I don't know if I'm ready to try again. I think it's to tight." She says cautiously.
She's right last time we tried I couldn't get it in. Her ass is really tight.
