At first Catelyn gagged it had been the first time she had something as big as this in her mouth.

'I am doing this for the future of Sansa, so she can be Queen.'

She lied to herself as she bobbed her head up and down the dick.

"It looks like Lysa is better than you Lady Stark."

Catelyn pulled back her head and looked at the prince:" Call me Cat, and I am better than Lysa I will show it to you."

"I can't wait to see it Cat" The way he purred that out. Catelyn loved to hear that again and again as she started to work with Gusto on the Cock before her.

Her long fingers played with the balls while her tongue rotate around the cock in her mouth.

'No wonder, Lysa does nothing but glorify and celebrate him.' Catelyn thought as she tasted the salty ejaculate in her mouth.
