It's kind of both

René wasn't actually being pushed by her mother at least not terribly hard. While Grace had passively removed any disgust at the idea of incestuous relationships she wasn't exactly pushing her daughter and son together with any particular aggression.

Rene looked at her brother examining him closely for a moment Before shrugging her shoulders.

"You know what that is a fair assessment,:" He said grinning playfully, "Or maybe you're more like Mom and me than you want to admit," he added wiggling his eyebrows and grinning playfully.

"You're thtill The bigger pervert," she added leaning in, squeezing one of his softball-sized breasts.

Adam grinned stopping the car and wrapping his arms around his sister pressing her massive breasts against his smaller ones as they shared a perverse taboo Kiss.

"Give me time and I will find out what makes you tick," he responded unlike her he had been fantasising about this for a while.

"Tho, how are we going to play thith?" lisped Rene
