Brotherly love

"Fine, but we can act it out instead of talking about it," Jacob said, his face turning dark red. "Just remember...you asked."

Before David knew what was happening, Jacob stepped into the bathroom and right up behind him. He could feel the bulge of his son's cock pressing against him through his clothes as the boy wrapped his arms around him and pulled him into a standing position.

"Rach, I'm sorry you caught me sniffing your panties," he said as he held his father tight. "Its just because I love you so much...and they smell so good. Please don't tell dad."

David was not sure how his son wanted him to play along, so he just stood their awkwardly. As he spoke, Jacob was grinding his cock into his father's borrowed ass.

"You're just so amazing, I couldn't help myself," Jacob continued. One of his hands slid upwards and took a firm grip on his sister's breast. "You deserve better than those garbage boys you've dated. You deserve a man who will treat you like the queen you are. You need a man who will worship every inch of you."

Jacob gently squeezed his nipple, and David let out an involuntary moan of pleasure.

"No, it's not wrong!" the boy said, sticking with his side of his internal script. David wished he knew the other side. While one hand continued to play with a boob and nipple, Jacob's other hand slid down to his father's pussy. "Please, don't call me a pervert."

"But your such a perv," David said, hoping he'd picked up the right line.

"How could you say that?" Jacob asked. The hand teasing David's pussy moved away, and a second later he felt warm, hard cock against his backside. "I'm just trying to show you how much I worship my baby sis."

"I'm telling dad!"

Jacob grabbed him by the shoulders, spun him away from the full length mirror and towards the bathroom sink. David was surprised by how powerless he felt in his son's hands. The boy then gently pushed him forward, bending him over the sink.

Although slightly disturbed that this was his son's fantasy, David couldn't wait to see what was going to happen next.
