She takes Tyler to her room.

With a grunt Tyler was pulled into the house by his now supersized sister and her brand new strength. The breath was knocked out of his lungs as he was yanked into her strong embrace. Katelyn grabbed him tightly in a bear hug, pulling him up and into her massive sweaty boobs. His body was like a limp ragdoll as he was easily lifted into the air.

Tyler suddenly found himself being smothered in a soft yet sweaty world. He could feel her tight grip around his waist squeezing the air out of his lungs. Instead his lungs were being filled with the musky stench coming off of her breasts. The damp pillows wiping on his face and coating him with the strong slightly milky scent.

"Oh I'm so glad your here. You are just so cute, and we have really been needing someone like you to help us out. Oh, I can't wait to try you out. Plus they'll be so pleased to see you."

Tyler heard those muffled words as he felt Katelyn began to move, carrying him inside. Her strong embrace not letting up as she moved through the house. Every movement sending shakes through her body as Tyler found himself fighting for air around the massive breast pillows that kept slamming into him, and knocking the air out of his lungs.

A door slammed behind them as Tyler felt them stop moving. When he wondered what was next he suddenly felt himself being released from the tight arms that held him as he fell backwards onto the bed that had appeared below him. He laid there in a daze as he tried to get his bearings. He was now damp with tit sweat that had come off of Katelyn and had stuck to his body and began to soak into his clothes. The smell of sweat was strong and filled his lungs with a sour taste, but an even stronger smell had also appeared, a sour musky scent that took him sharply by surprise.

Looking around he realized that he was now in Katelyn's room having been thrown onto her damp bed as she stared at him from above, Looking down on him and casting a shadow over his form as he could see her breathing deeply. The bed around him seemed to cling to him and prevented him from getting up before catching his breath.

"I'm sorry bro, but with you here I just can't control myself. I need to do this."
