Rubs her crotch on your face.

Lying there on the damp sweat smelling bed Tyler tried to regain his breath and senses as the sour and damp stench soaked in all around him. As he tried to pull himself up he felt a thudding jolt on the bed as Katelyn crawled onto the bed as well. Her massive frame looming over him and her titanic chest casting a shadow on him. Her body straddling over him as she looked down on him.

"Oh god, I can't wait."

Those were the words Tyler heard as sudden Katelyn shifted. Pulling down her tight stretched skirt as her skin became more and more apparent. With the skirt flopping off her legs and onto the floor, her floral print panties were put on display. The set of underwear already dark and damp from excessive use. As she began to move her hands pulling the underwear off it became obvious as stuck it was to her with slimy and sweat and other natural juices. Pulling it away it was still connected by a long line of slimy girlcum. She took them off and dropped the wet clothing right onto Tyler's chest.

With her damp pussy now free the stench in the air intensified as the sour smell of sweat and human bodies flooded the room and clung to everything. She slid herself forward so that her pussy was right in front of his face and the heat coming off of it soaked into his nostrils. He tried to move away in surprise but was unable to move with her massive frame crushing down on him and keeping him pressed into the mattress.

"WAIT, PLEASE DON--"

His words were cut off as she suddenly lifted herself up before slamming her crotch down right onto his terrified face. He could feel all the heat and damp sweat being shoved and **** onto him as the air was knocked out of his lungs and his entire face was covered in moist horny pussy.

"SHH, Don't worry about this. We'll feel so good together." Her muffled voice reached his covered ears as she began to move forward. "This'll be perfect training for you and your new position. Now I just need you to lick and eat me up. I'm already so close, so you just need to get used to my weak pussy."

She started to move, rubbing her pussy up and down on his face as his nose poked at her entrance and her slime soaked into his skin. He could feel the unbearable heat and horrid slime covering him as he seemed to flinch at the entire situation. More and more drops of sweat and slime dripped onto him as he closed his eyes and her rancid smell plugged up his nose with the smells of an overly horny bitch. Even despite his **** did some of the liquid enter his mouth and the sour taste of sweat and cum stuck to his tastebuds.

Tyler hated this. He didn't want to be some giant bitches plaything. He especially hated that it was his sister doing this to him. Treating him like a toy as she tried to get her nasty horny pussy off on him. He hoped that if he just played dead that it would all end like some sort of bad dream. Minutes passed like this as she continued to rub herself off on him. It was rather sudden when she finally stopped and just sat there on top of him.

"Ugh, if you're not gonna try then ill have to give you some more incentive."

Tyler wasn't quite sure what that sentence meant, but he didn't have long to puzzle over it. Right as his thought turned to this being nearly over he felt a massive blow of pain from his crotch. The pain rocketed up through his entire being and his mind went blank from the immense pain that throbbed away. He went limp and barely heard her next words.

"Get to work if you don't want me to give that cock of yours some more ****."

With his mind scrambled from the pain he reluctantly decided to follow her directive. He had felt the full **** of her slap in that blow and he knew she wasn't kidding. Rather than being in a world of pain he'd better do as he was told. With great **** he opened up his mouth a small amount. Her slimy and sour girl cum dripping into his mouth and covering up his tongue. He almost started to gag and cough at the horrendous taste that flooded his tastebuds. The only thing holding him back was the threat of more ****.

Still reeling from the shock that was up through his entire body Tyler slowly extended his tongue until he was ever so slightly licking at Kate's crotch. The sudden tingling sensation reverberating on his tongue as her deep horny flavor. With a sigh he stretched his tongue further as he began to work on her pussy.

"MMmmmmm, Thats the way to do it." Katelyn moaned out as she felt his tongue exploring her folds. "Be happy that your eating up my horny pussy and not my smelly asshole Ty."

She said this teasingly as she ground her pussy on his face. Spreading the thick juices leaking out and pushing his tongue even deeper into her folds. This went on for several minutes as she continued to use him to bring herself pleasure. The suffocating weight on Tyler's face made him even more **** as he fought to get air in his lungs and drove up the pleasure.

Katelyn could feel the pressure building up deep in the pit of her stomach as she began to moan out loud in pleasure. Her movements became more frequent and wild as she bucked and thrusted away on his face. It was then that she began to shake as her pussy started to quiver. Tyler had almost no heads up as a hose of juices sprayed onto his face. A flood of her orgasmic girl cum soaking into him.

Finally Tyler saw light once more as Katelyn got off of his face to admire her handiwork. The soaked and smelly Tyler just laid there in a daze, barely noticing anything as he tried to regain his breath. He was only startled out of the state when he had Katelyn's sweaty wet t-shirt land on his face. He pulled it away and looked up to find her stripping down in front of him until she was completely nude in her new form.

"That was a great start, I can't wait for the training to really begin."
