It's been two weeks since James has been mapping an exit to get out of the cabin. Every day he would leave and for a couple hours map out the forest surrounding the cabin. But something didn't make sense because after a couple days he started marking up trees so he can find his way around easier but everyday those markings would disappear making it impossible for him to find his way around. They were truly stuck here at the cabin.
And to make mattes even worse James horse cock needed release, it's been so long since he had sex and his new feature wanted a go at it and today while he was searching he couldn't take this sensation any longer and went back early to the cabin

Jess had waddled her way out of the back door of the cabin and slumped to the ground just outside the door. Every emotion inside of her way at war with each other. She loved her dad, she wanted him, but this was wrong and she couldn't do it. But it felt so good and she was sooo horny, but she couldn't have sex or else she would change. But over these emotions something resided allowing her to stay horny and that was she wanted to lose her virginity and she wanted to lose it right now.
She unstrapped her dungarees and started rubbing her huge fleshy breasts on the ground and start to stimulate them as she pointed her ass in the air. It felt so good to Jess and she kept doing it but failed to notice someone sneaking behind her.
"Jess?!" James exclaimed in panic.
"Ooh heey James" Jess said currently being lost In the sensations. "You wouldn't mind fucking me would you with that nice horse cock would you?" She asked.
"I-I" James stammered and he started to take his clothes off. He wanted this and his sisters sex was right there in front of his face waiting. He could smell it, the nice smell of Jess's pussy was waiting for him. Until all his clothes were off and he plunged his cock into her vagina.
Jess gasped in a sign of relief as James entered her. This felt so good to Jess and she felt warm inside and bubbly. James cock was able to reach all the way in and touch the end of her cervix and started thrusting. This felt like heaven to the both of them but James realized changes were a foot as Jess felt something happening behind her. James watched as Jess's skinny body widened at the hips and her ass swelled giving her remarkable curves. James liked this change and was so far into this himself he neglected to realized his balls were changing, becoming darker, dropping and becoming large, a horses pair of testicles James now owned as he sent Jess and himself to climax.
James exited his sister as both sat there James now mesmerized by his sisters sexy curves now ever than before.
