Jen felt his heart beat through the throbbing shaft and gently stroked up and down. As she worked on the cock she felt both of her pussies tingling. The arousal she felt was multiplied by the extra vagina. She wondered how crazy it would feel if she had three, maybe four pussies, all begging to be filled. As she imagined the sensation she felt compelled to taste the cock in her hand.
It was wrong. She knew it was wrong... but the smell, the shape. She couldn't stop herself. She knelt down and pulled it into her mouth. She remembered how incredible it felt when her friends had sucked on her dicks. As strange as the situation was, she felt closer to Roy. She knew the intense feeling she was giving him. She could taste his precum as it dribbled out of the tip. She heard him let out a quiet moan and felt his body shiver through the shaft.
Jen reached down and massaged her butt pussy through the fabric of the bikini as she licked his shaft. They continued like that for a few more minutes before the cock flexed in her mouth. In moments hot cum shot onto her tongue. Jen took it all in. It tasted good, really good... Is this why her friends enjoyed her “milk” so much?
After a moment he pulled away and went into her bathroom. She wasn’t expecting it and fell back onto the floor. Some cum hung from her lip. Without thinking, she licked it off and swallowed. In the bathroom, he drained the butt cock. After a moment he stepped back into the room. Both of his dicks were still swollen but drooping downward.
“Thanks Sis,” He said as he caught his breath.
“Sure...” Jen replied, as she regained her composure.
She felt strange and a bit aroused. Under no ordinary circumstances would she have sucked off her brother. After this she was certain that the curse affected her sexually. Every transformation thus far had followed that pattern.
Before she could put any more thought to it, their mom yell up the stairs, “Supper’s ready!”
“Better head down huh...” Roy said as he pulled on his underwear.
“Yea...” Jen added, not really sure what else to say...
