Just then, Jen's sister Sam enters her room to continue a search for her homework. In the process of looking, Sam turns around and freezes. Jen watched, horrified, as a fleshy tube as thick as her leg shot out of her stomach and into Sam's ass. Sam continued searching, causing Jen to shudder as she felt her dick rubbing on sheets and carpet. Jen did not want to sound like an amnesiac crazy person so she instead attempted to probe Sam's mind for answers. She finds out that Sam is not required to wear any clothing, despite her being both a human and a cock, and therefore either goes out naked or wearing extremely skimpy clothing. Jen can also wear whatever she wants, but in an attempt to lead a normal life, ends up wearing pretty much the same clothes as she did before the curse. These were probably because of the whole 'not effected by taboo' part of her curse, meaning, Jen shudders, she could - or more likely, Sam - perfectly well preform sex in public or even incest!
"Found it!" Sam shouts, leaning over the last place she would look, her backpack, "Ok jenny, I'm going to eat something, see ya down stairs!" And Jen returns to probing
Three minutes later Jen had found out that A) the cord keeping them together can stretch infinitely, proven when Sam had taken a trip to Mexico with her Spanish class and a fleshy pink tube stretched down across the country. B) Jen still had her vagina, almost hidden between Sam and her legs. And finally C) that Sam was currently fucking their mom, trying to impregnate her, if the intense pleasure and loud moaning coming from downstairs were anything to go by.
Jen collapsed as Sam reached orgasm, sending gallons upon gallons of hot, fertile sperm into their mother. Jen rushed downstairs as soon as she recovered, amazingly still feeling that Sam was ready for more. "I want a sister-daughter!" Sam was saying as she pulled out of mom, coated in both genders' fluids. Mom got up and handed them their waffles. It was weird for Jen to feel stuff enter her penis, but she did not say anything because she should be used to it.
They climbed on the bus, sitting both near the front and on opposite sides to create a tripwire. They successfully tripped four people while making conversation, and in Sam's case fucking, with the people next to them.
Jen had a hard (ha! Puns...) time focusing on schoolwork as Sam seemed to never run out of semen and just fucked and masturbated through the entire first half of the day. Because they were in different grades, (that made moving up to the next school a challenge) they had different lunch times meaning that there was a long cord stretching from the cafeteria to Sam's math class. Jen was attempting to eat through the sex, but found she could barely swallow. She looked pleadingly at her friend Katie and asked her "could you stop S... SAM! Oh FUCK!", cumming at the end.
Katie nodded and left, following the trail. Soon, Jen no longer felt the pleasure of sex and was able to eat the rest of her food while Katie walked back to the table. After lunch was over, Jen saw Sam walking in the hall, coated in cum and completely naked. Sam waved before diving into Katie's pussy. Jen was starting to get used to long distance pleasure, but seeing it in person, watching her sister thrust her head in and out of he best friend was too much. Jen started screaming louder than Sam or Katie, and before long, she was cumming buckets into her friend before Sam pulled out, still cumming, and got jizz all over Katie's clothes. "I'll see you again after school, Sam!" Katie called as they each went their separate ways. Jen took off her bra and shirt as soon as she got to class because all that sex had made her too hot to wear it. She had ditched her soggy panties a long time ago, so she was now only wearing a skirt, socks, and shoes. Because history was really boring and she wanted to try to see from Sam's eyes, she focused and found herself seeing...
