The bell rang to indicate the end of the lunch break, so Jen got dressed just before going to the next class, which would be arts. Getttin her clothes, she saw that there had been changes. Her skirt was nowhere, but she had a pair of jeans that fit her perfectly, which had two zippers that Grace and Milly passed through, as well as two holes in the back for Kyle's eyes. Her panties were totally wet due to the accident before, so she had to be content to be without panties under her pants. Her blouse said it had two extra holes, through which the heads of her cockgirls passed.
Upon leaving the locker room they met Lina, a classmate who now had her twin sister (Tina) as her dick. Lina was wearing a top that highlighted her six breasts and a skirt, which her cockgirl sister raised so that whoever was in front could see the shape of her ballbreasts in her panties. Tina was using a sock with an opening at the end for her head.
"Hey guys. So that's where you were all the time? I noticed that you didn't go to the canteen for lunch." Tina said
The girls remembered that with everything that happened they didn't eat anything, they were starving, but Jen responded by saying "We brought our own lunch, we've never had anything so good before." Soon after, their hunger disappeared and they felt totally full.
"Nice. But next time I want you to bring something for us too." Lina said
"Now changing the subject, what is our next class anyway?" Tina said
Grace answered, feeling compelled to lie "It will be the sex class." Milly and Jen looked at her, also surprised at what they had heard her say. Then they looked at the twins who walked beside them. They saw Tina get hard
"Great, and our favorite subject. Don't you think so?" the twin sisters said at the same time.
"Yes, we love sex class too." Milly responded, now also under the effect of the curse and feeling compelled to lie. Soon she and Grace were also hard, as the two stick girls and Jen had been very interested in the next class. It didn't take long for them to get to the sex classroom, where they didn't have desks but beds. The surrounding walls were covered with posters with models having sex in several different positions, each with a caption that gave a quick introduction to it. Jen chose a bed and sat on it, which Lina sat with them.
As soon as they sat down, Mrs. Longshaft (Of which she had her husband, who had not worked at school before, as her dick now), who was the art teacher and now was the sex teacher, told them to take off their clothes and put them away. Everyone obeyed her with pleasure.
"Today we will have a practical class. Get together in pairs and take turns fucking your partners." Mrs. Longshaft said,
Jen, Grace and Milly agreed to do the lesson with Lina and Tina, but Milly and Grace started to discuss which one would be used to fuck first.
"Stop fighting. Jen, as you have two dicks you will need one more partner. Kevin and Dani, join them." Mrs. Longshaft said
Kevin went quickly to the bed they were in and joined them, Dani hard between her legs said "It will be a great pleasure to team up with you."
The girls then discussed who would start fucking and which position, deciding to start with Jen fucking doggy style. Lina and Kevin stood on all fours on the floor with their backs to Jen, who knelt behind the space between them. She pushed her hard cockgirls down and aimed them. Before any penetration the cockgirls stimulated their partners to excite them even more, Grace sucking the nipples of Tina's ballbreasts and Milly using her tongue and nose to stimulate the edges of Kevin's pussy.
Kyle, having also been affected by the girls' lies, felt abandoned being Jen's ass, so he tried to get revenge by letting go farts to spoil the mood.
"Is Kyle trying to ruin class again?" Kevin asked
"No. My farts are aphrodisiac gases, Kyle is helping us to do our best." Jen said and immediately a smell of you came up in the air, which she unconsciously knew was Kyle's farts, making Grace and Milly feel even harder. Then she pushed her cockgirls into the pussies of the girls on all fours in front of her, putting them all in one piece before starting to manage her movements. At this time Jen was grateful for the changes in reality, otherwise both Kevin and Lina would have been killed with dicks so big inside them and Grace and Milly would be suffocated because they couldn't breathe with their heads inside the girls.
In a few minutes Jen came, feeling a great amount of cum traveling through her cockgirls inside her partners, she can see her partners cumming too, with the cum coming out of Tina and Dani's mouths. Jen took Grace and Milly out of the girls and sat on the bed for a while.
