It was her older sister, Skyler, back from her geographical study in Scotland and waiting for someone to answer the door and find out she was back. Surprisingly, Jen's mom answered the door, with her recently gained attachment hidden away in her underpants. Jen's sister was academically and physically gifted with an IQ of 186, ambidextrous writing, extremely athletic, ff-cup breasts, an ass naturally bigger than Kim Kardashian, 6'4 tall with her legs making 60% of it, perfect hourglass figure, mid-back length brown hair, large pussy with visible clitoris and perfect make-upless complexion, as such many guys pined after her but she refused all of their requests of dating, reason: she was a lesbian and had a girlfriend since the age of 13. Jen thought hard on what she could do to her, she had figured out that the reason she now had her beloved horse penis must have been through the town curse: transform or dare. She also figured that she must have the curse but first, she would ride her sister. She snuck up on her and poked her on the back and said, simply: "I would like to ride you". Skyler was confused, since when had Jen been a lesbian but then she noticed the bulge in Jen's trousers, "Since when did you have a penis?", Skyler asked in a surprised but not disturbed ton.
"Since earlier", Jen answered rather plainly.
Skyler knew not to ask anymore when Jen had that tone, "About that idea of riding me, let's do it".
They quickly scrambled to Skyler's, for some reason soundproof room.They clambered on to her bed where they got naked and that is when Skyler saw Jen's horse cock in all its full glory, Skyler was pleasantly surprised but asked no questions and instead started to such it, this caused Jen to go, almost instantly, into an orgasm. Skyler then started to deep throat the cock which is when cum started pouring out of the head of the horse penis, this lasted for about a minute. Jen then pulled her penis out of her sister's mouth and shoved it into Skyler's pussy, pumping at a fast rate making both girls orgasm for 5 minute, which is when Jen stopped riding Skyler and asked: "Transform or Dare?".
