While their dad went to go check them in, Rick and Sam took the opportunity to go check out the arcade. Though, arcade might not have been the best word for it, because the inside looked more like a carnival with tests of luck, strength, and skill games lining the inside walls. Rick was feeling himself when he saw a hammer game, thinking that he could just strong-arm it and win something for his girlfriend. Sam could have sworn that he and Rick started the road trip in middle school, but here they were graduating high school and talking about their dates. Rick took the hammer in his hands and felt his muscles activate, as if holding the hammer was making him grow and changing his body history.
Rick had always been an athletic calf, but his dad always loved football, so he trained up to be on the defensive line so that he could stay in his dad’s good graces, unlike his twin Sam. When Debra went to college, the family kinda drifted apart, the twins being the only ones that kept the family together. Sam had been bullied a lot in middle school due to her gender dysphoria, but her mom allowed her to get the treatment, and now she was a beautiful, buxom cowgirl that was finally comfortable being who she was, and found a beautiful cow to date her. Their mom was happy that she was happy, but their dad just grew frustrated and distant. Rick and Debra are the only ones that talk to him, but this trip would change all that. His football muscles grew in as he took the swing back, his abs popping out of his shirt and his legs and ass getting super toned. With all the power he could muster he took the hammer and swung it with all his might, tearing his outfit and leaving his black, furry body in all its naked glory for all to see as he watched his results with his flaccid yet massive bull cock.
As the hammer hit the board, the metal piece rose all the way to the top and hit the bell, causing the entire building to cheer. He got a cute little milk plush, took a pic of it, and sent it to his girlfriend with the caption, “Won this for you, can’t wait to see you again! ;)” Sam was cheering for her brother, she knew just how strong he was from their childhood wrestling and pranks. He was the stronger, hard-headed twin. Now Sam needed to win her girlfriend something, and found just the game to do it, Skeeball.
While Rick was the stronger twin, Sam was the smarter one, using more skill and hand-eye coordination to succeed. Even as a calf, Sam always had a knack for getting high scores in skeeball, it was her favorite game. She readied a ball, cocked her wrist, and sent it into one of the corner hole. She grabbed another ball and sent it into the other corner hole, repeating until all the balls were gone, getting a high score of 100,000 and breaking the record. What no one else noticed was that Sam was losing her clothing with each throw, her body expanding and growing chunkier, but voluptuous until she was literally naked in the arcade (just like her brother). Pure white fur covered her body as she gained not only milk filled breasts and sensitive teats, but an udder also full of milk that sloshed as she swing her body around. Sam’s light blonde hair grew down to her waist as she sported a cow tail and large cow ears. She’d become a dairy cow just as her twin brother had become a bull, but no one batted an eye at their naked state.
Redeeming their prizes, they left the arcade and headed back to the motel, where their father had left a note inside the RV telling them where the room was. Rick went in first, followed by Sam, who hesitated to even look her father in the eye. But after a few minutes of gas and laughs, the two of them had a heart to heart (with a little bit of convincing from Rick), while not totally fixed, they were at least in good terms now and could talk to each other without being frustrated or overly critical.
