“I’ll try being Aunt Carrie,” Jeff said “I think it would be fun being spending the weekend as a sister to you Mom.” When his mom mentioned her sister Jeff’s first thought was that his aunt wasn’t really a great sister. She hardly ever talked to Sherry and when she did it usually ended in bickering, maybe Jeff could let his mother have a good weekend with her sister. “Okay sweetie,” his mother said “If that’s what you want.” She sounded a little sad but she wasn’t about to force her son to be her if he didn’t want to. “And if we don’t set the change up perfectly this will eliminate any awkward situations with Dad.” Jeff said with a chuckle. This comment got a good laugh from his mother who couldn’t help but agree at her sons statement. “True, we wouldn’t want you ending up in bed with your father if he was feeling a little frisky.” She said as she started typing into the computer. As she finished entering the change into the program she hesitated at hitting start. “You sure about this hon? This is going to be a weird weekend.” she said. “I’m sure, let’s get this weekend started sis.” As soon as Sherry hit start Jeff started feeling a bit weird, his legs got a few inches longer bringing his height to the same as Carrie. The next thing that happened was his hair started growing, he felt as his Adam’s Apple shrink and his face changed to that of his aunt. His arms and upper body slimmed down as well as his waist giving him the start to a beautiful figure. His shirt was a little loose at this point but as his thighs and hips plumped up his pants were soon a couple sizes too small and he let out small cry of pain as his balls and penis were being crushed. “Sorry Jeff,” his mom said “I wasn’t thinking of clothes.” When his butt expanded it was too much for his jeans and they ripped at multiple points in the seams. Jeff soon felt some relief as his penis and balls shrank giving way to her new vagina. Sherry was watching in awe as her son slowly but surely became her sister. “Only on thing left now.” Jeff now Carrie said. She could feel a tingling in her chest as her new breasts grew to a nice DD filling out her loose fitting shirt. Both women sat in silence, amazed at the transformation that just took place before their eyes. “How are you feeling honey?” Sherry asked. As Carrie was feeling her new body her hands stopped at her boobs, gently lifting them she answered “I feel amazing Mom! This is so weird but awesome at the same time!” In her excitement she rushed over and hugged Sherry, the new sensation of her boobs being squished by the act filled her body with a wave of heat. Sherry returned the hug enjoying how much fun her son was having but broke the embrace to look her new sister in the eye. “I know you’re feeling great right now but we need to get you out of those clothes, it’s time to go shopping.”
