Blake finally turned 13 and it was his birthday. He woke up to find some morning wood. Curious he touched it and finally started to feel the erogenous feeling of a maturing dick. Mother nature had gifted him with the start of puberty... along with something else. Thinking he stopped playing with himself and got dressed and went downstairs for some breakfast. His mother and older 17 year old sister was downstairs and his dad was out on a business trip.
His sister Blare said "Why happy birthday my little brother of mine." and his mother said happy birthday to him as well. Blake gave them a hug.
His Mom said "Oh I've got some eggs and bacon out." Blake had gotten some food to eat. After the meal his mother asked "Blare you were going to drop Blake and his little friend off to the mall weren't you?"
Blare chuckled and said "Beats buying a gift. C'mon kiddo let's---"
His mother cut Blare off and said "Actually small thing." she got out on of her credit cards in her wallet and said "Go ahead and use this for some food and get yourself a reasonable gift. Nothing too pricey but I think I can trust you."
Blake took it and nodded with a big ole Thank You. A drive to the mall later after picking up his friend Courtney they went to the mall. Courtney was a bit... hyperactive in ways but was a fun friend to hang around with. The two were dropped off at the mall and Courtney said "Thank you Blaire! I'll be careful with your brother!" Blaire just waved away as Courtney took Blake's hand and they went into the mall. The two went through the mall looking at things but during the touching and contact Blake's little curse was going into affect.
Courtney's belly had started to round and her training bra was starting to expand and get sore. They took a break and as they took a break a Blake got a phone call. He picked it up and it was from his sister. Apparently Blaire and their mother's belly's were expanding and they were going to the doctors so they should get Courtney's parents to pick her up.
As he told Courtney this she felt her own belly and then noticed the lump and said "Actually I think something similar is happening to me... What's going on... Either way I should probably call for a ride home. As they were waiting for a ride home though...
