Tony said "Sweet. I get to roll again and my role counts for double the normal amount!"
Claire said "Remember we aren't trying to reach the end, we are trying to have a child before we reach the end..."
Tony said "Whatever i'm rolling again." he threw the dice and they landed 1 and 3 making his piece start moving 8 spaces. Claire then read the rule stating "The farther you move into the game the older you get in real life, excluding the start. 1 year per space and there are 100 spaces." She was happy that she wasn't 3 years old but she did the simple arithmetic 6 + 8 = 14 and then understood the implications. Large growth and puberty, and the rush of hormones may make him horny.
As Tony's piece was moving it was growing along with Tony who asked "Claire does the rules explain anything about what's going on?"
Claire said "You get a year older for every space you move, not including the space leading up to your actual age... So now you are getting older." The piece was moving slowly and it had moved 3 spaces so far and the 9 year old Tony's clothes were starting to get tight. The piece gained some speed and rushed to space 14 where Tony's clothes burst from both the piece and Tony.
Tony felt weird and asked "What's going on my pee pee feels weird." he then started to poke it and it hardened
Claire got embarrassed not because she was seeing a naked teen but through being embarrassed by having to explain to Tony what puberty was and how it worked into making a baby.
Tony continued saying with a smile "Well then just roll some doubles and let's start making a child... Hurry please."
