Actually, Free it's not meant to be sexual base (I honestly don't think Ellri has the drive tbh  >_>) as much as hint to the fact Angie can have multiple births showing her DNA isn't completely human anymore.  Ironically, as I recall in the mibbit chat, we ended up talking on this subject matter and it was more artistic rather than perverted. Mainly why and how to accommodate for the changes which, I will admit was interesting to listen to from a point other then perverted.  

It was mentioned that mammals like canines and what not, actually have multiple (I'm going to use feeding spots rather than nipples here, due to how risky this topic is and I much rather not get banned, folks) feeding spots since they would have more than one offspring unlike humans who usually have 1-2 child, with 3-4 or more being less common. Granted I did forget to point to Ellri that animals like dogs and cats, among others, why animals didn't have  actual 'breasts' due to their barrel like chest and the fact they run on all fours. It would end up hindering them. 

Which now makes me consider that might be a problem with Angie, Ellri, when she is able to go on four legs and flat out run. Even with the extended torso. As for Roan's... anatomy, it's is more canine in that area as well due to some choice words an artist made in a digitgrade tutorial including the sound reason: '... crushing your nuts on the hunt isn't fun...' I think most our male Players will likely agree with that. XD *prays she doesn't get banned for the terrible joke* 

Mostly, while I think Ellri could've left out the detail in my opinion, he means it more in scientific manner than anything sexual Free. One talk with him over the matter and I'm pretty sure you'll start wondering the same thing I do, if those things are [i][u]even[/u][/i] possible with him. :P
