mrs P. and i are overweight. badly overweight. much moreso than your wife. our first party was almost cancelled because we were so self concious...
we have not been to a party where we haven't been "cornered" by a couple
it is quite flattering. many of the parties Mrs P has caught the attention of the most attractive guy at the party, and kept him captivated. the reasons are simple... tits, arse, curves, personality, open and excited about sex. even some of the "stick figure" girls at these parties are openly jealous of some of her curves...
we even had one couple recognise our online profile from her cleavage
on the other note. yes her metabolism should rise as her body comes out of starvation mode, but the biggest adjustment she will need to make is portion size. she has gotten used to eating more, and gaining no weight due to her medical condition. she needs to "re-learn" her eating habits now that she is going to be absorbing EVERY calorie in her food.
