I have often had the fantasy where I feed a reluctant skinny model, of about 100/110lbs by force until she is super sized. It usually involves her accepting her extra weight once she gets to about 170/180lbs, where she starts begging me to feed her until she gets to at least 300lbs. She realises how much sexier she is looking with every extra pound. Also her sex drive is going through the roof, as she gains, so that she gets more and more addicted to wanting to gain weight.
