For me, the excitement of getting others to gain made it very tempting to gain a few pounds too.  At some point, I just gave into seeing what I am doing to others.  It only started with a goal of 15 lbs to see if I could handle it.  Before I knew it, I had actually put on 30 lbs.  I was shocked at how much I gained but I really liked how soft I was getting.  After 30 more lbs, I love it.  The tables were turned.
