Cath never admitted it, but since she became obese, she noticed that when her friend Yina offered a belly massage to her fat girlfriend when she had eaten too much, she loved it, as it relieved stomach aches and helped digestion, but also noticed that it gave pleasure.
It's as if since her belly became bigger, and therefore easier to play with, that this allowed her to discover that she has a sort of orgasm if they start playing with her belly, being became more sensitive than before in the stomach area, being very ticklish since childhood.
But she had difficulty accepting this, finding it odd to get some sort of sexual pleasure from being played on her stomach, until finally agreeing to try it and asking her girlfriend to play with her stomach.
Cath is embarrassed to have her big belly played like this, she who still has difficulty has accepted her enormous body, but it is even more annoying that it is so exciting and tries to hide it from her girlfriend, but has hard to hide that, being too good.
