Here is my analysis leading to Palmer's no way out.
He screwed a slut once, the slut wanted more and probably given a few more sympathy rounds in the pussy. Than he wanted to stop after tasting a used pussy. Unlike man, woman tend to have emotional attachement after a first play. Based on Palmer's status in parliament, he probably wanted to stop because the stake is too high to coninue playing and yielding to the woman. The woman probably wanted more, money or sex, whichever reward would put Palmer's in difficult position. She stomped louder than Tin Pei Lin's feet and probably whined even louder because her pussy needs more scratching by this unwilling man...and eventually, after weighing the pro and cons and the power of the internet, Palmer decided it is wise to come clean by first approaching Teo Chee Bye for help. It took days for Teo to deliberate and think how he could caliberate the news so as not to appear serious.....the rest became history...or not.
