Despite definitely being old enough to know better and knowing exactly how the conversation will go because you've been down that road before, sometimes you just feel unable to summon any resistance, and find yourself completely drained of tips!
"Tip me, fag" and you tip. "Tip me another £15 so that I send you some hot pics" and you do. "I need another £9 to withdraw the tips".
You oblige, and you do get some pics, nice but more or less the same ones already on here.
"Send another £25 for some nude pictures", and you do because after all you've already 'invested' some money.
Then the "what do you have left in tips? Send everything!" comes at the same time that you're unwisely sniffing some poppers... and the rest is history: no tips left, and no dick pictures either since apparently nude means being tastefully covered by a towel.
Dick pics would mean even more tributes and by this time, luckily, you decide that it may just better to cut your losses and go to bed!
