I'm going to give my exeperiences with seekingarrangement. Admittedly a few years ago and last few times i went on it seemed to have gone downhill in terms of selection. Any questions, feel free to ask.
Most serious arrangement. Sexy Maori girl in her 20s. Saw her for around a year. PPM. probably gave her 15k or so over that time. awesome sex, gorgeous pussy. solo mum but in fantasic shape. 300-500 but we could spend all day fucking some days. just ran it's course.
Other arrangements:
Sexy little north shore euro blondie - 19 with daddy issues. Parents are loaded but was still skanking it around on here. Sex wasn't the best but made up for it on the fact she was sexy. $300 but didn't really want to root more than once.
Cute Mt Wellington euro mummy. early 30s. good sex but bit of a weird thrusting action. saw her a few times. was just easy fucking and pretty much keen at most times providing kid was asleep or at school. $300 could root her as much as i wanted a time.
Older lady near botany. had had 4 kids (who had left home) and very loose. was hard to cum she was so loose. only saw her once - $300. she was keen for more but i was not that keen.
another 30s solo mum. Bit trashy. Fucked her three times in like 1.5 hours. was ok but didn't go back as just not hot enough for the $400. was too into sex toys.
Ex sensual massage cook island girl. 20 y/o solo mummy. Finger banged her but she got me horny as fuck. was keen to see her again but think she gave up.
Had some other stuff arounds. one uptight girl around 30 who wanted 750 or some shit a meet. was sexy but she didn't really want to do it so it never happened. funny thing is i saw she popped back up on there recently wasting people's time no doubt.
except for that north shore girl, the only genuine ones were sold mums who wanted the cash for legit reasons.
lots of super sexy girls wanting crazy money and not really wanting to bang who you could waste a lot of time and money on though.
The thing about many of them being or becoming escorts is true though. other girls i've met and given cash to for sex have popped up at various brothels.
