I was sitting on replying to this but I think I'm going to chime in here.

Firstly, it sounds like you had a pretty crap experience, which sucks considering how expensive punting is, but I had an entirely different experience and want to address some of the differences.

I will preface this by saying that I have only seen Sayaka in a lesbian double with Yuumi when she was still around so I have no experience with her in a 1 on 1 session. I also paid extra to film and am watching the footage back as I'm writing this post.

Looks / Body - I can definitely see where you're coming from. She is a bit fat for my taste normally but her face isn't that box-y IMO. Is she a stunner? Not to me but she is at least average in the face department with nice eyes. For reference my ideal body type is Kiko or Anna (wish they were still around), which 42 and N5 would probably list as 160-165cm and 40-45 kg.

BBBJ - she was more into it in my session so I found her BBBJ decent and slightly above average (7/10 if I'm rating 5 as average). I've definitely had worse experiences. She used her tongue a bit and played with my balls which was nice. She was more on the sloppy side but not toothy and decent suction overall.

DFK - in my double Yuumi was more of the kisser but Sayaka did more than just lip kissing. She used her tongue a bit but I wouldn't say this is her strong suit.

Pussy - When reviewing my footage she wasn't as hairy as you described. So unless she's done nothing to maintain herself then I find it hard to believe she's let it go that wild. When I saw her it was neatly trimmed and didn't see a trail towards her ass and wouldn't say it went as high as her belly.

Sex - sounds like your experience sucked but she definitely no starfish in my session. Was very proactive in cowgirl, was quite responsive in general, and I enjoyed her in missionary.

My overall experience was that she as a proactive, bubbly, and fun person to be with. She was also the one getting down and dirty offering to rim me (I don't like rimming personally), eating out Yuumi's pussy, etc. so I thought I found her to be the more involved person in my threesome. The entire experience including personality I would rate 7/10 however, this is based on my experience of her in a lesbian double.

The big question - would I recommend? I would definitely recommend seeing her in a line up first to see if she fits your aesthetic but I definitely had a much better experience than the OP. Also considering she is $290/hr, which for J girls at 42 is reasonable as they usually range from $280 - $350 / hour, I wouldn't label her as a waste.

Anyway this is just my experience, which was favourable, but like all punts they can go either way.
