You've been here long enough to know some detail of what actually happened needs to be included for this to remain as a review.
If you add the detail as a post I'll edit it into your OP.
I turned up at the agreed time, but she wasn't ready. As I thought she was a newbie I gave her the benefit of doubt and waited 15 minutes for her to get ready. She gave me directions to the venue.
I arrived at venue and door was unlocked as she told me. I showed myself in and sat in lounge. No sign of SP. SP comes down the stairs naked still drying herself off from bath or shower. She's larger than the size 10 on her profile, which isn't an immediate problem. I hear noise from upstairs of someone having a bath. Seemed odd. SP asked for money. I handed over the fee. SP continues drying herself off. I sit and wait for her to get ready. She announces we're doing it here on the sofa. I strip off. Noise continues from upstairs. SP makes no attempt to get me hard and attempts to apply condom to my soft cock. SP then sucks away at cock and nothing happens. I'm left on sofa thinking what the actual fuck is happening here. SP returns and wonders why I'm not hard. I ask SP to lie back so I can do RO. SP lies back watching TV and singing along to music on it while I am trying to get turned on. It's not happening. SP asks if he's hard enough yet. I have a semi. I am thinking OMG! We are about 10 minutes in. SP announces we are going to have to move things on a bit. SP has another go at OW and I have a semi. SP attempts cowgirl. I am not hard enough for penetration. I suggest RO again. SP lies back and thinks of anything but turning me on. I have a semi. I attempt missionary while she watches TV. I'm not hard enough. I suggest kissing and we kiss but no contact with lips, so non-kissing kissing. I'm not getting hard. I'm sat on sofa thinking what else can go wrong? SP return and has another go at OW. I decide this isn't happening and get dressed. SP apologies for shitshow of booking. SP is still naked. I make my way to hallway. SP closes lounge door and I am left in hallway on my own thinking thank fuck for that and should I ask for some money back?
I let myself out relieved to be out of the venue.
SP made £140 for 20 minutes with about 5 minutes of contact.
That was disappointing.

And that's why they call it punting. I took a punt and got a shitshow.
