Just found the missing part of the review, must've got lost in the ether, it was a horrific, tragic ending to the punt.
"She got on all fours, I watched from behind, masturbating, still protected out of respect but using some lube she kindly provided, she jousted herself leaning forward, arching her back facing the window. I watched, excitement mounting until she went silent after a while and her body collapsed onto the bed, the room filled with a foul stench, then I realised....she had got too close to the heater under the window....and her lips had melted, then her tits, until her whole upper body was covered in a mess of charred silicon and fillers, I left, still wearing the condom."
