I would go with......Sensual Secret Sarah in Kingston.
External Link/Members Only or
External Link/Members OnlyThe flat is a bit of a dump, and she is slightly random, but she is dirty and its a good service - full on ball sucking, rimming, slow and sloppy bj. And she takes it in trap 2. Big tits too.
Long black hair, statuesque, pouty lips, husky voice. Ticks the boxes.
Real milf material and deservedly good reviews here.
On a different tac, April in Kensington is good :
External Link/Members OnlyShe had her own AW profile until recently with a good rating (now appears to have one which is just a referral one to Sugarbabes.)
£250 an hour, so in a different bracket/market to Sarah, but she's sexy, easy going nature and offers a great service. Speaks little English mind. Does a good rim job, and a good fuck to-boot!
