#4, photo 2 looks like a younger version of my now ex-wife. From the age of 34 till she was 45, she was enjoying sex with other men including 3 lads in their 20s, two of my ex-work colleagues and her mate's step-dad, all with my encouragement and approval. Never went black though as far as I know. Came close though, kissing a black guy passionately in a club on a girls's night out, tongues in each other's mouths, and let him put his hand under the hem of her short skirt to massage her bare thigh.
