My wife got interested because her friend talked to her about her black boyfriends big dick.
She (30 at the time) then got off with an older 50+ black man in a pub and they swapped numbers.
She went to his house alone one day with my blessing - it was her day off and he was unemployed at the time.
When she got back she said he was very very well hung and had fucked her very hard right from the start.
At one point he told her to get on the bed on all fours and said he was going to fuck her very hard and make her come from his dick - he pumped her hard from behind and she came.
When she got home she was a bit embarrassed and teary about it and didn't want to tell that much - I later discovered she had sent him a text that evening saying 'Thank you' and that she had 'had a really nice time' with him.
We managed to chat about it and decided to go down the cuck route otherwise she agreed she would have just ended up getting fucked on her own by black men.
