My Brother the local Romeo

My brother is the strong silence type you hear about and seldom meet. He's built as they say and 6'2" doesn't work out at gyms, his work keeps him very fit. He a year and 10 months younger than me and seemed to not to date at all, but I wasn't keeping a real close eye on his social life. But earlier this year I found out he had gotten a woman 21 pregnant; he was happy with the news, and I expected him to marry her. But it was more complicated than I first knew, yes, he had gotten her pregnant. Plus getting pregnant, her sister 18 and divorced mother 38 and was having relationship with some other women as well, luckily none of them as yet pregnant. I thought my brother wasn't into dating and I was right, he's just into bedding them. Lucky, he has a great paying job and his own home which he's paying off. By mutual agreement he is married the older daughter, and the mother and other sister will live with him. As far as I know he isn't still fucking the other women, but I haven't asked, nor has he said. He must have some special charm that stops women from hating him for playing around with other women while he is with them. His wife is okay with sharing him with her sister and mother, but whether she knows of the others I don't know. He must be a real Romeo.
