My gf (Brenda) was dating this guy Jeff who was a man whore but was jealous of Brenda ever checking out a guy or dreaming of even cheating on him. I often told Brenda to ditch his ass, but given how good looking he was, Brenda was putty in his hand. Jeff was 6'4", 200 pound chiseled body and what I was told a good 7 inch cock that he knew how to use real well. Often Brenda would talk about being fucked so hard it felt she was raped.
Summer in Indianapolis is not the most comfortable, especially when you have to wear Army khakis every day. The atmosphere on the base was relaxed, no formations or duties were assigned. The NCO club was a very popular place at night, the beer was cheap, so most guys stayed on base. There were a large number of enlisted women there, but most were interested in the other women.
Catherine met Charles because of her interest in an MFM threesome. It was as simple as that. He didn't know that at first, but it soon became clear that the reason she was 'stepping out' was her long-held fantasy of being with two men. Making a connection with him or someone like him was the first step in the process.
