Cheater At A Young Age

My husband and I got married in college. We have always been happy together. Why I cheated I can’t explain. My husband’s brother is six years older than my husband. He was single and a strong built very physically fit. Before my brother-in-law got married he used me for sex relief. I’m fit and ok now but at that time I was a little chubby. I wasn’t practiced up playing off men, much less a hunk that would please any woman. The first time I was carrying small boxes at my in-laws, many people there, he came up behind me and squeezed my breast hard. I walked and put the boxes down. No one could see us but could here all but a whisper he started rubbing between my legs. We whispered to meet him in pool house in 10 minutes. Why I went out I can’t explain but he pulled down my shorts bent me over the counter. He screwed me and didn’t last long and cum inside me. I had a major orgasm also. We would have sex to often to be safe but never got caught. Most likely my two children he fathered. My brother-in-law finally got married so our flings stopped. I would be exhausted and well used after sex most of our flings. In my younger years my body could handle sex with two men. Now I’m happy with only my husband.
