Sh*gged my Sister-in-law, wifeys twin, about 4 times over a 6 year period. Got caught on the 7th go, sober unfortunately, when wifey got back quicker than I expected from buying lottery tickets! By f*ck, the phrase "hell hath no greater fury ... etc" is 'kin' true. She went supersonic at both us, her twin sister getting the worst. Said she could have accepted if we were both legless, but at 3.00 o clock on a Saturday afternoon on the settee in daylight with the curtains open was just not on!!! Didn't tell about the other times - thought that might upset her a bit more! I was saved by a Balkans deployment and time being a great healer. Oddly enough, her sister doesn't talk to me anymore - but now I now the "real difference" between them! I suppose, lookng back, it was worth the ear bashing followed by weeks of "full picture, no sound" before the deployment.
