My twin sister called me one night to complain about her husband's cock. Apparently he has a curve to the side that makes sex kind of uncomfortable and blowjobs near impossible. She was really distraught until I told her that my husband has a downward curve to his circumcised cock. She said that the downward curve is great for deep throating. I had no idea what she meant. So she told me that she could come over and show me. Man, my sister sure knows how to suck cock. I'd never heard of deepthroating. Let alone trying it. But I learned a thing or two from my sis.
