A cuck... Usually either a husband or boyfriend who is at first a semi sexual dominant, but when a more dominant male is present, the cuck rolls over for him. His sexual pleasure changes from actual intercourse to watching his wife/gf reach orgasms he could never give her, usually because of his inferior size or stamina or both. There is often a degree of fascination with the more sexual dominant ( bull), usually with size and performance. Sometimes a more dominant cuck will be aggressive in finding partners for his woman, simply as a way to work out his masculine urges, as he is emasculated in almost every other way. Sometimes his aggression here is truly for the love of his partner. Other cucks simply bankroll the partners pleasure, sometimes enjoying to watch or just clean up after...
