Netorare: Tanabe Yuuka no Dokuhaku

Women in both series have sex forced upon them by a man who's not their husband and end up wanting more. 

Both titles are classed as NTR or Netorare(Cuckold) which is a sub-genre in hentai and delves into the betrayal from the main leads partner. So for those unprepared, be warned that each title will usually get a rise out of you(and not the good type from down there) as in most cases, its usually in the form of the girl having sex with someone else whilst her partner watches defenseless all due to his own insecurities. If this is your fetish then I can guarantee that both titles will aim to please. For more info on these type of hentai, visit The Netorare Club here in MAL. read more
