Yui Aihara from INSERT's Maid series.

She's got a ridiculously hot bimbo body topped off with the head of an angel, an absolutely great happy attitude with just a hint of playful teasing, a willingness to do whatever it takes to please her boyfriend, plus she genuinely loves serving as a cum dump for other dudes so he can watch instead of reluctantly enduring it or leaving him for a bigger dick, as so many other hentai girls in her position do.

She is the perfect NTS waifu.
