What's actually going on here is that at the same time Nozomi has increasingly racy IV (gravure) releases, a girl from the same stable as her - who shares more than a passing resemblance, is going full AV (adult). So while Nozomi is doing anything as much as a handjob (also footjob if you check out the earlier posts on the site), her coworker Miku Sakurai (pictured) is the one going full-adult with blowjobs and penetration.
To be honest, I'm happiest with Nozomi exactly where she is. I love the incredibly racy gravure she does without being "tainted" by some dude. Not that there's anything wrong with being fucked, but sometimes they go with gross guys in some sorta fetish flick and it kinda ruins it for me, y'know? More importantly though, with simulated sex scenes using dildos etc, Nozomi can actually show us a lot more of what's going on down there - due to Japan's odd laws about what should and shouldn't be pixelated, and to what degree.
EDIT: Hmmm... I'd never bothered to read the blurb under the title cover until now, and it indeed appears she may be doing AV after all? To whit:
そして遂にアダルトレーベル、メディアネクサスに高田のぞみ嬢もついに参戦!
And in a turn-about/backflip/complete reversal, Nozomi Takada will also be taking up the challenge for the Media Nexus adult label!
現在、AV未満での活躍モデルがKINGの指導の元ポルノの世界へ。時代はのぞみ嬢に抜かれる時が来た!
The time (era) has come for Nozomi - who until now had only appeared in "less than full porno" titles, to finally take over!
My, my, my. What a wonderful age we live in!
