MKMP-608 Review: My Step Sister Hoshino Natsuki Pins Me to The Wall with Her Big Tits and Titty Fucks Me

Hoshino Natsuki getting a titfuck cumshot in MKMP-608. 星乃夏月パイズリ挟射.

Hoshino Natsuki reminded me of just how cute she is after watching her step sister movie from OPPAI last week. And here she is again in another similar movie this time from studio Million.

In MKMP-608, she portrays a younger step sister trying to seduce her brother. The movie is split into 4 scenes, each having at least one titfuck cumshot with Scene 3 having two.

Movie Review

Scene 1 – Window Pinning Titty Fuck (TF Cum)

Image Not Found

The movie starts off with a brief narration from Natsuki about how she’s tired of all the attention she’s getting fin school due to her big tits. Her new nerdy stepbrother however initially seemed indifferent to them, so she took matters into her own hands by pushing him against the window and shoving her chest into his face.

Turns out the stoic façade was just that as he quickly succumbed with his face in her cleavage and started pitching a tent in his pants. Natsuki notices this and she whips out his erect cock and quickly titty fucks it to completion.

Nice short scene to set the tone for the movie. The thing that stood out to me was that Natsuki-chan was making way more eye contact with the camera compared to her last movie. So it had a more POV feeling which definitely enhanced the fantasy for me. Sadly the titfuck cumshot was weak where you only see a little semen forming at the tip.

Scene 2 – Bedroom Paizuri & Sex (1 TF Cum)

Image Not Found

The second scene takes place in the bedroom where the siblings were initially reading manga. Natsuki noticed her brother checking out her ass, and she gets on top of him and presses her big tits against his face. After teasing his nipples for a bit, she gets into 69 position where they eat each other before she uses that same position to get a titfuck cumshot out of him.

Natsuki sees his still-erect cock and wants him inside her next. Ignoring her brother’s weak protests, she gets back on top and rides him in cowgirl. While initially objecting to the idea of lewding his sister, he soon fell to his lust as he devours her big tits while fucking her in missionary and cumming inside her.

Tits lovers are eating good this week with not only 2 rare 69 titty fucks, but one that ends in a titfuck cumshot as well. And this finish was not bad too.

The meat lover in me was pleased to see Natsuki-chan in all her naked glory. The cowgirl segment with her double tummy flab probably turned me on more than the titty fucking itself. The visual was further enhanced by the evening light in this scene which gives her a nice golden-yellow hue.

Scene 3 – Bathroom Titty Fuck (2 TF)

The third scene sees Natsuki ambushing her brother in the shower. She briefly gives him a soap rubs with her chest before the attention turns to her big tits as she titty fucks him for 2 loads.

Definitely adding this scene to my wank library. Short and sweet with not much else foreplay, and two back-to-back titfuck cumshots. The second one was especially great where they did it without any camera cuts and the way Natsuki-chan does it without using her hands and just sliding her big tits across his dick.

Scene 4 – Bedroom Paizuri & Sex (1 TF Cum)

Image Not Found

The final scene begins with Natsuki again shoving her brother against the wall with her big tits, before transitioning to her room and she’s doing what I could best describe as an amazon titty fuck, which led to a titfuck cumshot.

The naughty devil step sister continues the action by sucking her brother’s cock to get it hard again, before getting into cowgirl position. The siblings fucked for 2 more creampies to end the scene, with some titfucking mixed in.

I would have liked if they ended the movie with a titfuck cumshot, but given what we’ve gotten thus far, I can’t complain too much. This amazon titty fuck is quite the innovative position, though not completely new to me. Whether it’s on the floor or the wall, I think they’ve done justice to the “pinned against wall” promise on the title.

We got to see all of Natsuki-chan’s fleshy goodness again here. I’ve never really paid much attention to her body and demeanor before I started watching her movies to write these. And now that I’ve seen 4hrs of her in 2 weeks, she’s definitely moved up several tiers in my mind.

Summary

In case this wasn’t clear by now, I heavily recommend this movie for fellow titty fuck maniacs. While it shared a similar theme with her OPPAI movie from last week, to me this one surpassed that in every way. The main distinction comes down to the paizuri itself that had more female-dominant positions, which also bleeds into the sibling dynamic where the sister was more controlling over the nerdy protesting brother.

I’m now seeing Hoshino Natsuki under a whole new light after the past couple weeks. Sadly as of now it doesn’t look like she has any new releases lined up for next month. They say absence makes the heart grow fonder, so I’ll have to make do by rewatching some of her older works that I’ve previously only skimmed through and hope the next time I see her it’ll be another hit.
