BOBB-438 Highlights: Marumo Rea Titty Fucking in Erotic Cosplays

Marumo Rea getting a titty fuck cumshot in BOBB-438

BOBB-438 stars Marumo Rea in a cosplay-themed busty fetish movie that is quite typical of the BoinBB style. There are 7 scenes total, with 4 of them ending in a titfuck cumshot.

Rea-chan was new to me before this, but it turns out that she was actually a former S1 idol under the name Maruishi Rea. Unfortunately I had completely forgotten about her as she got lost among their sea of big-tits rookies. This is the third film of her re-debut, the previous two which I had not watched but definitely plan to do so.

Movie Highlights

Scene 1 – Swimsuit Breastplay + Titty Fuck (1 TF Cum)

The first scene has Rea in a school swimsuit with her hands cuffed. She gets her tits licked and stimulated with vibrators, before the guy straddles them until he cums between them. Her acting was a little suspect with her looking like she’s smiling and trying not to laugh, but that could be the point of the scene so I don’t hold that against her. The titty fucking also didn’t look enjoyable with how hard the guy was pressing onto his dick, but he did give her a decent looking pearl necklace.

Scene 3 – Maid Titty Fuck + Handjob (1 TF Cum)

Scene 3 is a quick outercourse with Rea wearing a maid costume. There’s some brief tits sucking and blowjob before she titty fucks him to completion. The paizuri looked much better here than the last scene with her tits mostly wrapped around the penis, and the cumshot also had some volume.

There’s actually a second part to the scene where she gives the guy a breastfeeding handjob. They used some smart camera tricks to make it look as if she was lactating, and that I find very erotic for some reason.

Scene 4 – Nun Titty Fuck (1 TF Cum)

In Scene 4 Rea plays a nun or sister (シスター) who uses her tits to satisfy a guy so that he wouldn’t visit the brothel anymore. We get another lengthy tits sucking segment into a titty fuck to completion. Her acting was again a little too wooden and deadpan, but the paizuri was again good and the money shot was the best with 2 spurts that flew out of her cleavage.

Scene 7 – POV Deriheru Sex + Titty Fuck (1 TF Cum)

The final scene is a POV/gonzo style scene with Rea playing an escort/deliheru girl. They tried to cram a lot into 10 minutes with some nipple teasing, blowjob, intercourse to creampie AND another titty fuck to completion. Rea-chan felt a lot more charming here as she’s being her natural self. The sex part was a bit uncomfortable to watch with the whole segment being shot at a weird angle. Thankfully they fixed that for the paizuri but the cumshot here was the weakest. You’d have to really pay attention to see a bit semen coming out under her cleavage.

Summary

To me this was a very serviceable re-introduction of Marumo Rea. Personally the content was a bit unsatisfying with too much tits sucking and not enough titty fucking. But this is the standard formula for BoinBB works at this point. And with the number of titfuck cumshots here, most of them being above average I might add, us maniacs could definitely “make it work”.

Rea-chan instantly got me smitten with how strikingly similar she looks like Onosaka Yuika, especially her face when she smiles or talks. Which is interesting because both of their debut exclusive runs actually ended at the same time. Regular readers here already know how I feel about Yuika-chan, so hopefully Rea-chan is able to follow in her footsteps. And I pray that we could somehow get a collaboration between the two in the near future.
