I actually experienced the VR collaboration with the Extreme Fellatio series, but I couldn't help feeling a sense of disappointment compared to my expectations. First, the actress's performance was monotonous, with repetitive lines like '口マンコ' that reminded me of works by a certain erotic dialogue director, undermining the immersion. I watched it seeking the unique realism of VR, and while the fellatio play did feature masterful tongue techniques licking and sucking an erect penis vigorously, the overall experience fell short. Elements like twisting with black satin gloves, sucking with 'じゅぽじゅぽ' sounds, and nipple rubbing could lead to ecstasy, and light verbal teasing added some accent. There was a final swallowing scene, but the realistic depiction of smell was a bit off-putting, and I wished for a portrayal that emphasized the irresistible rawness. The actress's somewhat horse-like face might divide opinions, but for glove fetishists, it might be worth purchasing. However, the biggest issue is the lack of VR appeal. The play content could easily stand in traditional 2D works, with insufficient immersion specific to VR. Other VR titles offer sensations like close-ups of private parts or whispers in the ear that make you feel the actress is right in front of you, but in this work, the distance in eye contact felt far, giving the impression of watching a regular video. Overall, for those who enjoy fellatio or are tired of standard productions, there are some enjoyable aspects, but if you're pursuing VR's potential, this work requires more refinement.
