The Twinfinity Lip series adds Rush — a barrage of varied bumps and ridges that knocks you out before you know it. It teases you high from start to finish. Soft front: relentlessly torments the rim, pushing, pulling and pressing; hard rear: aggressive bumps attack the shaft and tip from every direction. Two-layer dual-firmness build. Non-penetrating, mini lotion included.

What Japanese reviewers say

Based on a hands-on review by an independent Japanese review site · 2026

9/10Highly recommended · staff hands-on review

✓High stimulation from the first stroke — a barrage of varied bumps and ridges.
✓Clearly-felt frenulum stimulation — reviewers said the blowjob-style under-tip stimulation is unmistakable.
✓Recommended to almost everyone — rated 9/10 as a broadly-appealing pick.

Scored 9/10, with the relentless, varied texture and the distinct frenulum (under-tip) stimulation as the main reasons it lands. The two-layer build keeps it intense without being one-note.

Best forBuyers who want a high-stimulation, textured hole and don’t mind a more aggressive feel.
