B-Vibe Expand Plug

The b-Vibe Expand Plug is a rechargeable, remote-controlled anal plug that combines two distinct pleasure systems in a single body-safe silicone toy. Its expanding inner shaft cycles through three width settings — 1.67 inches (4.25 cm), 1.75 inches (4.47 cm), and 1.80 inches (4.6 cm) — so you can feel gradual, controlled fullness without committing to a fixed size. A vibrating external motor sits against the perianal zone and perineum, sending stimulation outward while the shaft targets the prostate internally. Five expansion modes let you hold at any stage, step through sizes automatically with a one-second pause at each, or cycle continuously from small to large on repeat. Once inserted and seated, the plug stays in place hands-free, and both the onboard button and the included one-touch wireless remote give full command of vibration and expansion from up to 30 feet away. The toy is splashproof, USB-rechargeable, and shaped with a 4.13-inch insertable length, a widest insertable diameter of 1.5 inches, a slim 0.87-inch neck for secure retention, and a wide 4.37-inch base with a 1.6-inch width that prevents over-insertion.

Intensity & Experience Level

Level: Intermediate — Sensation: Expansive pressure with external vibration

The b-Vibe Expand Plug is forgiving enough for anyone comfortable with regular anal plug use, but the expanding mechanism adds a dimension that rewards patience and gradual exploration. Those entirely new to anal play should warm up with smaller toys before progressing to the automated expansion modes.

Who is this product for?

• Anal explorers: People ready to move beyond static plugs and experiment with gradual, dynamic internal expansion for deeper satisfaction.
• Prostate pleasure seekers: Anyone wanting simultaneous internal prostate targeting and external perianal vibration in a hands-free format.
• Couples exploring power play: Partners who want the excitement of remote-controlled stimulation, with one person holding wireless command from across the room or across the bed.
• Users with reduced sensitivity: Those who benefit from expanding pressure and strong external vibration to experience pleasure through anal and prostate stimulation.
• People with mobility considerations: After the initial insertion and setup, the plug operates entirely hands-free, making it accessible for users who find sustained manual control difficult.

How to use the b-Vibe Expand Plug?

1. Charge fully: Connect the plug to a power source via the included USB charging cable and wait until the indicator light confirms a full charge before your first session.
2. Warm up: If you are newer to anal play, begin with external massage or a smaller plug to relax the muscles and increase comfort before introducing the Expand Plug.
3. Apply lubricant generously: Coat both the plug and your body with a water-based lubricant. Because the shaft expands during use, generous and reapplied lubrication is especially important here to reduce friction throughout the session.
4. Insert slowly: Power the plug on via the button or remote, then guide the relaxed shaft gently into the anus, easing it in until the base sits comfortably against the body.
5. Comfort checkpoint: Pause once the base is seated and confirm comfort before activating any expansion. Start in Mode 1 (Small) and allow your body time to adjust before stepping up to Medium or Large.
6. Explore expansion and vibration: Use the onboard button or the wireless remote to cycle through modes at your own pace. The remote works up to 30 feet away, so a partner can control the session from anywhere in the room.
7. Stop and release: To remove, return the shaft to its lowest expansion mode first, then gently and slowly withdraw the plug. Do not pull abruptly while the shaft is expanded.

Techniques & ways to play

• Solo gradual exploration: Familiarise yourself with all five expansion modes alone before partnered play — knowing exactly how each mode feels builds confidence and makes it easier to communicate preferences.
• Solo hands-free session: Sit on a pillow or wedge to assist insertion and let gravity keep the plug in place, then use the remote to control expansion and vibration without reaching back.
• Partnered doggy style: The partner behind has a clear view of the base and can use the remote to control expansion gradually, adding an element of anticipation and shared sensation.
• Partnered missionary: Allows full eye contact while one partner operates the remote, creating an intimate feedback loop between expansion cues and reaction.
• Dom/sub dynamic: The wireless remote naturally places control in the Dom's hands — the sub wears the plug and the Dom dictates when and how far the shaft expands. Establish clear signals or a safe word before handing over remote control, and agree on limits for each expansion mode in advance.

Pairs well with / Complete the scene

• Water-based lubricant: Required for safe use with silicone — reapply throughout play, especially as the shaft expands.
• Warming lube: Enhances the sensation of gradual expansion for temperature play layered on top of the vibration.
• Smaller anal plugs or trainers: Ideal warm-up tools from the b-Vibe collection for users building toward the Expand Plug.
• Prostate massagers: Complement the external vibration motor for users who want to layer internal and external prostate stimulation across a scene.
• Restraints or blindfolds: Heighten the remote-control power-play dynamic by limiting the wearer's ability to intervene, deepening the Dom/sub experience.
• b-Vibe anal play collection: Explore the full b-Vibe range for compatible accessories, cleaning solutions, and graduated toys designed around the same body-safe silicone standard.

How to clean and care

Cleaning: Wash the plug before and after every use with warm water and mild soap or a dedicated toy cleaner. Pay particular attention to the grooves around the expanding mechanism and any seams where residue can collect.

Drying: Pat the surface dry with a clean towel or lint-free cloth, then leave the plug to air-dry completely before storing.

Lubricant compatibility: Use only water-based lubricants. Silicone-based lubricants can degrade the silicone surface over time and should be avoided.

Storage: Store in a lint-free bag or dedicated box in a cool, dry place. Keep the plug separate from toys made of different materials to prevent chemical reactions between surfaces. Store in its lowest (smallest) expansion mode and in a padded pouch or separate compartment to protect the expanding mechanism from damage.

Additional information

The b-Vibe Expand Plug is designed for both solo and partnered use and can stimulate the prostate (P-spot), perineum, and perianal zone simultaneously. The anal-safe base prevents over-insertion, and the splashproof rating adds durability during use without requiring full submersion for cleaning. The expanding mechanism is suitable for users who experience decreased or reduced genital sensation, as anal and prostate stimulation can still produce significant pleasure and orgasm independent of genital response. After initial setup, completely hands-free operation makes the toy accessible for users with mobility limitations who may find sustained manual engagement difficult. The toy is versatile across positions and play styles, functioning equally well as a solo device or as part of a remote-controlled couple or power-exchange scenario.

Special considerations / warnings

• Mobility requirements: Insertion requires hand dexterity and some torso mobility. Using the remote also requires hand dexterity. Users who need assistance with charging or with replacing batteries in the remote should arrange support before play begins.
• Expansion caution: Never attempt to remove the plug while the shaft is expanded to a larger mode — return to Mode 1 (Small) before withdrawal to avoid discomfort or injury.
• Lubrication is non-optional: The dynamic expanding shaft creates friction that still lubrication cannot fully counteract — reapply water-based lube during the session whenever movement feels resistant.
• Gradual progression: Do not begin in the largest expansion mode. Allow your body to adapt to each stage before advancing, and stop immediately if you feel sharp pain, cramping, or significant discomfort.
• Medical flag: People with existing anorectal conditions, recent anal surgery, or inflammatory bowel conditions should consult a healthcare professional before using any expanding anal device.
• Water resistance limit: The toy is splashproof, not waterproof — do not submerge it or use it in a bath or shower.
• Consent: When using the remote in a partnered or power-exchange context, agree on safe words, signals, and expansion limits before the session begins. Never activate or escalate settings without the wearer's prior consent.
