b.cush Dildo Base

The b.cush is a dildo base stimulation cushion designed to do two jobs at once: protect the wearer from pubic bruising during thrust-heavy play and deliver pleasurable grinding sensation right where it counts. Made from super soft, squishy body-safe silicone, it has a cushy, flesh-like feel on the curved side and a completely flat backside. That flat back is finished with a tacky texture that grips most standard flat dildo bases and resists slipping during motion. Simply press the dildo base onto the tacky surface, drop the whole assembly into a harness or snug underwear, and the b.cush is ready to work hands-free. It is fully waterproof and strap-on compatible, and it doubles as a soft plug base for STP devices or packer-compatible toys, making it a compact, multi-role accessory. Measuring 4 inches by 2.75 inches by 1 inch, it is slim enough to wear discreetly under tight underwear for low-key stimulation whenever you need it.

Intensity & Experience Level

Level: Beginner | Sensation: Pressure / grinding stimulation

The b.cush is one of the most forgiving accessories in the strap-on category — there are no moving parts, no complex mechanisms, and placement is intuitive even for first-time harness users. Its soft, compliant silicone is gentle on sensitive anatomy, making it equally welcoming for someone new to strap-on play and for experienced wearers who simply want more comfort and feedback during use.

Who is this product for?

• Strap-on wearers: Anyone who wants to reduce impact and add pleasurable grinding sensation to the wearer's side of penetrative play.
• Transmasc users: People seeking affirming, genital-adjacent gear for STP base use, packer support, or increased bodily connection during intimacy.
• Couples: Partners exploring new ways to share physical sensation during penetrative or grind-based play — the cushion can be flipped to stimulate a partner as well.
• Solo explorers: Anyone who wants hands-free grinding stimulation during solo sessions — just slip it into snug underwear and move.
• Extended wearers: People who wear STP devices or packers for longer periods and want to minimize pressure and fatigue.

How to use the b.cush Dildo Base?

1. Rinse first: The tacky silicone surface attracts lint during storage — give it a quick rinse and pat dry before use for a clean feel.
2. Attach the dildo: Position the flat base of your dildo onto the flat, tacky side of the b.cush and press firmly until it feels secured and centred.
3. Place in harness or underwear: Slip the entire assembly into a harness with a flat or open-front panel, or tuck it into snug-fitting underwear or a jockstrap.
4. Comfort checkpoint: Adjust the angle of the cushion so the squishy, curved side aligns against your anatomy for optimal stimulation — take a moment to confirm the fit feels comfortable and stable before play begins.
5. STP or packer use: If using with an STP device, position the b.cush as a soft buffer between the device and your body for extended-wear comfort.
6. Play: Once placed, the b.cush works hands-free — use grinding, thrusting, or friction-based motion to enjoy the sensation.
7. Stop and remove: To stop, simply lift the assembly out of the harness or underwear. There are no clasps or locks — removal is immediate at any point.

Techniques & ways to play

• Solo grinding: Tuck the b.cush into snug underwear without a dildo attached and grind against a surface or pillow to explore the best angle for your anatomy before introducing a partner.
• Warm-up ritual: Run the cushion under warm water or warm it under the covers for one to two minutes before use to soften the silicone further and enhance comfort.
• Standing doggy-style (partnered): Reduces hip pressure on the wearer while maximising grind-friendly angles for mutual stimulation during thrusting.
• Face-to-face grind (partnered): Clip into underwear and let body friction provide stimulation during a close-contact make-out or grind session — no penetration required.
• Missionary with strap-on (partnered): The cushion acts as both a buffer against pubic impact and a grind surface the wearer can rock against during penetration.
• Dom/sub dynamic: The wearer (Dom or sub) controls the angle and pressure of the cushion; agree on a signal or safeword before play so either partner can call a pause or stop comfortably at any time.
• Sensation contrast: Pair the b.cush with a firm, structured dildo — the softness of the cushion balances the rigidity of the toy for a layered tactile experience.

Pairs well with / Complete the scene

• Strap-on harness: A flat-panel or open-front harness is needed for hands-free use — look for one compatible with standard O-ring or flat-base dildos.
• Firm flat-base dildo: A structured dildo with a flat base pairs ideally with the b.cush's tacky grip surface for stability during thrusting.
• STP device or packer: The b.cush is designed to double as a base buffer for STP and packer-compatible toys for transmasc users.
• Snug underwear or jockstrap: Required for hands-free solo or discreet wear — tight-fitting underwear holds the b.cush in place without a harness.
• Water-based lubricant: A small amount on the cushion's ridge increases sensitivity without compromising the silicone.
• Toy cleaner or fragrance-free soap: A silicone-safe toy cleaner keeps the tacky surface in optimal condition between uses.

How to clean and care

• Cleaning: Wash with warm water and a fragrance-free mild soap, or use a dedicated silicone-safe toy cleaner after each use.
• Lint note: The soft, tacky silicone attracts lint and dust — rinse the surface before each use if the b.cush has been stored without a protective bag.
• Drying: Air dry completely or pat gently with a lint-free towel before storing to avoid trapping moisture.
• Lubricant compatibility: Water-based lubricants only — silicone-based lubricants can degrade and break down the silicone material over time.
• Storage: Store in a cool, dry place away from direct sunlight. Keep separate from other silicone toys to prevent potential material interaction and surface breakdown.

Additional information

• Versatility: Compatible with most standard flat-base dildos, packers, and STP devices — one accessory that spans multiple play styles and uses.
• Comfort and injury prevention: Provides meaningful padding during thrust-heavy or extended-wear sessions, reducing the risk of pubic bruising and strap-on fatigue.
• Hands-free use: Once positioned, no hands are needed — the tacky surface and snug underwear or harness hold everything in place for uninterrupted play.
• Affirming design: A genital-adjacent option for transmasc users that can increase intimacy, bodily connection, and comfort during gender-affirming activities.
• Discretion: At 1 inch thick, the b.cush is slim enough to wear discreetly under tight clothing for low-key stimulation outside the bedroom.

Special considerations / warnings

• Hand mobility: Basic hand dexterity is needed to press the dildo base onto the tacky surface and to position the assembly in a harness or underwear.
• Placement time: The tacky surface may resist quick or one-handed placement — take a moment to press and centre properly for best stability during use.
• Lint attraction: Soft silicone readily picks up fibres and dust; always rinse the surface before use if stored without a sealed bag.
• Silicone lube: Never use silicone-based lubricants — they will degrade the cushion material over time and compromise its texture and safety.
• Not a medical device: The b.cush is designed for comfort and pleasure during intimate use; it is not intended to treat, prevent, or address any medical condition.
• Toy storage: Keep away from other silicone items in storage to avoid chemical interaction between materials.
