Rechargeable Power Stud Over and Under Dual Penetration Dildo is a dual-shaft vibrator designed for simultaneous vaginal and anal stimulation. The larger shaft measures 5.5 inches long with 1.75-inch width, while the smaller shaft reaches 3.5 inches with 1-inch width. It delivers 12 vibration functions, USB recharges in 90 minutes for 60-minute sessions, and remains fully waterproof. This product suits people seeking double penetration sensations with customizable intensity control.
The Power Stud Over and Under delivers vibration through both shafts simultaneously, allowing the larger shaft to stimulate the vagina while the smaller shaft targets the anus at the same time. The dual design rotates power to both penetration points equally, creating layered sensation that single-shaft vibrators cannot replicate. The 12 vibration functions range from gentle pulses to intense rhythmic patterns, letting you adjust intensity without stopping to change products.
Body-safe, phthalate-free PVC forms the main shaft construction, while the control button uses smooth silicone and the charging cap features durable ABS plastic. This material combination resists degradation through repeated use and extended water exposure. Those seeking additional options can find our pulsators collection at Adultsmart.

Pairing the Power Stud Over and Under with a rotating clit stimulator creates layered sensation across multiple erogenous zones simultaneously. Many people find that external clitoral stimulation combined with dual internal penetration intensifies arousal and extends pleasure duration. This combination approach allows for exploration of different sensation pathways that single-product use cannot achieve.
After each session, rinse both shafts under warm running water with mild soap, paying special attention to the seams where the shafts meet the base. Ensure the charging port cap remains sealed before any water contact. Allow the dildo to air-dry completely on a clean towel before storing in a cool, dry location away from direct sunlight. Store separately from other silicone products to prevent material degradation.
Body-safe phthalate-free PVC construction ensures the Rechargeable Power Stud Over and Under meets safety standards for internal use without leaching harmful chemicals. The non-porous material resists bacterial growth and maintains structural integrity through repeated use and cleaning cycles. Silicone and ABS components are hypoallergenic and compatible with water-based lubricants, making this dual penetration dildo suitable for sensitive skin and allergy-prone anatomy.
This product suits people exploring double penetration sensations for the first time or those already familiar with dual stimulation seeking customizable intensity. The dual-shaft design appeals to those interested in simultaneous vaginal and anal play, whether exploring solo or with a partner. The 12 vibration patterns accommodate various sensitivity levels, making it accessible to people with different pleasure thresholds. Its waterproof design attracts those seeking bath or shower play integration into their intimate routines.
Some people respond only to simultaneous internal stimulation at multiple points—single-shaft penetration feels incomplete because it addresses only one area while leaving the other untouched. The Power Stud Over and Under's dual-shaft design delivers vibration to both the vagina and anus at the same moment, creating a sensation pathway that works when solo penetration does not. For those frustrated by single-point products that require constant repositioning or multiple toys to achieve the sensation they seek, this integrated design shifts what feels satisfying. The independent shaft sizing acknowledges that vaginal and anal anatomy differ, so each opening receives proportionate stimulation rather than one-size-fits-all penetration. For people who have settled for sequential stimulation because simultaneous options felt too complicated or expensive, discovering that dual penetration can be accessible and straightforward changes how they approach intimate exploration. The 12 vibration patterns mean you're not locked into one sensation—you can vary intensity and rhythm within a single session without stopping to adjust settings, making pleasure feel continuous rather than interrupted.
Our independent testers evaluated the Power Stud Over and Under's dual-shaft stability, vibration transmission consistency across both penetration points, and control responsiveness during extended sessions. The testers confirmed that vibrations reach both shafts equally, with no dead zones or reduced intensity at the connection point. The button activation responded reliably across all 12 patterns without stuttering or unexpected function skipping.
Testers reported that the shaft proportions accommodated varied anatomy without requiring uncomfortable stretching or forcing, and the waterproof seal remained intact through multiple aquatic sessions without water entering the battery compartment. The 60-minute runtime extended through typical extended-use sessions without power loss affecting vibration intensity. Individual results may vary based on anatomy, sensitivity, and usage.
