A spreader pant or spreader diaper can be used as part of role play in adult BDSM activities, provided that all parties involved explicitly and consensually agree to it. In such scenarios, the spreading pants or spreading diaper may serve as a tool of dominance or submission, placing the wearer in a specific position or role.

It is important that any BDSM activities are based on mutual consent, trust and respect. Before engaging in such activities, it is advisable to discuss boundaries, safety, clear communication, and contingency plans. Both parties should be aware of the risks and consequences and agree that these activities are safe and consensual. It is also important to be aware of the proper use of such tools to avoid injury or damage.
