Large Vac-U-Lock Dildo — ULTRASKYN Hung Chocolate by Doc Johnson

Large Vac-U-Lock Dildo User Guide & Play Styles

Using this dual-density Vac-U-Lock dildo for advanced backdoor play.

ULTRASKYN Hung is designed for confident users who’ve built up to larger sizes through consistent practice. Attach it to your Vac-U-Lock harness or accessory base, secure it with the included large O-ring, and take your time warming up. The dual-density realistic feel — firm inner core, soft chocolate brown outer layer — makes extended backdoor sessions more comfortable than a rigid toy of this size would. Use only water-based lubricant to protect the ULTRASKYN material, and never skip a thorough warm-up at this girth. For a deeper look at preparation, our guide to anal sex covers everything you need before going big.

Pairing this realistic Vac-U-Lock dildo with a harness for strap-on play.

The Vac-U-Lock plug system makes this large anal dildo one of the most versatile attachments in the Doc Johnson lineup. Thread it into any compatible harness using the included large O-ring — sized specifically for Hung’s three-inch girth — for a stable, no-slip fit during partnered play. The realistic feel and sculpted detail add to the experience for both partners. Because of the advanced size, communication and slow progression matter more here than with smaller attachments.
