Enhancing The Harness Play
People cannot live by inspiration alone; the same applies for the harness wearer—he or she needs more than mental stimulation alone to cum. This explains why harness-wearers frequently ask how they can stimulate themselves while penetrating their partners with a dildo. Auto-stimulation while penetrating a partner is possible and in fact a surprising number of options for doing so exist.
As penetration using a dildo and dildo harness is a hands-free affair, the possibility of using your own hands to stimulate your genitals or anus is apparent especially if you are using a two strap style harness or a one strap style harness that has an opening for genital access. If your hands do not provide enough masturbatory intensity, you can always use a bullet or egg remote controlled vibrator sex toy against your clitoris or perineum. Another option for the vibrator is to place the sex toy between the dildo and the wearer's genitalia so that the vibrations travel along the dildo into the person being penetrated while stimulating the genitalia of the dildo harness wearer. The MSX Silver Bullet Sex Controller is a perfect option for this type of auto-stimulation. The sexperts at Good Vibrations.com suggest that "small battery vibrators offer the best way for harness-wearers to get clitoral stimulation. Vibrating dildos transmit vibrations beautifully to both the harness-wearer and her partner. Some women obtain clitoral stimulation by tucking a vibrating cock ring around the base of the dildo between flesh and harness, while others substitute a vibrating-egg vibrator. As long as the vibrating sex toy model produces the desired vibrations and takes minimal effort to keep in place, it doesn't matter which one you choose.
Those who crave vaginal penetration can purchase a double harness, like the Doc Johnson Vac-U-Lock 2000 which features a second hole positioned over the wearer's vagina accessible to a partner's fingers or dildo. Double harnesses are designed for use with two separate dildos, not with a double dildo. Some harnesses also feature an additional space for the use of two dildos for the dildo harness wearer so that both their anus and vagina can be filled. Another option is to use a double penetration dildo attached to the dildo harness to stimulate the dildo harness wearer.
Yet another way to turn your single harness into a double harness is to attach a harness cuff. The harness cuff is a rectangle of fabric or leather with a hole in the center and snaps or Velcro on each end which permits you to simply slip a dildo or plug through the hole in the cuff, insert the dildo or plug into your body, and fasten the cuff in place around the center strap of the harness (Ibid). Cuffs work best with single-strap harnesses, but the leg straps of a two-strap harness are adjustable to allow one to wear a cuff between the legs. As a cuff will hold the entire length of the dildo or plug inside you, you should make sure to select a comfortably short model.
