Sirius has a quadri-polar design that makes easy work out of prostate milking. Stimulate up to four areas at once with a dual-channel stimulator, teasing deep inside your ass, tickling your perineum and massaging your prostate in unison. You can expect powerful contractions and an intense tingle that nudges Sirius against your sweet spot. The Shape and Play design allows you to angle the tip, shaft and perineum stimulator for a tailored fit against your erogenous zones. Feel the tip stroke and nudge your prostate with every pulsation, pushing your sexual satisfaction to incredible new heights.
