Grownup Retailer Sex Store On-line Sex Toys\n<\/p>\n

If you already bought Le Wand, you might as properly splurge and purchase the Le Wand Silicone Attachment, too. The attachment matches on the end of the wand and transforms it right into a masturbation sleeve, so anybody with a penis can enjoy one of the best “handjob” of their life.
