Sex Shop XXX is a network of stores for adults located in San Andreas. There are four shops in Las Venturas, and another one in Temple, Los Santos. The only enterable shop is in The Strip, Las Venturas. The player cannot buy anything from that store, however, in the mission Key to Her Heart, where the player has to follow Millie Perkins to her house in Prickle Pine, the player is required to enter the store and put on a 'gimp suit'. The enterable shop in Las Venturas contains various items, including Lightsaber Sex Toys and adult films, some starring Candy Suxxx as well as videos such as Granny Grabber 10, Return of the Anaconda, Vinewood Call Girls, and That Can't Be Legal.
In the sex shops, on the counter is a stack of films which say "Grand Theft Auto: Vice City" on them.
