Nosy Neighbour: Lesbian BDSM Erotica

A mature lesbian couple are engaging in a particularly noisy and intense bondage session when they notice the curtains of the house next door twitching. They quickly realise that their neighbour is spying on them and decide to let her watch, turned on by the idea of her spying on them. However, when they hear a knock at the door, their night time activities become much more interesting.
