This involves a female character using a harness with a dildo attachment to have sex with another female character. The strap-on may be referred to as the character's cock or dick or penis, it could be called a strap, or it could be referred to as a dildo. Prior to penetrating the female character's pussy the toy will always have lube applied to it and smeared over the surface of the dildo. If the toy is to be inserted into a character's ass, then a condom should be worn on the dildo and lube applied, or alternatively a lubed condom can be worn on the dildo. The appearance of the dildo should be described. Is it a realistic shaped dildo that's an imitation of a human penis, is it a realistic colour, is it any colour at all like blue, is it a fantasy shaped dildo like those available from Bad Dragon with knots or bulges? The size of it should be described, is it a comfortable size for vaginal penetration such as four inches long and an inch or two in diameter, or is it an intimidating size that will stretch the pussy to the limit? There should be nothing exceeding eight inches long as that is unrealistic for most people to enjoyable take in the pussy. If the toy is to be used for anal penetration then a slimmer and shorter toy is generally used compared to the pussy as it can be an orifice with less room to stretch. No dildo exceeding six inches in length should be used for anal sex. When the toy enters the female character's pussy or ass, there should be detailed descriptions on how the strap-on feels. Is there a painful stretch and they need some time to adjust, is it a comfortable fullness, is there a sense if relief when the strap-on is slipped inside of them, is the dildo too small and unsatisfying or maybe their desperate to just be fucked hard? With anal sex, the strap-on should always be slowly eased in for the first round if sex so that no inury occurs, unless that character had been wearing a butt plug and is already stretched. If the character with the strap-on shoves the dildo in without stretching the other character then pain and discomfort will occur but it may fade, if they want to have rough punishing sex. The character being fucked should also feel the texture of the strap-on inside them. The strap-on should be heavily described in terms of it's texture. Is the dildo smooth and gliding in and out of their hole with ease, is the dildo ribbed or textured and how does that sensation feel in their pussy or ass? If there are ridges or bumps or grooves on the dildo it will provide friction or stimulation to the character's inner walls, so is a pleasant sensesaton or is it too overstimulating? If the dildo is textured it can also pull on the openings of the character making for an erotic sight to the character wearing the dildo as it appears the anus or labia are clinging to the strap-on and wanting to hold on to the strap-on.
