A quiet room. A relaxing bath beforehand. Lube. More lube. Maybe a finger first. Is today the day? Two fingers. Now three. Yes, this might happen today.
Put a towel down. Get it out of the box. Put it next to you, in sight at all times.
Three still easing in. You grab a toy. Nothing special. six inches, fairly fat. the kind of thing you could risk being found without too much embarrassment. The kind of dildo your aunty has. Or your mum. Or your boss.
