I don't masturbate very frequently, normally about two or three times a month, but when I do I like to do it properly and get really, really horny.
In most of my sessions I start by undressing and feeling my firm breasts, pinching my nipples and stroking my slim body in front of the mirror. When I start to get really wet I sit on the side of the bath or lie on the floor and slowly tease my clit, stroking around it and brushing my fingertips across it.
I like to fantasise whilst I do this, sometimes imagining I am being forced into masturbating for someone like a kidnapper, or that I get caught by a gorgeous young girl or guy but continue just for them. My favourite fantasy involves being tied up and teased endlessly by a beautiful girl until I scream for her to finger me to orgasm and then returning the favour.
As I continue I rub my clit harder and harder as I really love the pressure, sometimes using both my first and second fingers side by side to rub as it feels really intense, until I feel myself shaking into an orgasm.
I hope this has helped a few people out with their own fantasies.
