I love to watch myself in the mirror
When I was first discovering myself sexually I loved to masturbate in front of a large wall mirror in my parents house when no one else was home. The fact that I could possibly be seen by others through the sheer curtains intensified the experience. I also used to masturbate in a hammock in our private hedged backyard in the summer. The sun on my bare body made me sooooo hot.
Nowadays I love to watch myself in the mirror when I masturbate. I especially like to do it if I think that my husband might walk in on me any moment. My bedroom has several strategically placed mirrors so I can watch myself from different angles. I begin by slowly undressing, and then use a massage oil on my vulva & clit as well as my nipples. I have rather large areola which are very sensitive (sometimes I can achieve orgasm by tweaking my nipples alone--my nipples grow quite large with stimulation). Sometimes I use a vibrator propped on a pillow if I'm in a bit of a hurry. To get myself more excited I will look at some pictures of women (although I am straight, I get turned on breasts.)
I have to go now....I am getting horny again.
