I wanted to do this for a very long time and quarantaine finally let me do it. She went for a quick shower in the morning and I started scrolling through some subreddits (cumsluts, girlsfinishingthejob etc.) And when I heard her coming out of the shower I decided to keep stroking above the sheets this time. She came in and did not notice the first two seconds. When she asked me something and looked at me when I was not responding, jerking off above the sheets. She later said I was rock hard, like she never seen before. She quickly joined next to me and finished me off in a record time. This will probably not be my last time doing this haha. Everyone doubting to do this, I would say just do it and you will be rewarded.
