It's a long week

You keep thinking about Lucy, and everything you've done with her, and everything you want to do. It's hard to keep it out if your head, and you have almost a constant erection, one that you can't get rid of the normal way. You resist for one day, two days, three days. But on Wednesday it's almost too much. You spend all evening looking through Lucy's instagram photos, looking to see her out on the town in skimpy clothes, or in a bikini. You can hardly believe that you have got to see the body behind those clothes. A few times you accidentally "like" some of the photos; you try to undo them as quickly as you can at first, but then you realize that it's probably fine: from what she said, Lucy is probably a little excited by this softly pathetic display of devotion, so you start openly "like"ing the sexier photos.

So far you have resisted jerking off, but after a while you reflexively stroke your cock a few times. You stop yourself, but after a few minutes, start to think the obvious question: how could Lucy even know? You push it out of mind, not wanting to ruin the good thing you have going with Lucy by ignoring her rules, but the temptation keeps coming back.
