She's been so stressed recently. Her job has been so demanding and you know what she's like. How focused, determined, and strong she can be. You love her for it, but perhaps she also needs to see that being a little selfish from time to time is healthy. You get up early to call in sick for her and quietly head back to the bedroom. Lifting up the covers at the foot of the bed you slowly crawl up between her legs and slide her panties to the side. You'll make her tell you what she wants, and give her what she needs.
