"Make It Hard"
This story is quite recent since it happened just a few months ago. My slightly older sister came for a visit to our house and had the idea of shooting me and my husband naked since we hadn't done it for a long time. I know that my husband enjoys being naked around her since she has an amazing body and they really love each other. This time though he was a bit nervous so his penis was flaccid.
In order to help him show his best potential, I rubbed my knees on his cock and balls during the photoshoot, as I was posing for my sister. This kind of worked since I felt his penis growing and oozing precum. When I took it off, the change was more than obvious, with a semi-erect penis appearing. It was clear that my sister noticed it because I saw a tiny laugh on her face, even though she always tries to hide those things.
My husband thanked me later, because he would be sad if his flaccid penis was the only thing on the menu.
