Hey Jill,
Nice concept for a website -- wife making her husband repeatedly cum without reaching orgasm.
I would suggest branching out a bit -- rather than just doing vids of you teasing him, I would do some other vids of him fucking you and then him pulling out at the last second (imminent ejaculation), shooting hands-free all over your body and face, then fucking you some more and repeating the process several times. The idea is, you "trained" him in the teasing vids, and then he puts his training to work when he fucks you, where he can cum several times and show off how many times he can cum on you without needing a break.
