Spread his legs and peg him hard!

Be a good boy and spread those legs open for me. I'm going to fuck you till you explode.

You tower above him and your grip around his ankles is suggestive. Slowly you open his legs wide, laying his sensitive ass bare. You command him to keep his legs wide open for you as you slowly stretch his backdoor with your strap-on. There is no way to endure this without cumming!
