cyber spanking

[Texguy84]

Lately I have been having cyber sessions with a lady friend of mine online, and these sessions involve her giving me spankings. She wants me to send her pictures of my ass being red from the spankings, but I can't spank myself enough to get the desired effect (As you might imagine, it's a very akward thing to try and do, and I'm concerned about injuring myself)

Is there any way to make it look as if my ass is red from a spanking for this?

Thanks in Advance.
