Steve and Fiona were making passionate love in Steve’s Volkswagen Kombi van when suddenly Fiona, being a bit on the kinky side, yelled out “Oh you dirty boy, whip me, whip me!!”
Steve, not wanting to pass up this unique opportunity and obviously not having any whips at hand, did however have a flash of inspiration – he opened the window, snapped the aerial off his van and proceeded to whip Fiona until they both collapsed in sadomasochistic ecstasy.
About a week later, Fiona noticed that the marks left by the whipping session were starting to fester a bit, so she went to see the doctor. The doctor took one look at the wounds and asked, “Did you get these marks having sex??”
Fiona, embarrassed to own up to having kinky sex, eventually admitted that, yes, she did.
Nodding his head knowingly, the doctor said, “I thought so, because in all my years of doctoring it’s the worse case of van aerial disease I’ve ever seen…”
