Soothing Rhythmic Background Noise

I just spent an hour and a half reading with the phone to my ear, listening to boy spank himself. At first I thought this was ridiculous, but eventually I relaxed into it and really enjoyed the soothing rhythmic background noise, occasionally punctuated by sharp intakes of breath and little groans. It turns out a hair brush is most easily heard via my cell phone, and it left his bottom nice and rosy red for the pic he sent me afterward. It's unfortunate that I wasn't able to administer the spanking myself. I'm sure I would have done it a bit harder than he did, but the whole experience was a great deal more enjoyable than I'd expected. A terrific little blooper happened near the end, though. I was having him give himself some rapid fire swats with the spatula for 30 second intervals and I would tell him when time was up. The phone really did cut out about 15 seconds in! I did not hang up deliberately, weather he believes me or not! Apparently he went on for a solid 2 minutes before I called back. I can't stop giggling about it, which is probably why he doesn't believe me that it was an accident!
