I just saw a Japanese video that actually did this idea! It's called 24 Hours of Semen #2. Video is available from
www.japansm.com, and the link is:

Basically, the video is Riho Nanase doing everyday things in an apartment while 10 - 15 men come in at certain times to blow their loads on her (even on the way out to go grocery shopping

.
Anyway, for the Bukkake phone call, she is on the cell phone with another lady and you can hear the conversation (I wish I knew Japanese). I wonder if it was Mom too. Anyway, while she is carrying on the conversation, the men jack off all over her, and she moans a little. She has to repeat what she says a few times because she is amassing quite a hefty load of cum in her mouth. You can tell the other lady on the phone is wondering what is happening. Very hot scene and I hope JM Production does there own version. Maybe bring Crystal Ray out of retirement since she is a chatterbox, heh.
