Deep Sea Double 

When a woman is vaginally penetrated, in an aggressive manner, by two penises at the same time. Similar to a vaginal Parkering. It is distinguishable from double vaginal by the aggressive manner in which it is performed.

Kyle and I met this hot chick at the bar, went back to her place and gave her a Deep Sea Double.
