full obtuse

Engaged in the doggy style position on a posture pedic bed. The guy starts raising the bed with the remote driving her head into the mattress that is raising. This creates an obtuse angle with the bed and the doggy atyle becomes an obtuse angle because he is pushing her head into the raising part of the bed.

We snuck into an empty room at the hospital and I raised the bed and went full obtuse on that nurse.
