The missus and I got a Liberator ramp/wedge combo and got to break it in not too long ago. It was a lot of fun getting to try all of the suggested positions and find what worked for us. However this is a different story. More recently, we did something with the new furniture that neither of us had planned or even anticipated.
After getting to try out the wedge/ramp only days earlier, we were looking forward to getting to fully utilize it so when the time came we quickly stripped down and positions ourselves. As I am incredibly fond of giving her oral, I was ready to lay her down with her knees arched and press my lips around her clit. The missus had other plans.
She pushed my back against the ramp, my head on the upper edge. She slid the wedge under my knees. My ass was on the ground between the two pieces and my wife took my cock in her hand and began to massage it. As she stroked, her grip tight and her pace slow, her lips kissed my inner thigh. A twinge of pain hit as her teeth dug in occasionally. My dick became ever more erect as her cheek and her hair brushed against my shaft, her mouth avoiding it completely.
