We spent the next few minutes chasing each other around on the beach having a splash fight. All talk of my untimely erection was quickly forgotten, an... we eventually settled down to dry out and warm up on the beach. Karen's tone body was driving me crazy as she laid on her towel glistening in the sun.Once we were dry, we decided to head back to my apartment. The drive back didn't take very long.

There was no.
