Viagra, estim deepening te sulcul groove.

Estim on max, keeping the attachment wrapped half way around the glans to expose the corona and sulcul groove. I pull the shaft skin down hard, then I grip the stretched inner foreskin to stretch then skin away from the glans, tugging at the groove to lengthen and extend it downwards to try and make it deeper. One day, the skin is going to split in the groove along the feint join line.

The images show the after effects of the stretching. One part of the sulcus groove right in the middle of the dorsal side has become overstretched. The tingling sensation is incredible where the skin has been stretched.
