Once when i got a sonogram of my right leg to chwck for thrombosis (it sucks having it), the tech told me flat out "i cant work with pants...you'll habe to take them off...of course i waa freeballing like always....she was a lil shocked, but as ahe lubed my leg, the sheet she put ovwr my dick was flimsy and she xouls see my erection. I even got the sheet messy with precum...i jacked off as aoon as ahe left.
