Preparations and investigations are made

"I kinda, might have been playing the other week...!" Andy said, looking embarrassed. We all looked at each other wondering what was gonna happen now, and what was causing this guys 'contractions'!

"Ok then!" said the doctor, "Let's take a look shall we...?!" I moved to the end of the bed to get a better view as the nurse took a bottle of what looked like lube from the desk. He opened the cap and generously squirted it around Andy's crotch. The doctor pulled on a pair of black rubber gloves nearly up to his elbows and the nurse squirted more lube into his hands.

Andy's hole was very dilated now, his contractions were coming more frequently now and every time he wanted to push Andy's anus became more and more open. "Poppers." said the doctor to the nurse, and he went over and put the small bottle under Andy's nose. "Inhale deeply please." said the nurse. As the poppers took effect Andy's head relaxed back on to the bed, the feeling sweeping through his body and down to his crotch. "That's better!" said the doctor, seeing how much more open Andy's hole was becoming and how his cock was starting to grow.

"Is there anything i can do to help?" I asked, feeling helpless in this bizarre scenario.
