Next week

John sat in the waiting room starring at the sexy receptionist, trying not to stroke his erection through his pants. Damn, he thought, I thought I was supposed to be getting less boners with these pills.

"John!" Doctor Valentine opened her door. "Welcome back, come on in."

John stood and walked towards her office.

"My goodness you're quite erect!" Dr. Valentine pointed at your bulge

"Holy shit" The receptionist failed to stifle a giggle.

"When's the last time you masturbated?" The doctor asked.

"Like an hour ago." John blushed as he pushed past her and into his office. John flopped down on the couch.

"No need to be embarrassed. Actually I'm glad you have an erection, there's an exercise I've been thinking might be good for you."
