Over Erin's 19 years, he had always had one craving that was completely unsatisfied... His sister. Carmen was a year younger than him and since he hit puberty he'd seen her in a new light, a sexier light. Once or twice things had been very close between them, but both of them both knew how much it would ruin their brother-sister relationship if either said anything, so it was always kept secret. Both acting as if nothing was ever there. These were Erin's thoughts anyway, but he had always hoped she more than just liked him.
On his 19th birthday Erin decided it was time to make a move, but despite all his hormones screaming at him he couldn't do it. He needed a plan, and knew just what he could do. Carmen was a beautiful girl, her young pert breasts being the cause of many erections on Erin's part. She was short for her age, but perfectly proportioned with an ass that could only be dreamed about. And often was for Erin. Recently she had taken to wearing rather short skirts and watching TV constantly, Erin always joined her just for the chance of a quick glance at her snatch, unfortunately she appeared to have sussed out his idea and sat facing away from him, legs crossed.
