See if your sister is awake.

You quickly throw on your pajamas and proceed to your sisters room. She is fond of teasing you lately about your near constant erections. Her attitude has changed in the last few days however and you wonder if maybe something is wrong. She always seems to zone out around you lately, you hope she isnt getting sick.

The busty brunette has always seemed very healthy... especially in the chest area. Her DD sized breasts have served as wank fodder for you as of late and you cant help but wonder how it would feel if she were to be underneath you with your rod inside her. You almost start to rub your cock at the thouht of sliding in and out of her slippery hole until you feel your release but you arent sure if anyone is about or how they would react if you were caught.
