[B/S] Me and my sister work in the same office, and as often as we can, we sneak off to have sex. We almost got caught this time, but that just made it so much better...
Ugh, my big sister is so gross! She waits in my bedroom for me to come home, and as soon as I open the door, she blows her load all over herself! I swear, it's almost as if she gets off to seeing my face...
"I know you're feeling better but you still need to take your medicine! Come on, your little sister is almost finished preparing it. Remember, every last drop!"
You're starting to think those hidden cameras you installed in your sister's room are no longer secret... Sometimes it seems almost too perfect, like she's putting on a show for you.
Your big sister always takes ages in the shower each morning, making you late almost daily. Finally one day you decide to interrupt her and kick her out. Ever since then, you two shower together.
