Life of a 13 year old- Follow your sister into the shower
You walk yourself to the bathroom just in time as your sister turn on the shower. The silhouette on her lithe, curvy body turns you on. With one hand massaging your cock, you pull back the curtains revealing your smoking hot, freshly fucked sister rubbing her body all over.
You step behind her and start washing her back. You glance downwards, and notice the large amount of cum sticking on her inner thighs. A thin stream of cum is still dripping from her cunt, making a puddle on the shower floor. You reach your hands around her back, and start rubbing the insides of her thighs from the front in an effort to remove the caked splooge. She presses her butt into your crotch and rubs up and down, enveloping your cock between her 2 cheeks.
She turns her head around and whispers into your ear, "Fuck my ass". She takes you in a deep kiss, causing your dick to swell.
