Soak her T-Shirt like a wet T-Shirt contest
From Create Your Own Story
You flash your sister a wicked grin as you unleash the pressure from your balls like the firehose it is. In a matter of seconds the entire front of her shirt is covered in hot jizz and she has a huge smile plastered on her face. She speds a few moments rubbing her tits back and forth really grinding the hot cum into her skin.
She leans offer and gently kisses the tip of your, using her tongue to suck up some of the left over cum.
"See you at breakfast lil bro." She teases as she steps out of the room.
