She starts to lick the tip, you can tell she doesn't really know what to do but you see how excited shes getting. Putting in more effort she starts to go deeper fully swallowing your cock. Since shes not use to being throat fucked you almost make her Yak... your little sister wines out to be careful. Hungry for more she goes back, starting to gag even harder on your cock she feels you throbbing inside her " I want you to cum in my mouth, I want to taste Cum for the first time" you fill up her mouth with thick cum and it drips down out of her mouth "please don't tell mommy she already thinks I'm a slut"
