You have been left alone in the house for a few days with me, your step-sister. We've fooled around in the past but this time we have the house all to ourselves. You're trying to be on best behaviour since you promised our step-mom you'd be good while she's away. But when you find me in my room feeling upset because my boyfriend has let me down yet again, you start to feel tested. I am clearly vulnerable and need someone to comfort me. You feel your dick hardening in your pants when to your surprise I take the lead and ask outright if you're turned on. I waste no time revealing your cock and taking it in my mouth. I can't resist tasting you again. I know it’s wrong but I can't help myself, the chemistry between us is electric. Before I know it I'm begging for your cock inside me again. I can't help but be a total submissive slut for you opening my legs and begging for your length to fill me. You fuck me hard and intimately. It feels so good to be so close to you, your balls emptying inside my pussy as I take your load. We enjoy the cum down together before you leave then I call our step-mom to let her know you've been a bad boy... (to be continued...)
