Jerking Off with Futa Step-Sister

Winter is finally gone, and with it are all the conservative clothes your new stepsister, Sydney Screams, has worn. As you enjoy your morning breakfast, I walk into the kitchen wearing a low cut tank top and a short skirt... with my futanari cock hanging out! You're shocked but you don't say anything as your eyes keep glancing at her long cock. It hangs almost down to my knees. Later that day, you stand at my cracked doorway, watching as I sit in bed stroking my big dick until I catch you. You tell me that you were watching me masturbate and that it turned you on, so I invite you to join me. You can't believe your luck and rush to sit down next to me, worried that I might change my mind. I lube up my cock and hand you the lube for yourself. As we sit in my bed together, jerking off together, I pull out my big tits and encourage you to jerk off too. I want to watch how you touch yourself! You're so turned on watching your new step-sister stroke her big cock. I ask if you want to compare our cocks, placing your cock on top of mine and next to mine, stroking both of them together as we frot and make the tips of our dicks kiss. Though you may be jealous of how big my dick is compared to yours, you love the feeling of our dicks touching especially when I stroke both of them together. It's too much for me to handle too, and I start stroking faster until my futa cock explodes, cum dripping out of it as I tell you to cum too.
