Boy: "Hey, I'm straight."
Futa: "You just never sucked a good girl cock. Come here."
Boy: "Anyways I only kiss my girlfriend (well, we haven't kissed yet, but still…)."
Futa: "She doesn't need to know. Let this be our little secret. Just the tip. What are you afraid of?"
Boy: "Hey…! Mmmm…."
Futa: "Just the tip. And then the whole cock."
…
Futa: "Your mouth feels so good on my cock. Straight boy mouths are the best."
…
Futa: "Oh yeah. Show me all my cum in your mouth. Now swallow it all. I want my cum inside your body."
…
Futa: "When you kiss your girlfriend, don't forget to ask her how my cum tastes on your lips."
