When Kat returned, there was nothing to indicate that anything had happened between Donald and Heather, aside from their body language. Heather wouldn't take her eyes off Donald and vice versa. Kat kept wondering if anything occurred, and the more she obsessed about that idea, the more it excited her in spite of her beliefs. She hurried to her bedroom and climbed under the covers to stroke her pussy until she got relief.
Kat didn't expect Heather to walk in on her while she jilled off, but her friend was very calm and matter-of-fact about it.
"Chill, honey. You're far too uptight about it. I'm glad to see you showing an interest in these things. It's healthy, you know, to masturbate. Even for girls. We have needs, too. You should try a vibrator. It would make things so much better. You can borrow mine any time. You don't even have to wash it," Heather told a very red-faced Kat.
"But it's a sin!" Kat worried.
"I guarantee you that even nuns do it. Especially nuns, in fact. They need to jill off more than most women. You won't go to Hell for it, but if you do, I'll welcome your company," Heather flirted with her friend.
"Why am I like this all of the sudden? Heather, you're cool with things like this. You know, perverted things. Do you know why I'm excited by the idea of you and Donald having illicit sex. I keep picturing his penis in your vagina and I just now imagined that it was in mine. That's incest! Why would I think of such things? I shouldn't have those thoughts at all, let alone about my own brother!" Kat confided desperately in her friend.
"Wasn't that the real purpose to the mission you assigned me? You wanted to make sure that he wasn't gay, so you could seduce him. I was to be the bait, and yes, he took me. Don't worry. I'll share him with you. I'm not the jealous kind. Just bear in mind that now I've had him, I won't give him up. I had my own reasons for seducing Donald. My intuition told me that he'd be just right for me. It tells me also that you're more deviant than you're letting on, even now.
"There's nothing wrong with wanting to fuck your brother. In fact, there's nothing wrong with actually fucking him. He's yummy. Trust me on that point. I'll help you on the condition that you do as I say from now on. Think as me as your teacher in sexual debauchery. Lesson one. Don't call it a penis. Call it a cock or a dick. Clinical terms are so dull. Same with vaginas. Call them pussies, cunts, or twats.
"Do we have a deal, Kat? You'll do as I instruct you and agree to tell only certain trusted people. In return, I'll help you loosen up and actually enjoy yourself for a change. You could use a mentor in matters of sexuality," Heather proposed to her girlfriend.
"Oh, alright. I guess that I'll just have a lot more to confess next time around. My priest might have a stroke. So I have to do as you tell me, not get jealous about sharing Donald, and start using dirtier terms for private parts. Anything else, O Professor of Hedonism?" Kat responded with unusual wit.
"Yes, that includes sucking my pussy. Don't worry. It won't kill you to eat me out. You might even have fun with it. Here, have a taste while you stroke your clit. Push yourself down lower on the bed to give me more room to sit on your face," Heather ordered her "pupil".
Kat resumed her masturbation while Heather straddled her mouth. The smell and taste astonished Kat. She expected it to disgust her, but it was actually delicious. She liked eating pussy. Before Kat knew it, her tongue buried itself naturally between Heather's folds and tasted the rest of Donald's cum there. Being a virgin, she had no idea what she just cleaned up, but her friend was well aware that she had just given her new student her brother's creampie.
"That milky stuff inside me is Donald's cum, Kat. You just tasted your brother's spunk. How would you like him in your pussy? You wouldn't have to stroke yourself so hard to cum, I believe. Are you ready for incest, or is it too soon?" Heather dared her friend.
