Alex goes down on Kara, expertly kissing and licking her super-pussy for the next twenty-five minutes. Kara has an almighty super-orgasm. "Holy shit," cusses Kara, panting, "that was fucking amazing, Alex." She looks red and flustered. "I love you, sis."
"I love you too," says Alex. "And man, did your pussy taste sweet."
"Thanks. Now you have to let me return the favor."
"Only if you're sure you want to... Wait, it's safe right?"
"Yeah. It's only penetration that's really risky."
"So if you can safely give and receive hand jobs and blow jobs... why don't you?"
"I used to, Alex. Through high school and college I blew quite a few guys and some ate my pussy out too. But I had to give it up... because I knew I could never let things get any further. I could never let them screw me. So I was getting a reputation as a sort of cock-tease from hell. Everyone thought I was this awful bitch. Of course now my reputation is as a frigid ice queen instead and it sucks nearly as bad."
Alex nods. "All right. Enough talk, dammit. Eat my pussy already."
Kara gets to work, and soon Alex is writhing and shouting "holy shit!" at the top of her voice.
Eventually Kara stops. "I better give you a rest. With my powers I don't get tired, but if I carry on any longer your pussy's gonna be sore as hell."
"I don't give a rat's ass," says Alex, "I'm in heaven. Just carry on doing what you're doing." But she is exhausted and soon falls asleep. Next morning she awakes in Kara's loving arms.
