Yes

Lisa lets you go for a moment to take a breath, and then, this time on your own, you go back to a task at hand (or at tongue to be specific). You are beginning to like it, she tastes really sweet and it feels good to make her feel pleasure. You feel that you yourself are getting excited. She is moaning really loud, you wonder if your parents heard this. Not that they will have anything against it, they'd prefer you to be in a stable relationship, but they also believe that you have to make your own choices. And now your choice is to lick Lisa's pussy.

She is really close to orgasm, you can feel it, so you double your efforts, your tongue makes circles around her clit and soon you are rewarded with Lisa's loud scream and her squirt covering your face and and her body is shaking from the pleasure you gave her. You look at your friend, still covered in her juices, and see her flushed, happy face.

“That was amazing” she whispers. And you feel like you are in love.
