Good

You sheepishly bow your head and say, "Surprisingly okay."

Katrina giggles, then kisses you on the cheek, "I had a feeling you'd like it. You'll like it even more when it's not your own though."

Your sister pulls out her phone, takes a picture of you, then looks at the time before saying, "It's getting late, we should let the sissy get to bed, afterall she's got a long day ahead of her tomorrow." Amanda flashes you a wicked grin.

You're too exhausted to even get upset over her taking your picture, so you just stumble to bed and fall asleep, the taste of your cum still on your tongue.
