An unbearable burst of pain hits your entire body as her mammoth foot crushes you into nothing. The pain is shockingly real for being a simple dream; so real, in fact, that you finally pull yourself out of your slumber, awakening with bloodcurdling shriek. Sweat drips from your brow as you sit up, trying to regain composure after that horrible nightmare. It is then that you notice your little sister Amy. She's sitting casually at the end of your bed, staring at you with a smile.
"Havin' a bad dream there, Adam?" she asks.
"Yeah, it was pretty vivid for a nightmare," you reply.
You rub your drenched forehead in relief. The realization that Amy was only in your dream because your unconscious body heard her come in makes you feel better somehow. It certainly doesn't explain the pain of it all but you brush that off as part of your imagination.
"Yeah, giants can be scary, right?" Amy says.
"Yu- wait, I never said anything about giants..."
Ignoring your question, Amy stands up, towering over your reclining body. It reminds you of the dream in a way though without the imminent fear of death. She's wearing a devil's grin and a dominatrix's posture; you've seen this before. Amy LOVED to humiliate her dear big brother, forcing him into all manner of awkward situations. Her favorite was to shove her butt into your face and force you to kiss it. You never did obviously but that didn't stop her from trying.
Right on cue, the brunette pivoted, turning her gym-shorts clad butt towards you. The fabric did little to hide its beautiful form. Even as her brother you had to admit that she had the nicest backside you've ever seen aside from that Sophomore Emily. It was expertly toned; it's tight form brought about by hours of lower-body exercises. You weren't attracted to it, of course, but you weren't blind to its brilliance.
Normally, after Amy telegraphed such an obvious play, you'd dodge out of the way and give her a light slap. However, for some reason, you find yourself unable to move. Her ass collides with your face, the round shape engulfing most of your face. With a giggle she plucks the left side of her shorts towards the center, exposing the flesh of one of her butt-cheeks.
"Looks like I gotcha this time, Adam. Now give 'er a kiss and I'll let ya go!"
Annoyed, but with few options, you...
