you (my brother) and i (your FUTA sister) are sharing a bed because our aunt is visiting. i get to be the big spoon because i am stronger than you. (filmed with me cuddling a body pillow representing you, NOT POV) At first i just cuddle on it, but then i get more aroused and start rubbing my cock against it, and finally i mount it and hump it strongly. "What's the matter, big brother? Don't like me rubbing on you in the middle of the night? Well, try to stop me. Aww. Do you remember when i was a much smaller girl and you were stronger than me? Seems so long ago..." I continue to mock you for being little and weak and unable to stop me from humping you, for the next 5-6 minutes. I mention how you must feel like a little zebra who's been taken by a big strong lioness or something!" then growl (grrr) at you here and there throughout the clip. last part is POV: i am looming over you after i have flipped you on your back so i can play with your penis. i babytalk you as i compare your little cock with my big one, but i decide its no fair that you don't get your cock rubbed. i take you between my index finger and thumb while i continue to grind against your hole and you cum after just a few strokes. i laugh at how littIe effort it took. i have been rubbing on you for ten minutes and i am not even about to come! "Weaker, smaller cock, more submissive, less stamina -- you are not the big brother. you are the smaller sister!" i say how YOU should be the one pleasuring ME! i move to have you start rubbing me, while i continue to talk down to you. i make you rub my giant cock by your face so at the end i can give you a nice big facial from your BIG sister.
