you (my step-brother) and i (your FUTA step-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 step-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 step-brother. you are the smaller step-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 step-sister.
