Try to see if you can get her naked
From Create Your Own Story
On the TV, the porn star has now removed her "Sex Skis" entirely, and is rubbing her pussy up and down on the man's shaft. You motion to Kara with your head to look at the TV. She watches the scene for a moment, not releasing your cock from her mouth, before looking back at you. You smile at her and nod suggestively, and she smiles back, releasing your cock. She stands up, and shimmies out of her pants and panties, letting them fall to the ground. You can't believe she's being so forward! And right in front of her own brother...
Shayla stops staring long enough to notice Adam ogling his little sister. She turns back at him. "Ugh, gross, Adam! Your own sister?" She hits him on the shoulders, but not very hard. Adam just gulps and keeps staring as Kara giggles at the exchange, and straddles you again, rubbing her little slit up and down your shaft. Her slick pussy leaves your dick shiny with her secretions. "Ahhhhh," she moans, running her hands through your hair.
"Are you getting harder, Adam?!" Shayla says incredulously. She undoes his pants and hastily fishes his cock out. "Oh my god, you are. Look at that. Are you twitching? Jesus, Adam." Her face doesn't match her words, though... she clearly finds this hot.
Kara pays no heed, now grinding her swollen clit on your cock and moaning like a whore. You grit your teeth, watching in awe as her little slit rubs up and down your cock. "Jesus, Kara..." you groan, watching her slide and writhe, raising up her shirt to squeeze her perky breasts. This is clearly not about making Adam and Shayla jealous. She looks at you with half open eyes.
"Don't you want to fuck me??" she says, pleadingly.
