Lose yourself in the moment

The feel of your cock in hand, whilst staring at the stunning body of your oldest sister is intense. You imagine the way her body would feel against yours, the touch of her lips on your skin, the play of her breath over your cock, the scent of her. You lose yourself to daydreams, and are shocked when you feel an alien hand placed next to yours along the length of your member. As you open your eyes, a hand covers your mouth to stifle your surprise as you find Arya - her face as shocked as you feel - staring entranced at your length.

Your mother and Sansa still remain, discussing somewhat less aggressively than earlier, whilst Arya slowly looks up from your cock to your face. Hidden largely by the stone corner of the corridor, she takes her hand from your mouth and places a finger to her lips, silently muting you, before continuing to jerk your cock.

"Arya!" you whisper with as much **** as you can muster, before, with one final look around the corner at her mother and sister, she drops to her knees before you and engulfs your dick in her wet, warm, teenage mouth.
