Stealth and suprise

You wander back into your room, climb onto the ledge of your window and lean out. A little further on you can see your neighbour Helen's window, slightly ajar to let out some of the stifling heat. Below you is a 5 storey drop; previously you would have gulped in fear at the sight, but such things are below you now.

You leap the gap, your large wings unfurling to allow you to glide gently around onto Helen's windowsill. Inside you can see Helen, her back turned to you, watching a television you cannot quite see. She seems to have one hand inside her tight jumper top, and the other is hidden somewhere in her lap. You smile, and lick your lips with anticipation.

Feeling Jess still inside the building, you send a quick mental message to her. A few moments later, Helen wanders towards the door, swaying enticingly, the line of her panties showing through her thin cotton skirt. As she moves to answer the door, you silently slip through the window, turning as you do so to allow your huge, erect phallus to pass through the small gap. You secrete yourself inside her wall cupboard, leaving the door a little ajar (You cannot close it anyway; your cock is simply too large to fit) so you can watch her.

When she returns from the door, looking a little puzzled, you see that Helen is now idly running her hands over one of her wonderfully firm tits. She doesn't even seem aware of what she's doing. As she turns back towards the TV, you can smell the telltale scent of arousal from her. You sieze the moment, step quietly out of the cupboard and slide behind her, running your hands over her as you whisper "Guess who?" into her ear.
