Keep up the sleep pretence [Ending C2]

You can't risk anything to rash, and things have gone pretty well so far, and you can hardly be held to blame for this right?

You really want more of your dick inside her mouth, but her tiny little licking laps, and suckling is pretty intense and feels great. Her cute little pleasured moans all adding to the horny situation.

As she continues slipping and slurping away at your tip you realise there is another wet squelching noise, this one coming from her busy hand between her legs flicking and sliding away at her tight virgin vaj lips.

This sound and mere thought of her tight little entrance sends to you to the next level and you feel that unstoppable trigger has been set off. Oh gees! Here it comes!

Amy's moans build, the slopping of her pussy increases to an incessant wet slapping and it sends you over the edge.

Your cock begins to throb and pulsate as the cum travels up your shaft, Amy must somehow sense it as she backs away just as the first hot rope explodes into the air. As she withdraws it catches her on the chin. She lifts her head up a long pearly string hanging and swaying then flicking against her throat.

The second, third and fourth follow flying onto your belly.

Amy is shocked by the white eruption, she staggers back, eyes wide. She falls and lands on her arse sitting legs akimbo on the floor by the bed.

"Oh! Oh my! What...? What is it?" She says to herself as she tries to wipe it from her chin and mouth but not expecting the unusual sickness, she becomes confused.

Through the crack in your eyes you look on, and then realise in her current position you can see right up her nightdress between her legs getting a clear view of her tight virgin twat.

Her tight vulva has opened slightly in it's puffed up aroused state, revealing the deep pink inners of her narrow hairless pussy-hole. A final strand of love muck flops out onto your pajama top and belly.

Amy then gathers herself and picks herself up and scarpers out of the room still wiping the weird white stuff from her face.

Holy shit that was hot! Not only did she lick you off but you got to see her sexy little wet hole. You feel so wrong, but in that moment you realise even though she is your girlfriend's sister, you'd almost do anything to bury your cock in her little love palace.
