Dont wake her

You contained yourself thinking the situation through, and learned closer edging your way to her pussy you start licking it seeing if she'd stay asleep, as you started to get her pussy wet she kept moving and fidgeting you knew she would wake up if you continued.

You decided to chance it anyway and started tugging on your cock building your orgasm up staring at her pussy you thought just the tip in her pussy would be enough to make you cum. So you crept up the bed and placed you rod at her entrance and you started to rub it up on her clit and down into her pussy entrance, you heard Sarah moan slightly and froze with your tip half in her pussy. She wrigled on the bed riding further up on your cock bringing you to orgasm shooting cum in her pussy trying not to moan as you did, you filled her up and then some leaving a pool of your seed underneath her.

Sarah woke up for a second groggy, she looked over at the clock then at you and asked "what're you doing down there, why are you down there" she reached down "did you? is that cum? " you didnt say anything you could feel her fury and you knew she was going to punish you.
