This throws her off, as she had expected you to enter her.  Not this, as you slide to position right beside her head.  An then tell her to use her mouth to get you ready.  Which it seemed you were already.<br/><br/>She tilt her head towards you, she would capture your bulbous head into her lips.  Then draw in more of your cock into her mouth.  As her tongue seemed eager and lapped the underneath.   An then you feel the draw of her mouth working as she began to suck you off, in preforming a blow job on you.<br/><br/>Working feverishly to gain your cock inside of her.  Without realizing it herself.
