Fuck her pleasurably

While you could fuck Betty's ass right now, you don't feel right about it. You're still going to fuck her - just not there. You aim your cock at her exposed pussy and slowly make entry.

Once you are fully inside of her, you feel her pussy clench a little. If she's truly out of this, it must be a reflexive action.

You take her ankles and pull them back up on your shoulders, giving you a little more leverage.

You start to get a good rhythm as you fuck her now. Her prone body just lets you use her to your heart's content. Not wanting to be a *complete* jerk about this, you reach down and start to rub Betty's pussy lips. You play with them a little, uncovering her clit. Thank you, Internet! You feel her pussy tense up a bit now, but don't let that stop you. You softly rub her clit now, pressing on the 'button' to stimulate her even more.

Betty mutters something, seemingly-still asleep.

Taking full advantage of this situation, you reach forward with your other hand and play with her breasts. They feel so good!

All of a sudden, you feel some juices push out of her pussy, soaking your groin and the area around it.
She came!

As you feel your own orgasm building, you pinch her clit a little, getting another reaction... A bit of juice shoots out from just above your dick, spraying you a little. Thanks to the Internet, you know what that was!

Speaking of which, you are nearly there. What to do...
