Jerk Her Off To Lower Her Defenses.

You manage to keep your desires in check and take a less direct approach. Using your knee on her chest to keep her pinned your hands start to work on her lower half. Heather slams her hands into the floor as you pump her shaft and run your fingers along her slit in search of her clit. She's putty in your hands. You jerk her off faster and faster while your other hand pumps two, then three fingers in and out of her passage. You feel her contract around those fingers just as she releases several streams of cum from her tip, making a mess of you both but mostly her. She flops like a fish and her expression grows vacant. You can faintly see the gas gathering across the floor where her head lays.
