She wasn't positive what he wanted.  Sure, it wasn't that she was completely unfamiliar with how to do it despite being a virgin, but she knew of several positions that could probably be plausible.  In the water, a whole bunch of them probably weren't very feasible, but as he tugged her back into him, Sarah just gave up trying to guess and let him have his way with her.  At first, it was just kissing while she felt his hands groping about her body, the small bikini she wore not doing anything to impede his touch.  Though as he ducked to her breasts and joined in fondling them through her bikini bra, she sighed with some pleasure.  "J-just don't grab too hard..." she said, his awkward caressing not exactly thrilling, but the touch from someone else alone was enough to get her at least somewhat excited.<br/><br/>The loud snap of the twig got her attention, though she never got an opportunity to look back before the gruesome sight unfolded before her eyes.  "M-mark!?" she uttered in dismay before his body just seemed to fling itself over her, the crimson rapidly covering her toned body highlighting her otherwise peachy skin.  She couldn't help but turn around and stare in utter shock at the huge man that stood there.  It felt like ages that the two just looked at each other, but seeing her boyfriend's body twitch like that... and the sudden thump of the weights... Sarah couldn't stick around.<br/><br/>She immediately dove underneath the surface of the water, giving her the ability to jettison off from the wall of the shallow spring and gain a huge head start before she emerged on the other side of the spring, rolling out as the blood washed off, only for the soft dirt to cling to her wet body.  Launching herself up on her feet, she took off, running straight into the woods as fast as she could, the image of Mark's bloodied and mangled face still seared into her mind.
