Jon heard Sarah's wish, so she knew knew her feelings were magically induced, but that didn't matter... her female body craved Sarah's attentions. She needed him, now!
"Oh god, Sarah, I want you! Fuck me now, on my old bed," Jon sighed seductively as she crawled onto the bed, wiggled her ass and still kneading her breasts.
Sarah was incredibly turned on by the gorgeous naked girl in front of him, and he quickly shed his clothes and took her from behind. She moaned and cooed, apparently enjoying every second of it, though in her mind Jon was stunned and disgusted by what was happening. She was unable to say or do anything to make it stop, though, and her body orgasmed repeatedly, sending mind-blowing shockwaves of pleasure coursing through her soft female form. Sarah took her in at least 3 different positions, and as a former girl, he knew exactly what to do to drive her wild.
After Sarah was spent for the last time, both collapsed heavily on the bed, sweaty and panting. Sarah said "That was just incredible, I can't believe we just did that! I'd always wondered what it was like for guys, but I have to say, I think girls get more out of it."
"I love you so much," Jon breathed in his ear, nibbling it a little, as her hand snaked down between his thighs once again.
"Enough for now Jon, I'm tired. I'm going to the bathroom, you get dressed, we've got to get out of here before your family gets home." With that, Sarah climbed out of bed and headed toward the bathroom. Jon, fighting the urge to obey she loved, remembered why she had come for the stone in the first place. She hopped lightly off the bed, cum still clinging to her tits and dribbling out of her pussy, and reached for the stone.
"I wish Karyn were still alive," she said softly, and the stone shined brightly for a moment. Whether Sarah had heard the wish or saw the light, he, rushed back into the room and saw Jon holding the stone. Before she could say another word, he lept across the room and tackled her soft, curvacious body, and grabbed the rock out of her hand. He sat on her waist, and held both of her arms over her head with his other hand... he was much stronger than she was. Jon struggled helplessly at first, but her female body quickly realized her lover was on top of her and pinning her down, and she immediately grew wet again.
"I never should have left you alone with the stone," Sarah growled. "It's a good thing you didn't make any wishes about me, but we'll have to make sure that you never do... I wish..."
