Inside her.

"Cum inside me!" she pleads, pulling you even closer to her.

With her arms and legs locked securely around you, you couldn't pull out even if you wanted to. Lighting cracks outside as you fire off, coating her insides with your cum. Lily's head is thrown back and her breathing becomes ragged. "You came. You came..." she pants, dragging her nails across your back. "I can feel them. All your swimmers wriggling around inside me. Oh fuck, oh fuck..."

With sweat dripping off your brow, you pull your head free from her grip and try to catch your breath. But she pulls you back in and kisses you. "Stay close to me, please," she begs, looking into your eyes as thunder rumbles in the background. "I'm not scared if you're near me. Please." You nod weakly and blindly reach over to the bed. Pulling down a pillow and the blankets, you make her as comfortable as you can before you fall asleep on top of her, your cock slowly softening inside her.
