"That thing would kill me," she argued, getting hotter by the second.

"I'll be gentle," he panted, crawling up between her legs.

"Will you stop if it hurts?" she asked, wanting to fuck as much as he did.

"Yes, honey," he answered, guiding his stiff boner up toward her slit.

Heather was trembling with apprehension, feeling the heat of his blood-engorged cock burning against the sensitive flesh of her soft inner thighs as it slowly advanced toward her hot aunt. Feeling his pulsating cockhead lightly touching her soft fuzzy pubic hairs, she reached down and grasped his bloated shaft, sliding the tip of it up and down against the juicy wet lips of her slippery twat. The head of his prick was soon glistening with her hot juices that were dripping onto his throbbing knob.

She began slowly guiding his big cockhead between the passion-swollen outer lips of her aunt and up against the hot opening of her dripping pussy. Arching her hips, she reached for his ass and gently drew him toward her.

"Oh, God!" she gasped, feeling the big swollen knob slip through the tight elastic opening of her tiny hole. "Please don't move, Tom. This really hurts."

When she felt him start to withdraw the tip of his prick, she grasped him tightly.

"You don't have to take it out," she whispered, clinging tightly to him. "Just lay still for a minute."

When her tense body began to relax a bit, she carefully arched her hips a bit more, feeling his thick cock sink a deeper into her cunt. This time there wasn't the pain of the initial penetration.

"Am I hurting you?" he asked.

"A bit," she whispered. "But it's O.K."

Heather continued arching her hips and drawing him into her, feeling his big dick slowly expanding the tight walls of her tiny slit. She could feel delicious sensations flowing through her body as his thick boner pressed out against the sensitive nerve ends of her tightly stretched tissues.
