Her 18 year old son, Tommy....

"Hi..." said the voice on the other end of the phone, "Mom?"

"Oh yes..." Darlene gasped as soon as she recognized her son's voice and she lowered her leg back under the bubbly bath water, "hi honey."

"Are you OK mom?" Tommy asked.

"Oh yes dear I-I'm fine. It's just that you caught me off guard. That's all." she quickly replied catching her breath.

"Oh? What did I interrupt?" he asked.

"Nothing really." Tommy's naked mom answered, "I was just....I was just taking a nice hot bubble bath. That's all."

"Sorry mom." Tommy quickly replied as visions of his mom's nude boby soaking in the tub suddenly flashed through his head.

18 year old Tommy Smith never really thought of his mom in a sexual way but through the years he couldn't help but notice her curvy 5'8" frame, especially with the daring little outfits she always seemed to be wearing. He always seemed to be taking a ribbing from his friends as they teased him about his hot bodied mom. Darlene was a true MILF in their horny young minds. After a while even Tommy begin to look at her in a different way, especially when she was wearing one of her teeny tiny bikinis around their private back yard pool.

"It's alright honey I'm almost done anyway." she joked.

"Don't hurry on my account." Tommy laughed unable to get the image of his bathing mother from his mind.

Darlene thought that Tommy was calling her from his college, several hours away. Little did she know that he was now just a few blocks away. He knew his father was out of town again and hoped to pop in on his mom and surprise her with a visit for a few days.

Tommy's cock suddenly got hard as he heard the bathwater splashing around a bit as his mother moved herself around the tub. For some reason, the thought of him talking to her while she was completley naked in the tub was rather exciting.

"I can't stay in here all day you know." she told him, "I don't want to get water logged and turn into a prune."

"Awe mom I don't think that would ever happen." he said, "How's the water?"

"Oh it's very nice." she told him, "It's so nice to be able to just relax and soak in a nice hot bubble bath."

He swallowed hard as he heard the bathwater moving again and wished he could see what his mother was doing.

Darlene too was getting excited by the thought of talking with her handsome son, who she thought was miles away at school, while taking a bath.

"So what have you been up too?" she asked as she slowly allowed her fingers to return to one of her huge breasts and she began to pull at her erect nipple.

"Oh nothing much. Just the same ole stuff. Go to class, study and go back to class." he told her as he turned his car into the driveway.

"Uh where are you?" she asked as she realized he was on his cell and probably in his car.

"I'm just driving." he told her.

"Oh good." she replied having no idea he had just pulled into her driveway, "Just be careful talking and driving at the same time."

"Don't worry I will be careful." he said as he shut off the car and stepped out, "Uh when's dad due back?"

"Not for a couple more days." Darlene answered, "His trip got extended."

"Sorry to hear that." Tommy said as he stepped towards the front door and pulled out his house keys, "So you're all alone then?"

'Yeah." she giggled as her hand moved down between her legs again, "Just me and my bubble bath but I'm glad you called it's so nice to talk to you honey."

"It's nice to talk to you mom." he said as he unlocked the front door and quietly slipped inside, closing the door behind him.

What does Tommy do next?

Sneak up the stairs or tell his mom where he is?
