Stay cool and reassure her ... that is get her naked!

I was shocked. I wasn't even totally sure how old Alison was. For all I knew I was adding to the delinquency of a minor. I'd be lying if the thought wasn't arousing, but my sense of right or wrong was a little stronger.

"I don't think that's the best idea," I said.

"I won't tell anyone, Mr. Carter," she said coming closer. "I'm just curious. All of the guys I've screwed around with aren't really men, and I'd like to see a real man for once. It's not like we're going to have sex."

I still hesitated. My desire to actually do this versus my moral sense was battling. Alison seemed to see I was struggling with it, so she decided to up the ante. She sat down next to me and unbuttoned her shirt. It fell open to show a bra hugging a small pair of what looked like B-cup breasts.

"Please?" she said and lifted the towel away from my crotch. My cock sprang up. She reached up and undid the clasp on the front of her bra. Her breasts leaped free. They were fucking perfect.

I reached down and took my cock in my had. Alison licked her lips and sat back, watching intently. I started stroking it slowly. Her eyes were riveted to it. After a minute I increased my speed.

"Oh wow," she whispered.

My speed increased faster. I was getting into it now. I put some more lube in it and started jerking it faster and harder. Alison was watching me as if her life depended on it.

After another few minutes I was getting close. The situation was too much. I had to cum.

Alison seemed to realize it.

"Yeah, c'mon. Do it. Cum for me, Mr. Carter!" she moaned.

That was all it took. The sound of her voice pushed me over the edge. I started to cum. Alison squeaked with delight and actually came closer to see better. I shot all over and one stream went up onto her arm and partly on her shirt and chest. When the cum hit her, she let out another little moan.

I sank back. She still stared at me.

"Holy Shit, that was intense," she said.

I wasn't sure what to do, but then Alison shocked me even more with her next sentence.

"My turn," she said.

I had just shot my load in front of my teenage neighbor who, not knowing I was home, had caught me in the act of masturbating when she came over to feed our family dog.

I didn't know what to do. Since I had just cum, I was 'coming to my senses'. What I had just done was really not a good thing.

Alison was still staring at my cock. She picked up the towel she had lifted from my crotch only a few minutes before and wiped off the cum that had landed on her. Then she handed the towel to me.

I cleaned myself up and left the towel covering my dick. Alison chuckled and lifted it back off.

"I still want to see it. You have a much larger cock than my boyfriend does," she said.

"I'm at a loss here, Allie," I told her. "I'm sure you know that this is really wrong... I mean-"

"I know, you could get in trouble. It's okay," she replied. "I'm not going to blab to one of my friends or anything. None one will ever find out. I promise."

Alison them took off her shirt, which she had unbuttoned earlier. She slipped off her open bra also. She was still next to me topless, her long brown hair now partly covering her breasts. With the shirt and bra off, it now looked to me that her breasts were a larger A cup, not the B cup I has guessed on before.

Alison kicked off her white sneakers (she wasn't wearing socks), leaned back, then unbuttoned her jeans. Despite the fact I had just cum, I felt my cock move.

"Allie, we really shouldn't..." I tried to protest one more time, knowing that my desire was really overcoming my sense of morals at this point.

Alison stopped at looked at me intently.

"There isn't one guy I have dated who has given me enough of a charge where I wanted to masturbate in front of them," she told me. "I know we shouldn't be doing this... I babysit for your kids for Christ's sake... but I'm really... and I mean REALLY turned on right now."

With that, she pulled her jeans off. She wasn't wearing panties underneath. I wondered if that was uncomfortable.

Alison's pubic hair was very light and neatly shaved into a thin landing strip. The desire to touch her was tremendous. She was now totally nude. She was very thin and petite. I hadn't seen a body like hers in person since my wife and I were in high school.

Alison turned her body a little to rest against the armrest and opened her legs. She slid the middle finger on her right hand into her mouth and sucked on it for a second, then lowered that finger to her pussy and started to rub her clit.
