What did that mean? I gave her a nervous smile and forced a laugh,

"Hey, you have someone hiding under the bed?"

"Not under it, but maybe on it."

"On..." I stopped when she put her hand over mine.

“You know, today is my birthday and it was going to be a happy one.

Know why?"

"You were going to um...have nice night?" As bold as I had been I wasn't about to say ‘get laid’

"I was going to cut loose tonight." She tugged on the top of the robe, "I haven't worn this in a long time and I went out and bought something sexy for under it." She giggled “I think I blushed when I paid for it."

"Bet you did," I looked down as she ran her nails across the back of my hand and up my arm.

I shivered at the contact and my cock swelled as I let my eyes wander down to her chest where the robe had opened more form her pulling on it.

"I did, but when I got into it I felt so sexy!" She smiled, "I was so looking forward to not being such a good girl tonight." She sighed, “But then Ralph turned into a pig and I guess I'm glad it was before and not after."

“I agree."

“So I figured the night was ruined, then a good looking young man brought me flowers and told me how beautiful I am." She coked her head and winked at me, “And I know he's not lying because he's been staring at me since he came in my room."

My face grew hot, but not all with embarrassment. Her nails were running up and down my arm and my eyes were blatantly on her breasts and as she had just said, she knew it. Her breasts were rising and falling rapidly and when she stopped moving her hand and left it on my bicep I could feel her fingers trembling.

My heart raced at the thought Robin was into me and my cock was now fully erect and aching with desire. I was torn between going for it and kissing her or letting her make the first move in case I was wrong or she decided to change her mind.

“I have been looking," I said softly, "I like what I see."

“And I like you looking," she replied, “Which brings me back to my birthday."

Robin gave me a nervous smile that caused my heart to flutter and my cock to twitch, "I think that maybe, just maybe I might enjoy my birthday after all."

"Yeah?" I swallowed nervously as she caressed my cheek and leaned closer to me.

"Well, its up to you, Sam." Her face was inches from mine and her head tilted to the side as she continued, “Do you want to give me a lonely, sad woman a happy birthday?"

I had to hold back a ‘hell yeah' and as I paused to try to say something that made me sound confident, I recalled who Robin was. She wasn't just a hot milf she was...

“But, Dave." I said, pushing the words out so I wouldn't change my mind, “He's...my friend."

“And he's my son and he's been pushing me to have fun, my son wants me happy. I think you can make me happy, Sam." She squeezed my arm,

“I'd like to make you happy, after all we were both treated poorly tonight, so how about we show those jerks and have some fun together?"

"You...you won't tell him?"

Robin shook her head and stood up. Thinking she had changed her mind

I asked,

“Hey, um...where are you going?"

"Nowhere." She lifted the ties to her robe and held them out to me,

"I thought maybe you might want to un-wrap me and see what I bought today."
