My name is Martin, but most folks call me Marty. I'm 37, married to my beautiful wife Angela. We have a nine-month-old daughter, Emily. Before the baby, my wife had as voracious a sexual appetite as I did. Since then, between our jobs and raising our newborn, the sex has fallen off considerably. It's still very good. Just not as frequent as I would like.

We still try to have "date nights" as often as possible, and when we do, there is an 18 y/o girl named Sara who babysits for us. Sara is very pretty, in a wholesome sort of way, but I feel that under that wholesome exterior is a wild young lady. She is about 5'3", with blond hair that she usually has in a ponytail. Blue eyes and fantastic legs that she shows off in shorts or miniskirts.

She likes to flirt with me when Angela isn't looking, but we've never done anything together other than this so-far harmless flirting.

That brings me to last night, and my desire to change that vibe into something much naughtier. Angela had to go away on business for several days, and my horniness grew by the day. By yesterday, just jerking off wasn't cutting it. I called Sara and asked if she could come by and babysit tonight. She didn't know Angela was out of town, and happily agreed. A college girl could always use some extra money!

It was late spring, and the weather was unusually warm. The temperature was in the mid-80s. Sara arrived wearing shorts and a t-shirt. It was clear she was not wearing a bra, but I had learned that was not unusual for her. I could vaguely see the outlines of her nipples, but it wasn't anything scandalous by any means.

I was also wearing shorts and a t-shirt because of the warm weather. Sara looked at me curiously.

"Where's Angela? You're dressed very casually for a date night. Where are you going tonight?"

I took a deep breath. "Angela is away on a business trip this week. I was just feeling so bored, and I thought about how much I enjoy your company, so I pretended Angela and I were going out. I just wanted some company tonight. Don't worry. I'll still pay you your babysitting fee. I hope you don't mind my little deception. Emily is in her crib sleeping already."

She gave me a rather naughty little smile. "That's not like you, Marty. Just what did you have in mind, because honestly, I'm up for pretty much anything, but since I'm the babysitter, we can't actually go out anywhere, now can we, you naughty man!"

I honestly blushed at her words, but they also caused my cock to stir in my shorts.

Sara approached me, and to my surprise, she put her arms around my neck. "I think you know that I find you to be a very cute guy, but what would Angela think if she found out?"

She pressed her body against mine as she looked into my eyes with a smile. I was beginning to realize SHE was doing the seducing, not me!

"W-well, it should probably stay as our little secret, but would you like to hear something really naughty that Angela said to me one night?"

"Mmm, I'd love to hear it. What did she say, Marty?"

"We were in bed one night, just last week. In fact, it was the night you had babysat for us. We had been fooling around, and we were both naked, when she said, 'You know, I think Sara is really cute, don't you? I've seen you looking at her and her sexy little body. It's ok. I don't mind. Do you ever imagine seeing her naked, or fucking her?"

"Oh my God, she really said that?"

"Yes, Sara, she did. It was the right kind of sexy mood that she was in. There was no jealousy in her voice, so I told her, 'Well, yeah. I've thought about it, but do you blame me?' She told me, 'Not at all.' Then she straddled me and lowered herself onto my cock. 'Pretend I am Sara!' she told me."

Sara pressed herself tighter against me. "What did you do then?" she whispered.

"Angela started riding me. She was so wet! I reached up and played with her tits. 'Your titties feel so nice, Sara! Do you like my cock in your tight young pussy. I've dreamed of fucking you, Sara!' Then Angela said, 'Fuck your dirty little babysitter! Cum in my hot little teenage cunt!' We went on like that until we both came, and I filled her pussy with my semen."

At that point, Sara pressed her lips to mine and pushed her tongue into my mouth. We kissed passionately and frantically. Sara broke the kiss. "I want you, Marty! Fuck me! Fuck me anyway you want. I'm on the pill. I've let boys fuck me, but it's never that good. I need a real man, an older man like you, to teach me. Take me to your bed. Fuck me in the bed where you fuck your wife!"

We hurried upstairs to my bedroom. "Undress me, Marty. Strip me. Make me your little slut!"

I pulled her t-shirt over her head, and her bare breasts popped into view. They were so beautiful. Pale, firm, and perfect with luscious pink nipples that were hard and erect. I squeezed them and then lowered my head to them. My tongue swirled around her nipples, each one in turn, and my teeth gently nipped at them, making her moan.

"Oh, God, Marty! That feels so fucking good! You're making my pussy so fucking wet!"

I unzipped her shorts and pushed them down her thighs. Underneath, she was wearing a sexy, pale blue thong. I pushed her down onto the bed, and she looked up at me as I took off my t-shirt. My chest is virtually hairless, which I hoped she liked. I undid my shorts and pushed them, and my boxers down in one thrust.

My cut 6 1/2 inch cock bounced into view, and Sara licked her lips at the sight. I reached down and hooked my fingers in the waistband of her thong. She lifted her hips from the bed, and I peeled them down her luscious thighs.

I couldn't believe my good fortune, having this beautiful 18 y/o college girl lying naked in my bed, waiting for me to use her. She licked her lips in anticipation of what was to come. I parted her thighs and lowered my head between them. I breathed deeply and inhaled the scent of her perfect young cunt. She was shaved totally bare, just the way I like it.

My tongue snaked out, and I ran it up and down the length of her slit, and then I pushed it deeper inside her to taste every portion of her love hole. Her taste and scent were exquisite!

My tongue found the hard little nub of her clitoris, and she gasped audibly as my tongue flicked rapidly over it.

"Oh fuck. Oh fuck. That feels so good, Marty. Oh God, I'm gonna cum! I'm gonna cum! I'm Cummminggg!" she screamed as a torrent of juices bathed my face. I used my tongue to lick up what I could of her nectar, but there was too much for me to reach it all.

I lay on top of her. "Lick my face clean, little girl!" I ordered her. Greedily, she lapped her own juices from my face.

"Oh, Marty, this is already better than anything those boys I let use me have ever done to me. All they want is to get themselves off, and to hell with my feelings. I knew a man like you would want to please me, as well as yourself!"

She sat up, and I knelt in front of her, pushing my throbbing cock between her lips. She began sucking my cock, and the swirling of her tongue on my shaft told me instantly she knew what she was doing. She may have been only 18, but she knew how to properly suck a cock!

Her hand cupped my balls, and gently squeezed them as her lips and tongue worked their magic. I wanted my first load to be in her pussy, though, not down her throat.

I popped my cock from her lips and told her, "It's time for you to have a real man fuck you!"

She smiled lewdly. "Stick it in me, Marty. Fuck me. I want to be your dirty little whore!"

"You do, do you? Then get in doggie position, ass up, and head on the pillow!"

She got into position, and I gazed admiringly at her tight little ass, her glistening wet cunt, and her puckered little sphincter. I'm going to take that little butthole soon. I hoped she was a virgin there, so I could be her first. For now, though, I want that wet, bald pussy.

I squeezed her ass cheeks. "Have you ever been spanked?"

"Not since I was a very little girl, by my mother. Do you want to spank me? Will you hurt me?"

"Oh, I do love spanking a pretty ass like yours. I won't be too harsh with you. At least not this time."

"Okay, Sir. I trust you. Do what you want to me."

My cock was rock hard and rigid. I placed it at the entrance to her vagina, and it slid in easily, as wet as she was. I gripped her hips and began thrusting. As I fucked her, I raised my left hand and brought it down fairly hard on her left cheek.

SMACK! Her cheek jiggled. She gasped at the sharp slap. I raised my right hand and smacked her right cheek.

"Oh, that stings, Marty, but it's not too bad. I love submitting to you. Fuck me. Spank me!"

I continued thrusting my cock in and out of her willing cunt, even as my hands continued spanking those sweet ass cheeks. Soon her ass was a lovely shade of pink.

I stopped slapping her and focused on fucking her. Her moans were only of pleasure now, and I picked up the pace, RAMMING my cock hard in and out of her fuck hole. "Oh, Marty! Fuck me! Fuck me HARDER! I'm cumming, Marty. Fucking USE me!" she cried as a massive orgasm overtook her. She squirted like she was pissing, soaking my sheets, as I also came, flooding her young cunt with my spunk.

Finally, our orgasms subsided. I slipped out of her pussy, and lay beside her. She moved down and took my slimy cock between her lips, cleaning me of our combined juices.

"We taste so good together, Marty," she told me. "Would you clean me like I cleaned you?"

I happily obliged and lapped up her and my cum from her love hole. She was right. We taste so good together!

We lay together, kissing, cuddling, and fondling each other.

"That was so amazing, Marty. I've never cum like that in my life. I still can't believe your wife role-played that she was me in bed with you last week. I've masturbated several times imagining you fucking me. It wasn't nearly as good as the real thing! Unfortunately, my parents know I am here, supposedly babysitting for you. I should get home soon. It's getting late. When does Angela come home?"

"Not for another three days."

She gave me the naughtiest of smiles. "Tomorrow, I could tell my parents that I'm going to sleep over at my friend Janine's house. We do that pretty often. I'll tell Janine my little lie, so she can cover for me if, for some strange reason, my parents want to reach me. My Mom is old-fashioned enough that she might call Janine's parents' landline instead of my cell. That way, I can come here tomorrow and spend the night. Do you want me to do that, Marty?"

"That would be amazing, Sara. Are you sure you are safe doing this? I don't want to get you pregnant!"

"Don't worry. I've been on the Pill for over a year. I'm a bad girl, you know. I deserved that spanking you gave me. I liked it."

"This is a super personal question, Sara, but has anyone taken you in the ass?"

"Fucked my butt? Oh my God, no! I don't know if I'd be ready for that!"

"I understand, Baby. I won't push you. But I hope you will save it for me. I'd love to take your virginity there when you feel you are ready."

For the first time, I saw her really blush. "I've never even thought about that. Do men really like to fuck a girl's ass? Isn't it gross?"

"Oh, no, Sara. It's wonderful, especially for the man. I love the feeling of my cock in Angela's ass. There is no feeling like it."

"Does Angela enjoy it?"

"She does now. She did it to please me the first few times. I won't lie. It will almost certainly hurt the first time or two, but I promise to go slow and to be careful. I know a few tricks to help make it feel better!"

"Okay, Marty. I'll trust you. But not tomorrow, okay? I'm not ready for that yet."

I smiled. "No worries, Princess. Not until you feel ready. Now, you'd better get dressed and get home. I know you are nearby, but do you want me to walk home with you?"

"That's okay. I'll be fine. If my parents saw you walking me home, they might start wondering. I'll text you when I'm in."

She got up reluctantly and put her clothes back on. "I hope they are asleep when I get home. I must reek of sex!" She giggled.

I said, "Wait! I promised to pay you your babysitting fee." I got my wallet and paid her.

She laughed. "Now I feel like a hooker! I really am your whore now! I love it!"

She left, and five minutes later, I got a text. "I'm home, and they are in bed. I can't wait until tomorrow."

Neither could I!
