I stood on the covered porch, shifting my weight from one foot to the other. In the distance, thunder rumbled, and I had to hide a smile. Even the weather was cooperating with my plan.

My friend's dad finally opened the door, looking surprised to see me. "Hey, Mandy! How are you?"

I gave Gavin an extra innocent smile. "I'm great. I stopped by to say hi to Reese." As I spoke, I noticed the damp spots on Gavin's T-shirt. He must have just gotten out of the shower.

"Sorry, hon, but she's with her mom this weekend. They went out of town." 

Of course, I knew that. Reese had let me know her weekend plans via text. Now that we were both home from college, we kept our communication mostly digital, just as we had while away at school. 

Smacking a hand against my forehead, I said, "Damn, she mentioned that, and I totally forgot!" As if on cue, the thunder clapped louder, and rain began to speckle the sidewalk that snaked along Gavin's lawn. "I'm so sorry to impose, but do you mind if I wait inside for a few minutes?" With a helpless expression, I nodded toward my bike. "I'm afraid I'll get soaked if I try to head home right now."

"Uh, of course. Come on in." 

Gavin held the door open wider, and I beamed at him before stepping into the living room. 

"Can I get you a drink while you're waiting for the storm to pass?" he offered.

I'd never been one to waste time. In fact, the need for instant gratification might have been one of my greatest weaknesses. Turning toward Gavin, I held onto his arm for balance as I took off my sneakers.

"I'm fine, thanks. But now that you and I are alone, I'd like to talk to you about something." I kept my tone light even as the desire for revenge cast its inky shadow over my thoughts.

Gavin blinked at me in confusion. Still, he didn't hesitate to say, "Of course, Mandy. I'm all ears."

For the briefest of moments, I almost felt sorry for him. I'd known this man for years; I'd envied the close relationship he had with Reese. 

But they obviously didn't tell each other everything.

Refusing to release my grip on Gavin's arm, I stepped even closer. He smelled clean, like soap and shampoo. His eyes were a gorgeous caramel color, and his dark hair held a distinct wave. He kept in great shape. But then, he was a divorced man whose only child had left for college last year. He had some time on his hands.

Standing on tiptoes, I brought my lips within inches of his. Instinctively, he leaned forward, as if to hear a secret I might whisper.

But I didn't whisper it. Instead, my voice was harsh and flat as I said, "I know you're fucking my mom."

Gavin instantly recoiled, his eyes widening. His free hand went to his face, and I heard the scratch of stubble while he rubbed his cheek. He hadn't bothered to shave today.

"Mandy," he began in an uncharacteristically harsh tone, "I have no idea what you're—"

I withdrew, making no attempt to hide my disgust. "Don't bother lying. I read Mom's journal. She goes into explicit detail about you."

That wasn't exactly true. Mom had described her affair with Gavin in flowery, sickeningly sweet terms, but she hadn't used his name. Still, she left enough clues for me to easily figure out who her secret lover was.

Gavin blanched. "I can explain everything—"

I held up a hand to stop him. What he'd just said was as good as a confession. "I know it wasn't right for me to snoop around in her room," I said. "But I have to keep a close watch on my mother. She's prone to..." I hesitated, pretending to search for the right words. "Making mountains out of molehills. And I'm guessing you thought this affair was just a teeny, tiny molehill, didn't you, Gavin?"

His mouth dropped open, but no sound came out. I was more than happy to fill the silence.

"Normally, I wouldn't consider my mother's private life my business. But there's just one problem." I narrowed my eyes, regarding Gavin with an emotion that bordered on loathing. "She's still married to my father. My clueless, devoted father."

Gavin stepped back, the tendons in his neck straining beneath his skin. "I'm so sorry," he blurted out. "It wasn't supposed to mean anything."

I folded my arms over my chest. Outside, the rain began to fall in sheets, streaming down the windowpanes. "Oh, you can bet the scraps of attention you've given Mom mean the world to her." I recalled my mother's frantic journal entries, each one full of the drama she craved for her boring life. 

Gavin swallowed hard, the sound audible. "Are you going to tell Reese? Or your dad?"

"I should," I shot back. "I should let everyone know what kind of man you are, sleeping with a married woman."

His face grew pleading, and I could barely stand to look at him.

"But I don't want to hurt my father," I went on in a quieter voice. "If he found out about this, it would destroy him." Flipping my long blonde hair over my shoulders, I made a point to thrust my tits in Gavin's direction. "Fortunately for you, there's a way to buy my silence."

His muscles tensed; he was gritting his teeth so hard that I saw the clench of his jaw. "Name your price," he said.

I allowed my gaze to roam over him, from the top of his head all the way down to his bare feet. His shorts revealed his strong legs.

"The thing is..." I started lifting the hem of my shirt, flashing a hint of flat stomach. "I think you're so goddamn sexy, Gavin. When I was at college, I would often fantasize about you while I touched myself. Made me come every time."

He drew in a sharp, startled breath. "You're Reese's friend. I can't..."

"And you've been fucking my mother!" I snapped before regaining my composure. Forcing the sweet smile back onto my face, I added, "I'm nineteen. An adult who can make my own choices. And I want..." I stepped toward him and placed a hand on his chest. "You."

Gavin stared down at my hand, as if he couldn't fathom how it came to be there. Then his eyes snapped back up to meet mine. 

"I care about your mom," he said, "but I can break things off with her today."

"Oh, I bet you can!" My upper lip curled in contempt. This man was digging himself a deeper hole.

"She and I both knew what we were getting into; she was never going to leave your dad. But you and me?" Gavin stepped away, leaving my hand cradling empty space. "It would be wrong. I'd hate myself if I..."

Rolling my eyes, I let out a sigh. I wasn't going to spend all afternoon arguing ethics with him. Instead, I pulled my top over my head to reveal the sheer bra beneath. Gavin didn't move, didn't say a word, so I set about removing my cutoffs. 

"Please don't do this," he finally spoke, but his gaze was hungry as it swept over me. 

I was soon standing in only my bra and thong panties. With a dramatic flair, I turned to give him a nice view of my ass. My skin was golden from the sun.

It was glorious, being without a trace of self-consciousness. I knew I was beautiful, perfectly capable of tempting Reese's dad. 

Facing him again, I bounced on the balls of my feet so that my tits jiggled. He stared helplessly as I unhooked the bra's front clasp. 

When I bared my firm, round breasts, he sounded like the wind had been knocked out of him.

"My God," he managed to croak.

My skimpy panties were already getting wet. Once I'd tossed the bra aside, I hooked a finger into the thong's narrow waistband. It was then that I noticed the erection tenting Gavin's shorts. 

"Someone's definitely enjoying the show!" I taunted. "Now, it's time for you to put on a show of your own. Take off your clothes."

"Mandy—" Again, he tried to assume that stern demeanor that only served to piss me off.

"Hurry up!" I demanded. "I promised Mom I'd be home in time to help her with dinner, and if I don't have your cock inside me before I leave here, my parents and I are going to have a very uncomfortable conversation at the table."

Gavin's nostrils flared with barely contained fury, yet he yanked off his T-shirt and threw it on a nearby chair. While watching him strip, I teased my nipples, rolling the rosy peaks between my fingers. He couldn't help watching. 

Still, there was something arrogant in his face as he said, "You might come to regret this, sweetheart."

"Now, why would I do that?" Licking my lips, I admired his muscular form. "I think I'm going to love every second of it."

He hesitated, just for a moment, before tugging down his shorts and briefs. When he stood upright again, and I got my first glimpse of his erection, I immediately understood his warning.

Holy shit, the man was thick! Like, as thick as my wrist! His length wasn't much more than average, but his girth? Mom never wrote about that in her journal! His pubes were neatly trimmed to showcase his intimidating cock.

Gavin raised an eyebrow, and I knew the trepidation must have been clear in my expression. "You sure you want me to fuck you?" he asked. His dick twitched as if ready to spring. "You can leave right now, and we'll never have to talk about this again."

"No fucking way!" My pride wouldn't allow me to lose my nerve. And despite the fact that my past sex partners weren't anywhere near as thick, or even as long, as Gavin, my pussy ached and dripped. "Go sit down."

He held up his hands, clearly done trying to persuade me. As he strode toward the couch, I secretly admired his firm ass. It had a little hair on it, which I wasn't used to, but that made him seem even more manly. I could practically smell the testosterone emanating from him.

Gavin sank down, draping his arms along the back of the couch while spreading his legs. He appeared perfectly at ease, with that monster between his thighs aimed upward and ready to impale me.

I took my time stripping out of my panties. When I was finally naked, I approached my friend's father, my breasts rising and falling with shallow, nervous breaths.

"Hope you're wet," Gavin said with that self-satisfied grin. "Of course, I have lube if you need it."

"Oh, for fuck's sake!" I muttered, then moved to straddle him. Even with my tits in his face, and the heat of my pussy radiating against his skin, he remained motionless.

"Suck my nipples," I ordered. 

Gavin was the picture of reluctance in bringing his mouth to my breast. A deep moan escaped me as he began tentatively suckling. My resentment all but evaporated, and I wove my fingers through his hair. Horniness made my hips start moving, and I gently worked my pussy against his dick.

His mouth grew more eager once he switched to my other breast, and his fingers tugged and twisted at the nipple he'd just pleasured. It had grown freakishly elongated from his attention, and I found I enjoyed the pinch he delivered to my flesh.

"Rub my clit," I whispered.

While noisily sucking my tit, he sought out my pussy. Finding me soaked, he made a contented sound from low in his throat. I trembled beneath his expert touch; the way his fingertips at first only fluttered over my swollen bud had me whining for more.

But Gavin let my nipple escape his lips so he could murmur, "This has gone far enough, Mandy."

"I'll say when it's gone far enough! Now, keep playing with my pussy."

Our eyes locked as he applied increasing pressure to my clitoris. My muscles tightened and then relaxed, only to tauten again. I couldn't resist the urge to grind my cunt against his hand. 

"Such a bad girl," he groaned, breathing faster with me. "I never knew you were such a conniving little whore."

Those words, even more than his fingers, made me come. The air was suddenly stripped from my lungs, and though my lips parted, I could make absolutely no sound. I could only shudder on his lap until he had to plant a steadying hand against my back.

His touch grew merciless, almost unbearable, and I finally squealed while trying to writhe away from him. 

"Where you going?" His voice was low and mocking.

In response, I pressed my lips to his. He tensed and started to withdraw, but I held him fast. Still quivering, I opened my mouth, and his tongue instantly worked its way inside. 

Forced to break the kiss and catch my breath, I searched his face. For a second, he looked ashamed of what he'd done. It was his remorse that aroused me most of all.

Grabbing his chin, I forced him to meet my eyes. With an angelic smile, I said, "Don't worry, I'm not going anywhere."

It was now or never, I knew. Doing my best to appear confident, I lined my pussy up with Gavin's dick. His erection pulsed in my grasp, as if in warning. 

"You're not ready for this." Tilting his head back, he gave me an entreating stare. 

I merely snickered. Already, I was realizing that bravado and horniness made for a dangerous combination. But there was no turning back now.

Gingerly, I sank down, allowing that bulbous cockhead to press against my opening. Fuck, it was even thicker than it looked! For a single horrifying instant, I was afraid it wouldn't fit. Biting my lip, I kept trying to work it inside me.

"Wait," Gavin said. 

Now, I was willing to listen. When he took hold of his cock and slid it along my folds, I had to fight back a moan of relief.

"You're good and wet." His voice was strained, and I noticed the heat in his gaze. "We shouldn't let all that lubrication go to waste. Of course, if you need more..."

"I don't!" I snapped. 

Once he was back at my entrance, I made every effort to relax. This would hurt, I told myself, at least at first. But I still wanted it.

Finally, my flesh yielded enough to accept his tip. The unrelenting pressure made my eyes widen, and my legs gave an involuntary shudder.

To his credit, Gavin didn't mock me. Instead, he caressed my clit with the pad of his thumb. 

"Oh, God!" I'd broken into a sweat, pain and arousal creating a potent cocktail inside my bloodstream. I lowered myself down another inch, hissing from the way his meaty shaft stretched me. When Gavin's eyes again locked with mine, I sensed he was struggling to control himself. Did he long to thrust his hips? Or maybe he wanted to grab mine and make me take his entire length.

Though I began panting like a sick animal, I refused to stop. Moving lower still, I felt the pressure from his erection within my core. He was so damn hard, so firm against my tender inner walls. At one point, I opened my mouth as if to scream, but only a pitiful groan emerged.

The man clearly wasn't a sadist, for my discomfort did nothing to excite him. "Alright, Mandy, we've fucked," he said. "You got what you wanted—"

I shook my head. "I haven't. Not yet." My features twisted into a grimace just before I took the last inch of his dick.

My legs were no longer supporting my weight and holding me aloft, but they continued to quiver. Gavin sighed while sliding his palms over my thighs. 

"Let yourself get used to it," he gently urged.

I released a giggle that bordered on hysterical. "I feel like I have two cocks inside me right now."

With a crooked grin, he asked, "Is it too much?"

"Almost," I confessed. "But not quite."

Leaning forward, I winced at the slight change in position, but the fresh twinge of pain didn't keep me from kissing Gavin. He gathered up a fistful of my hair, holding me fast while claiming my mouth.

"And how does it feel, being inside me?" I whispered against his lips.

"So fucking good!" He planted kisses on my neck, his teeth and tongue conveying his hunger. "I know I should feel guilty, but you didn't leave me much choice, Mandy."

Sitting back up, I thrust my tits in his face. "Oh yes, you're absolutely blameless here."

In response, he gave my nipple a playful bite. The sensation coaxed me into moving my hips. By now, the throbbing in my cunt had subsided to a dull ache, and I was brave enough to slide my slick flesh along his erection.

Gavin let out a pleasured groan, his stare fixed on our joined bodies. "That's it, baby, ride me!"

Need edged his voice, and when he cupped my ass in his large, strong hands, I let him guide my rhythm. I was still panting and covered with sweat, but I felt euphoric in my triumph. I'd done it! I'd taken Gavin's massive dick and was now striving for my own satisfaction.

Our sighs and moans, and his occasional grunt, competed with the sound of the rain outside. I dared to increase my pace, and even as my pussy clenched in protest, I gripped Gavin's shoulders and rode him faster.

"Ah, fuck!" His jaw tightened, and I heard him suck in a breath through gritted teeth. "Look at you, bouncing on my dick like a filthy slut!"

My body betrayed me, offering up another orgasm. While my back arched and my muscles contracted, I allowed myself to scream. Though I was too full, too stretched, my pussy did its best to milk Gavin's erection. The sensation made him gasp. 

"Oh, it gets you off when I tell you what a little whore you are!" He laughed at my weakness. "I think...
