It was now March and spring was definitely in the air. The weather was gorgeous. He had "Basket Case" by Green Day down cold and I opted to begin teaching him a couple of AC/DC tunes, "Highway to Hell" and "Dirty Deeds." He was able to knock those down in fairly quick succession and I moved him on over to "Black Dog" by Led Zeppelin to try to stretch his ability further while also making him memorize all the major and minor pentatonic scales in all positions. We would usually play for 4-5 hours a day and, increasingly, he was eating dinner with me rather than his family. Because he was quickly improving on guitar, doing well in school, getting laid basically anytime he wanted and was squiring around one of the hottest girls in town, let alone the school (i.e., me), he was beginning to develop a bit of a swagger. Other chicks on our campus picked up on that and, coupled with me openly sharing the praises of his oral and penile skills, he was getting a hell of a lot more female attention than he did only months earlier. Moreover, because he was with me a lot, he could be more selective about who he talked to. That lack of easy availability boosted his attractiveness even further.

What may have added to that mounting self confidence was my pleading one day that he be rougher with me in bed. I asked him to spank me hard while he fucked me and to not just talk dirty to me, but to call me names. He took to that stuff like a fish in water and even began insulting me in public (albeit when nobody else could hear us). For example, when we met up in the morning for the walk to school, he sometimes said, "good morning my little slut." That made me so wet that I would wish he would throw me down on the sidewalk and rape me right there. He would tell me, "as soon as we get to your house, you'll get your mouth on my dick," and shit like that. He also started skullfucking me, something he never even tried to do before. It was like a new facet to his personality was manifesting itself after he had been keeping it under wraps or he didn't know it was there. It made me much hotter for him. I wanted to become his slave, but he was really too young to own another human being yet. I'm not sure he consciously even realized what he was doing when he denigrated me. I did warn him that he better not get carried away with it because there are limits. In fact, one afternoon in April, after he had dealt me a particularly fierce rutting, he asked me if I was mad at him. I replied in the negative and he reacted by referring to me as his "good little slut." I could only giggle because the characterization was accurate.

In the wake of that, he would slap my ass hard as we made our way to school, which also made me wet, or he would pin me down in bed and tickle me until I was breathless. I suspected at some point he would go after my asshole and so I bought a tube of Astroglide and some condoms just in case. Anal wasn't, and still isn't, my thing, but there was nothing I could do about it if he decided he wanted it because he could just overpower me.

Now it was no secret that teens look at internet porn. Kevin didn't at my house because I didn't have a pc first of all, just a couple of laptops I used. I wondered if he looked at any BDSM material. I wasn't sure I wanted to suggest that he do that at his age.

On June 3rd, he had his 15th birthday. When he came over to pick me up to set out for school, I was totally naked when I let him in except for a big red bow I tied around my hips. "Happy birthday, honey!" I bubbled before hugging and kissing him. I handed him a card, which was enclosed in an envelope. He opened the envelope and read the card. "For You," it said on the front and, when he flipped it open, he read the words I had wriitten earlier in it: "I give to you for your birthday all of my love. May I please be your girlfriend?" "Woah," he exclaimed. He threw his arms around me and passionately kissed me. "You're the most awesome girlfriend ever!," he assessed, smiling. "Now suck my dick," he firmly ordered. I went right to my knees and swaddled his cock with my lips and tongue. He was already hard, having probably turned to stone when he saw my nude state. He placed his hands on either side of my head and reamed my mouth and throat with his battering ram until he drained his balls into my belly. "That's a good slut," he approved. "Now hurry up and get dressed." I had already prepared an outfit, a white sundress, white panties, white pantyhose and strappy white heels and, once I had disposed of the bow,  hurriedly pulled everything on. I held on to his arm as we ambled toward our campus, my head on his shoulder.

When we got there, we still had about 15 minutes before class started. We sat on part of a long bench near one of the classroom buildings. He pulled my shoulder into him and, with his other hand, slid his fingers up and down my thigh, feeling the material of the nylons. "You look so awesome, babe," he critiqued. "Thanks sweety," I answered. He kissed me softly and then we gabbed about nothing in particular before we had to piss off for our respective classes.

When I met him for lunch, I confirmed something that I hadn't really paid attention to before: he had grown a couple of inches over the past several months. When I first met him, he was my height. Now I was looking up at him. His cock was also a full six inches. He was still a few inches shorter than his dad, so I wondered how tall he would end up being.

On the walk home from school, he turned to me at one point and said, "you know what I want for my birthday?" "No honey, what is it?" "I want that ass," he disclosed with a wicked smile, grabbing a handful of my butt cheek over my shorts. "Ewww," I refused. "That would be really painful and disgusting," I went on. "Yeah, but you're my good little slut and you're going to give it up," he asserted. As soon as he uttered that phrase, the lubrication faucet in my cunt activated. I giggled nervously and held his arm tighter with mine. "I knew it," he chuckled.

When we transgressed the threshold of my front door, my stomach became unsettled due to what was ahead. "Get your clothes off and lay on the bed on your stomach," he commanded. He went to the bathroom and, after I stripped, I pulled the lube and condoms out of a drawer in my nightstand and left them on top of it. He came into my bedroom and removed his clothes while I lay there waiting to see what he would do. He saw the Astroglide and Trojans and snarked, "you're prepared. What, were you in the Girl Scouts?" he cracked. ""Or the Slut Scouts," he added. I laughed.

What I didn't know was that he had been reading up on how to do anal on the net and actually had gotten ahold of his own lube and rubbers. He brought them into bed with him when he kneeled between my open legs and then I felt some of the oil being squirted into my anus. He slathered some on to his now sheathed dick. I knew I needed to relax and made my body go limp. I then felt him trying to push the head of his penis through my tight pucker  He managed to pop it in and I felt his soft but still firm cockhead inside me and then the sensation of it burrowing into me. It hurt. A lot. I writhed and squealed while he buried it all at once inside me and he held it there to allow my back channel to become accustomed to the invasion. It felt like my anal walls were spasming around his fuck stick. "Fuck, this feels epic!" he enthused. Very gingerly,  he started withdrawing and then re-entering my fudge tunnel and his gasps told me he was likely to do so again in the near future. He squirted more lube on to his shrouded length every now and again as the frequency of his thrusts picked up. All I could do was lay there and take it. Was I enjoying it? No. But he was, and how!  "God, you're such a dirty little slut, letting me fuck you in the ass," he growled with a pleasured sigh on the end of it. He grabbed my hair and whipped my head up as he pressed his spear through my backdoor time and again, letting me know he was taking me and not endeavoring to make love to me. That made me really hot and I began moaning. "Shit, you are a slut, aren't you? You're loving my dick in your ass, aren't you?" I didn't answer and he slapped my ass real hard. "Yes!" I blurted. "Yes, what?" he countered in a mean tone of voice. "I love your dick in my ass!" I agreed. This bit of submission ratcheted up my horniness further and my pussy was positively sloshing with moisture. "You're going to give me this hole anytime I want it, aren't  you?" he demanded. I unconsciously spluttered, "yes Master!" which I didn't mean to say, but it just came out. He began pounding his flesh spike into me harder and faster as the compression from my sphincter on his manhood passed through it until he probably grunted loud enough for the neighbors to hear through the closed windows and jetted spurt after spurt of his spunk into the tip of the condom.

He laid on top of me with his dick still inside me for a couple of minutes before it shriveled and retreated from my asshole. "What do you want me to do with the condom babe?" he wondered. "Just flush it," I advised. "And then wash your hands and cock so you don't spread E. coli around or give me a nasty infection." A few minutes later, after he had gotten rid of the rubber and cleaned his hands off, he jumped into bed with me. My anus was already feeling some soreness. He looked down on me. "You okay Misty?" "Yeah, I'm just a little sore," I revealed. "You don't hate me for doing this, do you?" "No honey," I cheerfully denied. "I thought you might want to do this somewhere down the line, but I love you and like how you treat me." "I really liked it when you called me 'Master'" he averred. "I want you to call me that from now on," he directed. "Yes Master," I permitted. "That's a good little slut," he smiled.

"Suck me slut," he suddenly barked. I guess me consenting to call him "Master" made him hard and now he needed to vent his balls again. He sat upright against the headboard of my bed and opened his legs. I scooted up on my belly and licked up and down the length of his reinvigorated snake while I nuzzled his balls with the fingernail of my lefthand's index finger. "Ohhhhhhh shit," he moaned with a little bit of a shudder. "You give the best head, babe," he favorably critiqued. I invited his root into my warm, moist mouth and bobbed my head up and down as he moaned and groaned away. He stroked the back of my head while I was attempting to get him off again after he had just fucked my asshole, which was now throbbing and stinging from said invasion. I swallowed the full six inches and he got to enjoy the sensation of his meat being squeezed by my esophagus again and again until he announced he was going to cum and poured what had been left in his nuts on to my tongue. I gulped his cum down and climbed on top of him. "I love you, Misty," he sighed warmly, pulling me tight against his body with his arms. "I love you, too, Master."

"You really like dominating me, don't you Master?" I guessed. "Yeah, I guess," he responded rather blankly. "I love it when you do, Master, but don't take it too far and respect my limits, okay?" "No prob Misty. I'm just having fun with ya."
