This saw the beginning of a regular arrangement (for want of a better word) between Charlie and me. She would go out on Thursday night and turn up at my house at some point for a roll in the hay and to stay the night. I think she looked forward to it a great deal. She is actually quite committed to her studies, so she does not really have time for a boyfriend. However, she is also a horny little minx, so she needs a good fuck every so often to release the tension. I presented a good alternative to a boyfriend as I gave her what she needed (a body for sex, an ear for venting and shoulder for condolence) without asking anything of her outside of when she wanted me. I must admit, I think she sometimes considered the sex to be a form of rent for my time or for a place to sleep that did not require her to walk home, but even then I was not going to argue.
Over time I came to know what I termed to myself the three stages of Charlie drunkenness. These aligned almost perfectly with when Charlie turned up at my house. Level one was between zero and three on a scale out of ten. I came to know this as the Girlfriend Stage because Charlie would act like we were in a relationship. She would turn up between 9.30pm and 11.30pm, tipsy at most. If it were earlier she would generally want to talk to me about a problem, often with school work. If it were later she would probably have been out, but just not interested in getting drunk. These nights generally involved us watching TV, with Charlie snuggled up against me until she finally pulled me off to bed.
The Girlfriend Stage resulted in gentle caring sex with lots of foreplay, especially a lot of breast play. I'd try to make Charlie orgasm a couple of times with my fingers, tongue or even one of Emma's vibrators. We then had slow, tender sex with lots of kissing and eye contact, generally in the missionary or cowgirl positions (or even in spoon if we were feeling very lazy). This type of sex did not tend to get Charlie off (hence why it is important to make her climax during foreplay), but I really think she enjoyed the closeness. The look of satisfaction on her face when I finally came in her was wonderful. We always fell asleep with her curled up against my chest and my hand cupping her breast.
The second level of drunkenness is what I have come to term the Randy Stage (between four and seven out of ten). If Charlie turned up between about midnight and 2am she would be fairly inebriated (our first night together would have been a six) and have only one thing on her mind: getting ploughed. In other words, the mode of our interaction on those nights generally resembled our second night together, with a few variations. She would always start by turning up at my door and sticking her tongue in my mouth. Sometimes we would not make it to the bedroom, with her demanding that I take her immediately, bent over the couch or on the table. Interestingly, that only ever happened when she was wearing a skirt. I do not know if that meant she dressed based on the sex she wanted or modified her behaviour based on her clothes.
However, normally Charlie headed quickly for the bed, leaving a trail of clothes behind. I must say it was pretty arousing watching her backside disappear around the door, with her already topless, after she had just pashed me. By the time I caught up to her I generally had just enough time to finish undressing her before she quickly instructed me on what sexual acts she wanted. Sometimes she had me eat her out until she came and then roll her over and fuck her as hard as I could, resulting in an even bigger second orgasm. Sometimes she wanted to ride me, sitting astride me while she furiously rubbed her nipples and clitoris until she peaked. I found that extraordinarily erotic so stopping myself from cumming early was a challenge. Thankfully I quickly learnt Charlie's tells so I can quite successfully culminate with her.
The third regular in our Randy Stage rotation was my favourite. Charlie would push me back on the bed and throw her leg over my head putting us in the 69 position. While I attacked her juicy little clam with my mouth, Charlie would grab hold of my cock and gently work it with her hand while giving the tip occasional licks and kisses. Her aim was to just keep me hard (I do not really think it is a problem, but I do not complain). My aim on the other hand was to get her off. When she got very close (I could tell because she got very still and forgot what she was doing with my member) she would lift herself off my face, slide down my body and impale herself in the reverse cowgirl position in one smooth motion. The first time she did this I was quite surprised, expecting her to just climax on my face. It generally took about two bounces on my cock before she arched her back with her face towards the ceiling, let out a shriek of pleasure and had what she assured me were some of the most powerful orgasms she ever had. She then collapsed forwards onto my legs. I generally ejaculated as she climaxed through shear erotic thrill, but if not I slid out from under her, pulled her legs apart and had my way with her as she lay flat on the bed in a daze. I do not think she actually knew what I was doing after she came, but she did not seem to mind.
The final form I have dubbed the Smashed Stage (eight to ten). Thankfully I have only actually seen this once. Apparently Charlie's friends had taken her out drinking for her birthday and she had not held back. Consequently I was woken at 3am by her hammering on my doorbell. When I opened the door she fell on me as she had been leaning on it. She was babbling inanely about how drunk she was, that she liked Jagerbombs and even one passage that I interpreted as "Yous has the most wonzerful cock." I was not particularly happy, I must say. I thought my days of looking after drunken teenagers were way behind me, but what can you do? I made her drink some water, got her a bucket in case she vomited, stripped her and put her in bed. While I was taking her clothes off she kept making lude statements like "I'vez been thinking about you all night, I wanted to fuck you onz the dance floor," and "I love your big fat frobbing dick in my cunt." When I pulled her underwear off she blurted out "Arez you going to has your wicked way wiz me?" and then giggled. I assumed it was the booze talking. I certainly was not in the mood having been woken up so late. Pulled the covers over Charlie and turned off the light. By the time I slid into bed next to her she had fallen asleep and I assumed that was the end of it.
I must say I did underestimate her stamina. Being woken up by having a dripping wet teenage pussy being lowered onto your face is a unique experience. I was surprised for a second or two before Charlie moaned from above me "It's my birthday and I'm so horny. Please make me cum" before grinding herself on my nose. By the sound of her voice and the positioning of her body I could tell her was kneeling over my head, holding onto the headboard of the bed. I reached up, grasped a buttock in each had and went about my task with gusto.
I think she must have been playing with herself for a while before she decided to use me because she was very wet indeed. I decided this was not the time to play games so I grabbed her clit between my lips and pulled the little nub into my mouth, sucking as hard as possible. Charlie went wild. She stated thrashing around on my face, thumping the head board with her fist and screaming "FUCK, FUCK, FUCK." Then she froze, her whole body tensed up, she grunted "AAAAAAH. YES!" and then toppled off me sideways.
I was shocked, but what I did know was that I had a raging hard-on that needed to be quenched. I rolled on top of the nigh on comatose Charlie, hooked her legs over my shoulders and sunk into her I one push. I was so aroused I came within five strokes before collapsing back onto the bed and fell straight asleep.
When I awoke I was not sure the events of the previous night were not a dream. I was only convinced it had happened when I slipped my hand between the legs of the still sleeping Charlie and found my semen drying on her inner thighs. With that came my recollection that Charlie had mentioned it was her birthday, and then a bolt of inspiration. I quietly got dressed and rushed down to the major shopping centre and into the biggest lingerie store just as they opened. I picked out a cute little black lace demi-bra and thong set in Charlie's size and preferred brand (I had checked the ones she was wearing) and got the shop girl to gift wrap it. I raced home, wrote "Happy Birthday, XXX" on the tag and left it on the bedside table with the normal provisions.
Charlie for her part claims not to remember even leaving the club, let alone walking to my house or anything that followed. However, when I got home that night there was a note on the bench that read "I love them. XXX." I'm happy to say those undergarments do make regular appearances at my house, especially for the Girlfriend Stage when undressing is more of a game. I do not know if that is Charlie trying to please me but I do not mind.
These Thursday night liaisons made up the bulk of my engagement with Charlie. Really, the only sign that she was ever at my house was a towel in the bathroom that I kept for her and a pair of her underwear that she would leave in my washing basket so that it would be clean for her the next week. We did see each other at other times as later stories will attest, but generally we were both just a convenient source of sexual and emotional fulfillment for each other. Neither of us wanted anything more so it worked perfectly.
