My Sexy Cousin!!

A chat with a chum on xHamster about his interest in family images. I talked to them about my cousin and her part in my sex education and life. I hope they won't mind me adding this to my posts about my earlier awakenings.
I had a girl cousin, Rosie, who I was very close to in age and we used to play together, while one or other of our Mums went shopping or whatever. We were close in age, she was about a year older, but we had grown up almost as twins. One time, I would be 12 she 13, I was at her house, up in her room, when I decided to take my clothes off, so she could see me naked, as my boy chums did regularly. I was at the boys school, were we'd done sex in biology almost at the start, but they hadn't done it at the girls school, so she was excited to get the full gen about the birds and bees. We sat face to face on the floor, and by now, as you might expect I was massively hard and putting on a good show!!
I explained the basics of sex as we had been taught, of cock and fanny, spunking off, etc, all in the correct biological terms. I added some extra detail about wanking but explained I only knew things from the text books and diagrams, and just wondered, innocent like, if I could see the real thing!!
Completely unexpected, Rosie offered to strip off as well, there and then, so in a moment we were both stark naked. Her bush was beginning to show (mine had yet to really grow) but as she at on the floor facing me, she eased her lips apart so I could see her entrance. She pointed out the little bean of her clitty (this was new to me, the biology lessons were just that, the egg, sperm, penis and vagina, etc, only basic diagrams without detail!) and how it made her feel very good if she rubbed it. One of her friends had obviously learnt the ropes (the friend had a horse as I remember, so knew and felt things the other girls didn't!!) and had told Rosie how to jill off with a hairbrush. I then told her about my friends wanking, sucking and buggering each other (see earlier posts) and as I had such an achingly hard cock, I asked if I could put my put it in her, to try if for size so to say. She wouldn't let me on board (we didn't have a johnnie and of course she was obviously scared of getting preggers, I'd obviously explained things too well!!!) but did offer to let me wank in front of her to show her the male side of mastubation. I said I would if she did, so there we were jacking and jilling for all our worth, when all of a sudden, she leant over and grasping my cock, pulled me really hard.....she'd only managed three or four strokes before I knew I was getting to my vinegar stokes. Years of hard training with my chums kicked in and I patted her head, our usual warning of impending ejaculation, only to feel her tug even harder!!! I really think if I hadn't coated her hand with man custard, she'd have pulled the bally thing off!!! I groaned as I emptied my balls over her hand and the floor, at which she just laughed and finished jilling herself to an orgasm even I could see and share in, watching her young body shudder and shake!!! We cleaned up, my cock, her hand and the carpet, dressed and went down for tea with my Aunt. My cousin whispered that she'd 'forgotten' to put her panties on again and was commando beneath her shortish skirt!!!! She laughed again as I went red and had to use a plate to disguise the fact the front of my trousers now resembled the tents we used in the Scouts!!!!
Sadly, we didn't get any opportunity to repeat the games again (even though I managed to knick a rubber off my Dad!) until some years later, when she introduced me to the pleasures of smoking (see that post, Rosie's the friend therein who would drink, then smoke then wank me!!) and we continued our friendship over some lingerie shopping, sex toys and a few wonderful, memorable weekends!!
