Jenny was f******n and had not only discovered the joys of masturbation, an urge brought on by her starting her periods, but the added spice of lettin... men see her do it, and in return, watch them shoot a load in her honer.Being able to induce a man to wank off was a trait all teenage girls aspired too, myself included, though O had progressed to giving hand jobs, not to boys but to older men, in fact my most daring was to get naked and rub my pussy with their cock, teasing myself by wetting. I’d caught a glimpse of his weapon at the outset. He was only our age but it was like a man’s. My Jonathan was second biggest but there was a quantum leap to this great thing. I wondered why he always wore such loose trousers. He quite casually dropped them, and his pants, and sat down for the job. His balls were huge, and immensely hairy. But his cock, well …. a heavily veined and muscled beauty which made all the others look immature. My dress was still a little open, and he. I could see the outline of her cunt. I couldn't be sure but it looked as if she was shaved."What are you doing?" She sounded slightly irritated."Sorry sis, I was just deciding if I needed to heat the oil up again." There was a quick "No" from her.As I continued with the massage I smiled to myself. What I should have said to her was 'I was just admiring the shape of your cunt and imagining how good it would be if I could finger you'.I was now working on her upper thighs, just below the hem of. I pinned her to the bed and flipped her over. Then I lifted her ass into the air.Shreya: Damn…how did you know this was my favorite position?I smacked my neighbour’s daughter’s ass and it bounced hypnotically from the resulting shockwave.Me: From the way you threw your ass against his cock repeatedly while he fucked you raw.Shreya: Mmmm..so you did watch all that, huh? Well..go on.She pushed her ass up further and I licked my finger then lubricated her pussy with my saliva. I smacked her ass.
