My twin sister knelt beside me for a moment, pretending to pick up something on the floor. ‘I’ll cover for you at home JD’ she whispered as she ...tood up again. I gave her a weak smile and mouthed the words ‘thank you’ as she headed out the door. I love my sister. No matter what happens I know she’ll be there for me. The door closed behind the last student with a click and the noise in the hall gradually died down until all I could hear was Miss Dolly looking over some papers and the beating of. Her shirt had come open during our scuffle, and her ratty cutoffs had both come open and had fallen partway down her slim thighs. She had absolutely nothing on underneath, and I took in that first sight of her nude body like a castaway drinking rainwater.Her breasts stood proudly on her chest; softball sized globes capped with pinkish brown nipples tightly bordered by like colored areolas. My hand covered her sternum and half of her left breast, with my thumb a half inch from her left nipple.. She grinded back and forth letting out soft moans and rubbing his chest."awwww, abby i'm too hard i need to take it out, i cant take it any more." As she inched back down towards the end of the bed he tits jiggled and bounced around. she had a proud grin on her face knowing she had got her brother so hard. abbys then kneeled there examining her brother crotch and watch with lust as be slowly revealed his dick to her.....she was pleased to find a rock hard throbbing cock,that had to be at. After a couple of months into this relationship and one day she asked us to go out for the night somewhere because she wants a romantic night with him and to show what she has packed in her panties. As you can imagine we were delighted for her and agreed to go to the cinema and then have a dinner together.While we had gone to the cinema they had been eating their dinner and talking lik normal about random things. After about 30 minutes they went to watch a film on the TV which was very short.
