But as they continued to have these naughty encounters, Alexa realized the reason was the size of Derek's penis.Stroking it nice and slowly, Alexa sta...red at the big thing. It was quite simply the largest penis she had ever jerked off. It seemed so out of place on Derek too, him being a skinny band geek. Her dainty fist couldn't even completely close around its girth! It was fascinating to touch and look at."Does my hand feel good today, Derek?" Alexa whispered."Y-yeah." Derek breathed out,. But with her brother's help, she tried a few combinations and her locker door opened. Some clothing exchange still meant she would be naked for a few seconds while she returned her brother's pants and socks and then got into her own clothes ( minus panties, of course. )It had not occurred to her to put her own jeans on first, before removing her brother's shirt. She just undressed and then did the exchange. Oddly, Victor had not stopped his twin sister from stripping naked in the hall. Perhaps. There was a faint aroma of pussy in the air. She was thick with juices and dripping. She wandered if he could smell it too.Finally he put a finger under the elastic of one panty leg. She closed her eyes, and felt his finger probe her pussy lips, first the outer lips and then the inner. Finally the finger entered her wet and throbbing cunt hole and she moaned loudly.“Ohhhhh, ohhhhhhh, I can’t stand it, oh, please, Frankie, please!” She gave his cockhead one last swab with her tongue and pushed. “Dan has always been able to undo a woman’s bra with just two fingers,” Karen joked, getting a laugh. Her bra fell to the floor, revealing her petite, firm tits. Tiffany kissed Dan as he began to pull her skirt down, it fell to the floor. She was now fully naked and put her arms around his neck. Their heart rates increased. Dan admired her young, teenage body.Her small mounds stood out firm, and he could easily count her ribs that supported a flat stomach. Tiff’s hip bone and pubic bones.
