.." I said trailing off in the end."I know, but I can't help it." he said and reached for my PJ-pants and pulled on them, trying to get my ass into fu...l view."Can you take them off so I can have a better look at you?" he asked, almost pleading.I blushed but slowly stood up and took off my PJ-pants before sitting down on the couch again, now only in thongs and a tank top. I could feel how my nipples started to get hard and it showed through my tank top which Tomas also noticed when I had sat. Once the lights dimmed, I started sneaking more looks out on the crowd and am pretty sure that I was spending more time checking out the pretty women around me than I was paying attention to the concert. So many hotties, so many milfs, so many girls dancing and grinding on their men and other women. One woman caught my eye, she was clearly older, a true milf. Maybe 40 45, she was about 5ft 6in with brown hair past shoulder length, fairly slender, long legs, nice ass and big tits, not 36 DDs but. She invested a lot of time, money, and effort into maintaining both.It was easier to maintain the wardrobe than the body, that only took careful shopping, good taste, and money. The body, on the other hand, required steady exercise, long hours at the beauty salon for manicures, pedicures, skin conditioning, more time at the hair stylist, then careful maintenance every day.It helped, of course, that she was, unarguably, undeniably, absolutely beautiful.Her face was soft, the contours carefully. "Coward," giggled my sister.They double teamed me, sucking me to a full hard. Then Frankie said "As of ten minutes ago, I was sixteen years old, Tut. Wish me happy birthday!" Happy birthday," I panted. "Sweet sixteen and been kissed a lot!" I grinned.Calmly, she stood up, climbed on the bed like it was a couple of steps, and straddled my hips."Sweet sixteen and never been fucked," she said, her face completely serious. "Guess what I want for my birthday, Tut."I know I must have looked pretty.
