i read all those mom's tummy stories, so for me when growing up, it was my half sister, same father just different mothers, and me, and our uncle, when she reached puberty at age 10, she grew breasts and had one hot body, after her first period at 11 years old, our uncle started sleeping with her and she just loved the attention our uncle had given her. almost 2 months after her first period, i was 11. two years later when she was 13 when i was still 12, she came up to me in panties and training bra and asked "did uncle tell you?" i said "tell me what?" she happily said "come feel uncle's baby." i put my hand over the front of her panties when she said "keep feeling, i love how you rub me." my dick got hard. at the time she was 13 in '97, she was part of this dance group, she was in her fourth month of pregnancy and was just barely beginning to show when she was on stage with 5 other girls, the dance costumes were bra tops and short shorts, the dance lasted just 2 minutes. the 5 other girls were age 13 and were all sexy slim and when their short shorts came one inch below their belly buttons, showed 5 or 6 inches of flat tummies, my sister's short shorts, with a just barely noticable tummy panel stretched well over her just barely there baby bump also way over her belly button, so she bared only 2 inches of not quite as flat tummy between her bra top and high waist short shorts. my uncle and me were at the dance show, when all 6 girls were on stage dancing in sexually arousing moves, my sister's barely there baby bump was a stand out, i got real hard in the dick just watching her pregnant tummy gyrate, her hot sexy little ass too, she even felt her then growing tummy in those hot little short shorts a couple times while dancing, lots of guys were turned on by her too. that was her last dance recital also because she was pregnant. more than a month after her last dance recital, her tummy grew, she was not shy about baring her then growing tummy on the beach in the same dance costume, the bra top and tummy panel short shorts, she'd danced in for her last dance recital before quitting for her then pregnancy, her nearly round tummy got the attention of high school boys and college guys too, they had big hard dicks in their speedos, i walked along the beach with her, i was hard in my speedo too at age 13.
