Amanda, Katie, Megan, and Betty had one hell of a vacation. The girls were pretty much the center of attention their whole summer vacation. They got lucky on a few occasions with some of the local beach hunks, who were although not quite as strong as the girls provided some much needed sexual release.

Their families couldn't figure out how all four girls were growing so big all at the same time. Their families suspected they were taking some kind of growth hormone or something, but they were unable to find anything to prove it. Near the end of the girls summer vacation they entered a bodybuilding contest in which Amanda came in first, Katie second, Megan third, and Betty fourth. This made the other contestants very upset as they had trained all year for the event and the four new girls of course had an unfair advantage.

When the girls came back to school they turned quite a few heads with their bigger stronger tanned bodies. Megan was 6'9 with huge muscles, Betty was 6'11 with muscles almost as large as Megan's, Kattie was 7'1 with breasts the size of watermelons and biceps the size of soccer balls , and then there was Amanda 7'0 tall with muscles larger than any of her friends and breasts only surpassed by Katie's. As the girls walked down the hall to class every person staring at them kept wondering how much bigger are they going to get.
