It has been a while since our cute female cousin came over to play at our house! Although she still likes her older brother even after becoming a high school girl, she knows it's not appropriate to touch him so she resisted temptation until he showed off his hidden gym clothes, which were designed to tease and seduce! My cock couldn't handle the sight of her round, jiggling ass in those tight, revealing workout shorts anymore; I had to grope her firmly! As my throbbing dick rubbed against the fabric of her panties, we engaged in a passionate encounter that combined both innocence and lust – all thanks to those irresistible gym clothes!
