“Would you coach our moms’ volleyball team?” asked a teammate from my mother-in-law’s team when she came over to our house! And right in front of me, she changed into her tight, form-fitting uniform! Huh! Bloomers these days? I was surprised, but I couldn’t take my eyes off that plump butt. Then, with a suggestive smile, she moved in close and pressed her bloomer-clad butt right against me! So sexy! Way too sexy! What is this magical power of the bloomers?! Plus, the fact that I could see a little bit of her panties peeking out was even more arousing! Ahh, I can’t take it anymore—I can’t resist! I want to touch that butt, I want to squeeze it! I’ve completely fallen into my mother-in-law’s trap and am sinking into the quicksand of bloomer sex… A *** in gym shorts and a grown woman in gym shorts are completely different! That voluptuous butt flesh about to spill out of the shorts! The prominent bulge of her butt cheeks… it all drives a man wild! If I can see such a sexy sight up close, I’ll be their coach—or whatever—in a heartbeat!
