I could what I wanted to her without anyone looking. I looked at beautiful body and the nice amount of cleavage she let show through her shirt. Her uniform was identical to mine with the exception of the knee high socks.. Walker decided he didn't want to hold anything back now either. He lunged at me with his kisses and starting rubbing my hardening cock through my jeans, causing me to moan.

Kellie knows how big my cock is????????” Kellie grinned at me again... and I felt her eyes going down my body to my crotch.... at which point I felt myself getting a ‘stirring’....“So? I’ll ask you again. What do you think? Do you like the colour? Are the bra cups a bit on the deep side? Come.
