Basically, from a month or so i have been assigned a young colleague to teach. Her name Is Asja, a 24 girl with 3 daughters and an ass that looks like drawn. We spend most of our 8 hour shiftsl togheter,so we go beyond work talk and indulge into some chit chat. Lately, we started exploring a Lil more private sides and turned out Asja Is unsatisfied with her sex life, having "a sweetheart by my side but without the Great fun". We go on our days talking and teasing each other. Some years ago i stole a Key of and old dining room turned storage, and most times go there to have my dinner (evening cafeteria sucks), turns out that every evening Asja joins me, and we started to use that 45 Min break to relieve ourselves. Most of times,it's a helluva blowjob. She likes to cherish and make a huge mess with her saliva, doing everything to make It last,swallowing my load and indulging into sucking everything clean. Some times we go for some bareback quickie, and She usually bites on something to help her hold her moans. A few times,She also squirted all around the floor. Why am i confessing now? Because tonight's the night i Will gift her with a buttplug, so She can have that inside whenever She pleases, a reminder that only my Dick Is allowed to go in there....
