Mary is approximately five-seven with a slim, willowy but womanly figure. As near as I could tell through her loose uniform, she had small breasts and...a tight, compact ass. Mary has red auburn hair that she almost always pulled back and hid underneath her uniform cap. It appeared to be braided, although I didn’t know how long her braid was because of the cap. She has green eyes; a turned up nose and generous full lips.A week before Christmas I gave her sealed red envelope. The envelope. I relaxed for a couple of minutes watching the girls wanking and checking out the porno and was surprised how soon I became hard again. Katie was the first to notice."Fucking hell, Nick, that was quick. I suppose I should offer you my panties this time so you can have some more fun. I'll just have to go home commando with some spunky panties in my handbag."With that she stood up and removed her black silky panties and handed them to me. Unlike my sister though, Katie didn't watch the movie once. I slowly gathered myself and asked the question,"How long?"She sniffed, wiping her face, "what" her voice whimpered again."How long have you been cheating on me?" I said in a calm low voice.Her voice began to tremble as I felt her shuffle slightly in the bed "um, well .... the thing.." How long?" I asked raising my voice. "Six months" her voice broke. That statement hit me like a ton of bricks. My chest tightened and my grip on the golf club loosened. Six months?! How fucking stupid have I been. I have fucked 9 girls till date including this married girl. Let’s call her Vandana (by the way, it is not her real name).So it all started in Oct 2019 when I received a DM on Instagram from Vandana. She had seen one of my comments on a reel that was related to wildlife and human encroachment and was impressed by that. About Vandana, she was 28 (at that time), a bit dusky girl, 5’6, and quite fit. She lived in Bangalore with her husband and used to work there.Anyway, the conversation started.
