Karen was very conservative when it came to her sexuality. She had told me that she never really had a real boyfriend. She was the complete opposite o... the girls where they bend over and you see miles of thong or cleavage gushing out. She was never into wearing reavealing clothes of any sort. I got a decent look down her shirt every now and then though when horsing around. She reminded me of a proper lady, like a Southern Belle from the olden days. One day it was after school and it was just. I followed him to his place near by and we went up to his bedroom on the second floor of the town house. We got naked and sucked each other to hard erections. I started fucking his ass with my almost 8-inch dick and he let me know that it was the second biggest dick he had ever taken. I’m pretty gentle as I want my partner to enjoy the fuck as much as I do. He was a bicyclist with a really hard ass, but I was the one riding him. After I came, we got dressed and headed down the stairs. He. The lights were off in the room, but I could make her out in the light coming in from the dim hall way light."How ya doing?" I asked casually."I don't know." Oh?" Tony?" Yeah?" Am I behaving okay?" She asked seriously."Yeah. You're fine. Something bugging you?" I don't know." Okay if I come in and sit?" Sure."I went over and sat on the edge of the bed towards the footboard and offered her a sip of my beer. She sat up against the headboard and took the beer and had a swallow and handed it back. My jealousy flared, and it all came to a head before the third week was over, when I accused her of allowing her relationship to have gone too far. ‘I guess you know then,’ she stated bluntly, hardly a trace of guilt in her voice. ‘Of course I do,’ I pretended with a growl, my mind reeling at what perhaps she was about to reveal. ‘I’m sorry honey, it just happened,’ she sighed. ‘When you go to work in the morning, Joss slips into our bedroom.’ Shit! Bad enough but it was about to get worse..
