Thankfully she let me have my fun and didn't tell my Mom. It was a shock for her and all of us when her husband left her when I was about 18- I could ...hear her tell my mom what a slut the new younger girlfriend is and how she probably “let's him do all the dirty stuff he always goes on about”- I spent a while wondering what that dirty stuff could be. I noticed around then that she started dressing a little differently- shorter skirts and lower cut tops showing off her big tits. I could swear she. I was a little supprised but had been with guys before so wasn't shocked.I asked him would he like to go for coffee and he could tell me about the phone as it was too busy here to get service.I ordered some coffee for us but we never talked about the phone just about eachother. He had only been with one guy and never a girl but had really liked the guy but had moved away.I told him I had been with a few but liked women and couples best.I asked him back to my place which was only 10 minutes away. I knew that she and I wouldn't be fucking because my penis was so small (compared to her black boyfriends cock especially), but I'd gotten quite used to that, and I wasn't expecting her to 'return the favor', so to speak. I'd masturbate later on perhaps; but for the time being, all I really wanted was to keep licking her pussy, and to have the chance to clean up every last drop of that other guys sperm!Eventually, Tara and I traded places, and she straddled her pussy directly over my mouth as I. As we got back to camp we went into the rear area of a barrack block that we knew was totally empty , and before I could say jack rabbit I had his cock in my mouth and I sucked him off good till he shot his hot load down my throat and I swallowed the lot , he said knew you were like me a cock sucker , then he shagged my brains out then I returned the favour.Next day he looked sheepish he asked me what happened last night I said I can’t even remember getting back.
