My sister was still at home for now, but after my Birthday, she would also go away for University, and it surprised me how it made me feel. I couldn't...put my finger on it back then, but looking back now, it sure was the end of an era for me.On Sunday the 10th of September, my mother had organized a surprise party for me. Well, I had reached the age of 18, and I was now, legally, considered an adult.I was of course happy that I had turned 18, because it would open up a lot of things to me that I. She said she will come from the next day and do the job properly. I could not sleep the whole night and was desperately waiting for her. She came at around 11:30 am and knocked and within no time I opened the door and she was surprised. I asked her to come in and start the job.She came in with a pleasant smile and asked me where the kitchen is to which I moved my eyes from her swaying ass to her face and escorted her to the kitchen moving closely with her and that aroma. Oh god, that was damn. I was good friends with a guy named Greg (not his real name). We had known each other about 10 years and we would often go fishing when we had some time away from the girlfriends. Being that we'd been fishing so many times he had pissed in front of me, his cock was uncut, something that I had never had.We made arrangements to camp near a lake for a weekend. It would be a weekend of fishing and drinking. We got to the lake after work Friday and set up our campsite. After hanging and drinking too. Ken feeling her ass give way a bit, ploughed into her with reckless abandon. Watching his python thick cock sliding in and out of Erica’s puckered ass encouraged Ken, and he was at the point he wanted to be to try an experiment. Allowing his cock to pop free of Erica’s bung hole, Ken drove it back into her cunt for two strokes, then repeated the two stroke beat in her shitter. Back and forth he went, ass to cunt, cunt to ass, till Erica was screaming in rapture beneath him. Fireworks shot off.
