Her grandma would take her on a special trip to the grocery store the day before in preparation.During the course of their expedition, Liv often grew ...ored with searching through endless pebbles in her pan and would wander off to explore nearby meadows and pine forests. Mitch always joked that Liv was bad luck when she was in the stream. Every time she returned they would usually have a large gold nugget to show her.For a while, Liv bought into the idea that she might be jinxing their. In confidence, I asked her if she knew wither her sister was a virgin and what the secret would be in seducing her sister.Well, they look at each other, grinned and asked to come back to there place with them and they will show me some nice tricks to try.To make a long story short, after a few hot 3some sessions with them, it works, I was able to seduce and fuck my, yes still virgin, girlfriend.Even though I was now fucking my girlfriend, I was still seeing her sister and husband.One hot summer. I realised that sex was a subject not far from the surface whenever these two were together. Uncle Charlie replied by saying no but telling Sam that I was good at nibbling foreskin on Uncle George and sucking his cock and would Sam like to see me performing on him. With that, Uncle Charlie dropped his trousers to reveal his prick which was already semi-hard. Sam then said "You can save your blow job for later. Let's see what fun we can have with him today - I'm sure we can make him come enough. Then another. I feel myself opening receptively."Tell me what you want big sister" I want... I want you to penetrate me!" Oh Yes? Would that make you happy?" MMM Hmmm!"The fingers withdraw and I feel Cindy getting herself situated behind me. Then something is pushing against my back door."Ask for my cock..." I want your cock Cindy. Fuck me with your cock.... ooooooOOOOHHHH!"She sinks it slowly into me, pulling out a little and then pushing farther in."OOOOhhhhh!" I squeal in a high, breathy.
