After supper mom and I walked down to the pool and smoked a doobie, and she explained what an orgy was, then asked if wanted to attend one tonight. Wh...n I said yes she got excited and called for everybody to come down to the pool. As they came down the stairs they were stripping off their clothes and jumped into the pool naked. We had a wall of windows but there was nobody but family around for miles, so who have a fuck.Mom took off her clothes and then took off my clothes as I stood there. That was how he found her when he came into the kitchen for a drink. Watching her, watching her arse wiggle, he felt that all too familiar sensation course through his body. Then he noticed that she wasn’t wearing any underwear at all. Not even her usually gstring under her summer dress. Forgetting his thirst, he grabbed her hips and pulled her back onto his now rigid organ. Feeling his hard cock pressed into the crack of her arse, Fran stood up, pushing herself back into him. She took his. She was groaning loudly as she played with my cock, telling me that she wanted to fuck me but it would look bad for her if she did that on the first night. I wasn't even disappointed as I was still enjoying this tremendous wank. She kept going, running her hand down, making sure my balls were lubed up as well as she crabbed them between her fingers. Suddenly I felt this amazing feeling coming. I'd never masturbated previously to this so this was something I hadn't felt before. It kept building. This made me feel really strange but I finished my first task with enthusiam. I filled her with heaps and she moaned a thank you.Then I turned my attention to my next task.I took younger sister laid her down on the bed knelt beside her and commenced my treatment on the most lovely set of breasts ever seen.They were firm ( even virgin like) with beautiful nipples.I fondled them both ran my tongue over and around each nipple in turn. Her smile got bigger and bigger even more so when I started to.
