When I was in high school my mom worked as a bartender and my dad would go to the bar to be with her almost every night she worked, including weekends.

One Friday or Saturday night they were gone as usual, my little sister had a friend over, both were about 14 and I was maybe 17. I didn't have any gas in my truck so going somewhere was not in the cards.

We were downstairs watching a really racy movie on HBO. I got a rock hard erection from it and I guess it showed. Shauna, the friend (very hot girl) got up to get a drink and when she came back she plopped her very nice ass right down on my hard cock and laughed. That got everything that follows started.

I lifted her off of me and told her that if she sat there very long I would cum in my pants. SHe told that I should just take them off then, so I did. My cock bounced off of my belly when released which made the girls laugh. Shauna wiped the pre-cum off the head and my belly and ate it which didn't help my situation any,

I told the girls I wasn't going to be the only one naked so they stripped off as well. I was used to seeing my little sister naked as we never wore clothes moving from the shower to our rooms when the parents were gone and we had watched wach other masturbate a few times. Shauna didn't have much for tits but had a very nice bush. My sister was about a 34C then but not much bush or ass.

Shauna dropped into my lap again, then raised up and slid my cock into her very wet pussy. I almost lost control but managed to withhold cumming. Shauna started bouncing up and down and moaning and when I glanced over to my sister her fingers were buried in her cunt.

After a few minutes I said I was going to cum and Shauna raised up and released my cock which started shooting cum in the air all over Shauna. I got out from under her and started cleaning her up, with my tongue. I then heard my sister moaaning and looked over in time to see her squirt out a stream, I went back to Shauna and finished the clean up and started eating her out, her first time for that she later said. But I was then sirprised to feel lips on my hard cock. Yep, it was my sister. I tried to stop her but it was no go, she kept on sucking and said that fucking was out of the question but oral was ok as far sa she was concerned.

Since she had talent at it I just ler her continue. After getting Shauna off a couple times and cumming in my sisters mouth I then ate her out while Shauna worked her cunt.

After we had all came a fer times we got dressed as my parents were due home in an hour or so. This was the beginning if many a night spent fucking and sucking each off. My sister always told mewhen Shauna was coming over so I would be sure to be home.
