Chapter Three: Public fun with Sister
Sis decided she wanted to go to Sonics for supper. I pulled on my shorts as Amy slipped a sundress over her head. She didn't have panties on. Sis put her mini skirt and halter top back on as well. At Sonics, after we had placed our order, Sis asked Amy when the last time she had fun with her mother was.
"Last night." Amy replied. "Mom licked me until I got my orgasm, then I watched her play with a dildo until she got her orgasm and we went to bed." I slid my hand into my shorts as the attractive waitress skated to the car with our food. She winked at me as I pulled my hand out of my shorts to take my coke from her. As we ate, Amy began to describe watching her mom having sex with her boyfriend the previous week.
"Yeah. Jeff took me and mom out to Shoney's, and then after we got back home, Mom wanted me to go to bed, I did, but I wasn't sleepy. I didn't hear Jeff leave. They were laughing about something, so I went to see what was going on. He had his hands inside of Mom's shirt, playing with her titties. After a while, Mom pulled her shirt off, and Jeff took her bra off. He sucked her titties for a while, and then he pulled Mom's pants down and stuck his fingers into her pussy. He made Mom sit down and he licked her pussy. After Mom came, she opened Jeff's pants and started sucking on his cock. It was so big!"
The waitress skated back to the car to see if we need anything else. I had my hand in my shorts again, and didn't pull it out that time. The girl smiled at me as she left. I wondered if I saw her nipples poking out in her shirt.
"Did they do anything else? Asked Sis. I leaned back and fondled my growing penis, remembering that it had been inside Amy and was sucked off twice earlier in the day. I had attempted to jerk it off several times before, but it became chaffed and sore after two times. I had tried again for the third time a couple of weeks ago with the same results back when Mom wasn't at home that day and I roamed the house naked.
Amy drank her coke, then continued: "He made Mom sit on his cock and bounce on his lap, like I did to David, until she got up with his cum running out her pussy. They kissed for a while, and then he dressed and left. Mom was still naked, and his cum was going down her legs when she came down the hall. I jumped in bed and pretended to be asleep when Mom looked in my room."
The waitress skated back to the car, after I had pulled my penis out a little, to collect our trash. She saw what I had done, licked her lips and winked at me.
It was dark when Sis stopped at a roadside park, but there was enough light to play by, so we went for the swings. Sis pushed Amy and I on the swings until I tired of the swing and jumped off at the height of its momentum and sailed through the air briefly to Amy's delight. Sis caught my swing and began to swing herself. I watched them for a few moments as the air pushed their clothing up showing their bare pussies. Amy stopped swinging and ran for the slide as I spun on the merry-go-round. Her sundress was hindering her slides, so she pulled it off and slid down naked. I had spinning glimpses of Amy's naked slides and Sis's up-skirts. Sis's halter became untied, and she pulled it off. On my next revolution I saw that she was topless. Her nipples were bobbing up and down from the momentum of the swing.
I stopped pushing the merry-go-round and let it spin down to a slow stop. Amy came to the merry-go-round and wanted to ride. So I spun her around for a while, then jumped on it and pulled Amy to the center, and had her to sit on my penis as I laid there luxuriating in the feel of her tight pussy sliding up and down the shaft of my penis until I came. The merry-go-round had slowed its revolutions again, as Amy got up with my cum dripping from her pussy onto the merry-go-round.
Sis had stopped swinging and was sitting there peeing into the sand. Amy saw what Sis was doing, and wanted to try peeing standing, so Sis stood behind her and reached down to Amy's pussy and showed her where to spread and hold the lips of her pussy so the pee came out instead of running down her legs. Amy was more successful that time.
I felt I had to do a little more than pee, so I went to the edge of the play ground, and released my bowels as Sis saw what I was doing and brought some napkins. After I cleaned up, Sis wanted to go get some ice cream. She told Amy and me that we don't have to dress, as it were completely dark then, just get into the car. Sis re-tied her halter, but left her skirt off, and drove to an ice cream store's drive thru. She told us not to show ourselves after she ordered.
We went to the window, and the cashier leaned out to give Sis her change, and noticed that Sis was bottomless. A few moments later the cashier returned with the ice cream without her t-shirt and asked Sis to wait until the end of her shift, and give her a ride home, and they'll have fun together! I noticed the cashier's nipples were tenting her bra. Sis laughed and told her maybe the next time.
Amy and I finished our ice cream and I had Amy to lie down in the seat while I crouched on the floor of the car and began to explore Amy's pussy again with my fingers and tongue. Amy enjoyed the chilly sensation of my tongue on her clit, and I liked the feel of her pussy warming my tongue up.
From the vibrations of the car and my tongue motions, as I tasted the remnants of my earlier cum and her tangy pussy juices, it was not long until Amy began to cum into my mouth while she giggled in delight from the waves of euphoria washing over her nude body, fanned by the nighttime air rushing over our skin.
Sis watched us with a smile in her rearview mirror, as she drove bare breasted, for she had pulled her shirt off at a traffic light a while back. She was fingering her pussy and close to cumming when she pulled the car over to the side of the highway and came around to the back. "Lick me off." Sis begged me.
I clambered out as Sis laid herself across the hood of the car, and I began to eat her warm, moist, ice cream coated pussy until she came with a scream of delight as a couple of cars whizzed by. My penis was throbbing, and dripping precum heavily as we got back into the convertible. I asked Amy if she wanted to lick the cream from it, and she grasped my swollen penis eagerly and sucked it vigorously as I stroked her hair from her head.
My excitement has been building for a while, so it did not take long to cum into Amy's mouth. This time she didn't let go of me, and hung on until my penis finished it's spasms within her mouth. She then rose up and swallowed the cum and wiped her lips and chin with the back of her hand, as Sis pulled the car into the driveway of her home.
