We hadn’t planned on sharing a tent, but when we got to the site and grabbed the gear, we found out her sister had left all the poles behind.
I said “no worries,’my tent is huge and you can crash with us.”
The day was spent at the lake and all day my sexy ex was teasing me in her skimpy bikini. He sister noticed us flirting and I won’t lie, looked pretty hot herself.
We had setup the tent with her sis on 1 side and me on the other. My ex between us both. Her sister turned in early. We got to bed an hour or so later after drinking some more at the fire.
We laid down and hopped under the covers. She was wearing her underwear and a tiny tank and just grinned her ass against me. I was instantly rock solid and pulled my cock out. I went in for a tease of her pussy to see how wet she was and realized she was ready to go. I pulled her panties down to her thighs and slid right in.
Her sister was sleeping with her back to us, we were both in our sides and I was sliding in an out. She let out some moans so I took my hand and covered her mouth. Simultaneously I slammed my cock in deeper. She began to match my strokes and push back on me. We tried to avoid making the clapping sound and waking her sister up.
After a couple minutes she began to gyrate faster. Rolling her hips in my cock. I could tell she was about to cum. She took her free hand and grabbed my ass and pulled me deeper into her soaking pussy as it began to pulsate into a deep powerful orgasm.
She stopped and relaxed, my cock still hard, sittting in her tight pussy. She pulled it out, pulled the covers back and went down on me. I couldn’t believe her! Here we are with here sister a foot away and she has my cock exposed in her mouth(granted it was dark).
I was so turned on I knew I was going to cum hard. She worked my cock with her mouth and hand. And she loved swirling her tongue which really got me going. She tickled my ass with her free hand, and that sent me over the edge. It felt amazing! I began to spasm and release a stream right into her mouth. My eyes closed as I felt my release.
I relaxed, my gf slipped out the tent to go to the restroom, and as soon as the tent closed all I heard was, “my sisters a lucky girl.”
I looked over, and realized her sister had rolled over because we woke her up. We were giving a show and I had no idea!
The next night before bedtime we all laid down and her sister said, “keep it in your pants tonight.” My gf and I just froze …….. but we now also both knew we loved exhibitionists.
