"What are you doing?" Julie asked, almost screaming.
"Chill out sis," Beth responded, "We both want this and it isn't against the law or anything. Besides he licks pussy like no one else I know." She added almost laughing.
Julie just stood there for what seemed like hours before she spoke. "Well I think it is kind of weird, I mean we do call him Dad after all, but I won't say anything if you include me.
Beth and I were both taken back with the last statement, but I knew what Beth was thinking when she looked at me and smiled that smile I know so well.
"Well come on over and join us." Beth said, "Don't be shy now."
Julie walked over to us and stripped her clothes off. She wore a black half bra beneath her shirt and a red thong came into view when she lowered her shorts. My cock sprang back to life as I watch Julie strip. Beth told her sister how this had all come about and Julie added that she felt like someone was watching her sometimes. She actually laughed and said she was glad to find out the truth and that she was right about her feeling of being watched. I just watched in amazement as Julie continued to strip, her tits weren't as perky as her sister's because they were a little bigger and her pussy wasn't completely shaved but was trimmed nicely.
"Julie do you remember what we used to do when we were younger?" Beth asked her.
"You mean when we explored each other a couple years back?"
"Yep, that's what I mean, get over here and let me try again." Beth said, a smile spreading across her face.
Julie spread a towel on the deck and laid back, spreading her legs slightly. Beth knew what she wanted and crawled on her hands and knees toward her sister's crotch. Beth gently bent down and licked at her sister's pussy. Julie responded and moaned while playing with her tits. Beth continued to lick at her sister and her ass was held high. I stood there in shock watching them do something that they had done many times before. Beth stopped and looked back at me, she wiggled her ass and asked if I saw anything I liked. I grunted and moved toward her. I got on my knees and buried my cock deeply in one thrust, making her gasp with delight. She turned her attention back to her sister's pussy and I began to slowly fuck her from behind. I held her hips and picked up the pace of my thrusts. Beth was built for this position and I matched her perfectly. I thrust faster and harder into her and slapped her ass several times. Beth continued moaning, partly from my cock and I am sure partly from her sister's juices. Julie began to squirm and I knew she was close to an orgasm. Beth's pussy tightened around my cock and I knew that she was also close to cumming. My own climax approached quickly and I began to take short quick thrusts into Beth's tightening pussy. All three of us came at the same time; my cock shot its load deep into Beth's pussy while her pussy tightened around me. Julie laid there squirming and her mouth was open in a soundless scream. Beth fell away from me, my cock making a pop as it came free from her sloppy wet pussy. Beth and Julie laid close together and shared a kiss, their tongues intertwining.
I rolled into the pool to try to recover and heard a splash behind me. I turned and watched as Julie got into the pool and Beth moved over to the pool edge. Julie then moved between her sister's legs and began to lick my cum from her slit. Beth sat there at the pools edge and half reclined with on hand on her sister's head and the other playing with her nipple. From the look on her face I could tell that Julie was doing a great job licking Beth. I moved behind Julie and fingered her slowly causing her to moan. My cock began to harden again and I soon found myself sliding my cock along her wet slit.
Finally my cock hardened enough and I slid into Julie slowly. I began with slow long strokes, determined to make it last. I held Julie by her hips and continued to thrust into her slowly, using all my length, almost pulling out, then thrusting back in completely. I continued this pace for 5 minutes until I felt Julie's pussy tighten around me. I laughed to myself, thinking how both of the girls were the same. Both of their pussys tightened around my cock and I knew their climax was close at hand. I thrust deeply into Julie and shot my load, she responded my moaning loudly into her sister's pussy, sending her over the edge. Beth bucked against Julie thrusting her back again onto my cock causing her to cum hard as her pussy tightened around my cock once more.
I was totally wasted and drained and floated back to the deep end. Smiling broadly as I floated there, I wondered how much of this I could take and if it would ever end. I floated for 20 minutes then finally decided to get out of the pool. I swam back to the ladder end and watched in amazement as Julie and Beth were locked in a hot 69. Both of them moaning and licking, trying to make the other cum first. I told them I was heading inside and they replied a muffled ok.
My mind was totally lost as I climbed into bed with my wife, she didn't even stir and I didn't have the energy to try to wake her. I lay there and my mind raced at the memories of what happened tonight and believe it or not my cock began to twitch again......
