From the shore we heard a woman’s voice, “Ding. Round two,” Beverly giggled at that because we were in round two as well. Moments later we heard, “AAHHH… AAAHHH.. AHHH. Jesus Frank. Whatever’s gotten in to you, I like what you’ve got in me. Fuck me Frank. AAAHH… AHHHH…AHHH.”
Beverly took the cue and started rocking her hips forward and back. She didn’t have the strength to push up with her thighs like Eva had done. Her motion was working just fine for her and me. She got herself in the same rhythm as our shore bound partners and joined the refrain, “AAAHHH…AHHHH… AHHH.” The stereo effect got Eva laughing. Then Eva moved over and began sucking on Beverly’s nipples and to my surprise Beverly held her there. ‘Eva is making headway with her big sister,’ I thought.
Beverly was sliding on and off my cock and I could feel my balls boiling. I hoped that Beverly was close too because I really wanted to get her off before I came. The “AAAHH.. AAHHH’s from shore continued in synch with Beverly’s. I was building and only moments away as I humped up my body preparing to launch.
With Eva held tightly to her breasts, Beverly started with a low-pitched growl that built to a scream at the same time the woman on shore screamed, “Jesus Frank. You’re…killing…meeeeee. Oh gawwd…I’m… cumming… again.” Beverly didn’t announce anything; she just exploded in to her orgasm and screamed out hard. Her pulsing pussy pulled me over the top and I unloaded in her. I groaned hard with each pulse of cum and Beverly softly screamed as she received them.
As we settled down, another male voice down the shoreline called out, “Hey Margorie! I think its bedtime.”
Eva pulled back off her big sister’s nipples and said, “I think we have fans. It’s a good thing we’re leaving in the morning. We’ll have every husband on the lake dragging his cock across our deck.”
Beverly giggled at the vision and said, “I’d like to stay and see that.” Beverly scooched her butt forward, pulling herself off my softening cock. I could feel cum ooze out of her pussy and onto my stomach. She wrapped her arms around my neck and stretched up to kiss me, pressing her big tits into my chest. Eva joined her as I alternated passionate kisses between them.
Eva quietly said, “I have your number and you have mine. If you’re ever back in the city, I wish you’d call me. Come by my office. I have this fantasy about getting fucked on my desk.”
I replied, “I’m certain that there’s a long line of guys at work with the same fantasy.”
Eva giggled. “I’m sure that’s true but there’s no way any of them have half the cock you have.” She reached behind Beverly and picked up my soft, sticky cock and squeezed it. Beverly kissed me again and pushed herself back down my thighs until she could get her feet under her. She bent low to suck in my gooey cock as her face went by. It reacted to her mouth and she cooed. Eva nudged Beverly and said, “Come on sister-of-mine. You can dream about Jack’s big cock all the way home tomorrow.”
Beverly released my rising cock and gently bit the velvety crown as she giggled again. She stood up as Eva handed her clothes over. Neither of them put them on. It was too dark for anyone to see them anyway. I moved my naked body from the bench seat to the captain’s chair and started the motor. It was barely audible at idle speed and I heard a woman’s voice from the shoreline, “Goodnight Jack. Stop by anytime. I’d love to have you.”
