We were halfway home when Jen said, “Pull over, down that side street.” I pulled into a shady lane near our house. No one was around, and Jen unbuckled and leaned over. I gasped as she tugged at my bathing suit and freed my dick. I lifted up to help her move my swimsuit down, and she engulfed my dick in seconds.
“Still salty,” she commented with a giggle. I leaned back, letting her suck me off. I cupped one of her bare tits in my hand, my eyes constantly checking the mirrors. No one turned down the road, but what would they see if they did? Jen bobbed faster, sucking me as I gently squeezed her breast in my hand.
She suddenly took me in her hand, stroking me furiously as she kissed the base of my dick. I came, gasping and stifling a grunt as I ejaculated into her hair. She laughed, still stroking me as I came on her face, now taking me back into her mouth, swallowing what remaining cum spurt out of me. I was spent, exhausted, my dick quickly softening. She sat up, buckling up. She had cum in her hand and on her chin, which was slowly dripping onto her tits. Strands of cum hung in her wet hair. She wiped her chin and grinned, sitting back as I drove home.
When Mom came home we got dressed to go out and celebrate Jen’s job. Both women wore sundresses and sandals, and I wore slacks and a dress shirt. Both had their hair up, and their dresses showed their ample cleavage. Mom took us to an open-air restaurant on the beach, near where I had fingered Jen that morning. She pulled out all the stops, treating us to a celebratory dinner for Jen. The wine flowed freely, since I was the designated driver, and soon both my mom and my aunt were tipsy.
“Here’s to Jen,” Mom said, raising her glass, “now she can buy her own groceries.” She giggled, touching her glass to ours. They each took a long sip of wine, and I took the moment to stare at their tits. Mom caught my eye and grinned as she set her glass down.
“Thank you,” Jen said. “For everything. For letting me stay here, for helping me out, for loaning Will to be my personal servant.”
“You have to share him, though,” Mom joked. I shifted in my seat, wondering if she’d be so amiable if she knew that hours earlier Jen was showering my cum out of her hair. I looked them both over. They were both so open about their sex lives when they were together, I wondered if they’d really mind all that much? It sure beat sneaking around.
I thought of my mom laying on me that morning, my dick touching her pussy. I had let her choose, but I had made myself clear. I wanted it. I wanted her to want it. Would it work again?
“Tell me,” I said in a low voice. They both leaned in to listen conspiratorially, “Did you two pick those dresses together?”
“Why?” Mom asked.
“Because our waiter has come by more than usual, and he’s been sneaking glances down them.”
The sisters grinned, and Jen said, “unintended side effect. You get used to it.”
“I don’t think I could ever get used to it,” I said.
“Good,” they said together, giggling.
We headed home, Mom and Jen in the back seat, both a little more than tipsy. We made it into the house and they headed straight out back, dragging me with them. Mom pulled off her dress and threw her bra on the chair, running to the hot tub. Jen followed suit, her body jiggling pleasantly as she ran. They beckoned me over, both of them giggling and blushing. I slid into the water, both my mom’s and Jen’s eyes on my dick as it disappeared under the water.
