I felt Grandma moving next to me. I opened my eyes, in time to see her naked ass walking away out of the bedroom. I sat up and swung my legs off the side of the bed, when I heard Aunt Bridgette admonishing my Gram.
"What the hell are you doing, walking around the house starkers?" "The boy will be up soon and you need to put on..." Aunt Bridgette didn't have a chance to finish her sentence as I walked out of Gram's bedroom, just as naked as her.
"Ro, tell me this is some sort of joke." "Why is he coming out of your room like that?"
Gram answered, "Why would you think a handsome younger man would be coming out of my room naked?"
My aunt looked from my face to Gram's and back again. "Ach no. Ye didn't boff the lad last night?" "Ro, he's ye grandson. There's a name for that."
"Aye, and you'll not be saying nothing about it." Gram told her.
In the meantime, I had slipped up behind Aunt Bridgette. My arms encircled her from the back and my hands went right for her big breasts. I started nuzzling her neck and planting tiny kisses. My fingers found her, surprisingly, small nipples. I started pulling gently on them and flicking them.
"Boy, what are..No you can't..Oh my gracious. That feels so good."
"Want me to stop?" I asked.
"I know I shouldn't..but feels so."
Suddenly, something happened that I had never seen before. Aunt Bridgette started shaking and her breathing became ragged. She came just from my playing with her nipples for a few minutes. I turned her around and as she faced me, I could see a growing wet area on the front of her nightgown. I kissed her hard, nothing like a nephew should, my hands dropping to her abundant buttocks, kneading and massaging them.
Looking over her shoulder, I asked Gram "What time is our flight?"
"At three this afternoon." She answered.
I turned Aunt Bridgette around and started to direct her to the bathroom. We entered and I took the hem of Bridgette's gown and started lifting it upward. She made a half-hearted attempt to push my hands away, but Gram stepped in.
"Bri, just let him. You won't believe it."
She stopped trying to push my hands away and just stood there. I lifted here gown up and as I reached her breasts she lifted her arms to let me take it all the way off. In the meantime, Gram turned on the shower and adjusted the temperature.
My hands roamed over her naked body. Standing behind her I started to kiss and tongue her ear and the sensitive nape of her neck. I massaged her bare ass, my hardening cock sliding between her cheeks. Aunt Bri started moaning from the sensations. I scrupulously avoided touching her sex, so as to heighten her anticipation.
I gave Aunt Bri a gentle push toward the shower and after she stepped in, I followed. I was stunned when Gram joined us. We all soaked down and Gram and I took washcloths and soaped them, then Gram started washing Aunt Bri's front as I started on her back. As we soaped her up, she started moaning. As we worked downward, she opened her legs to allow us both access. I told her to reach back and spread her ass cheeks. As Aunt Bri complied, I slid the cloth through her crack. The touch of my hand against her tight little knot caused her to gasp suddenly. I returned to kissing her neck, allowing the hot water to run down our bodies.
Gram asked with a deeper voice than I'd heard before "How's that feel, Bri?"
All Aunt Bridgette could do was moan, from the sensations of Gram and I were providing. As I looked on, Gram moved toward Aunt Bri. She was standing so close that their bodies were touching. Gram looked into her eyes and moved in kissing Aunt Bri hard on the mouth. I saw Gram's mouth open and her tongue force its way into Bri's mouth. Gram's hands started touching Aunt Bri's tits, massaging and squeezing them. She was running her thumbs over Bri's hardening nipples.
The visual of my Grandma, getting to second base with her sister was incredible to me, since she hadn't gotten laid in years, until last night. I reached around Aunt Bri's body and hefted her tits, taking them out of Gram's hands. Gram leaned over and took one of her nipples into her mouth, suckling like a newborn and lapping at her breasts. Aunt Bri's head was thrown back and she was breathing hard.
I suggested that we adjourn to one of the bedrooms, as they had more room than the shower.
The three of us went into Gram's bedroom, where this all started. We helped Aunt Bri down across the bed. Gram and I lay on either side of her. Gram was working on one nipple with her mouth as I took care of the other. My hands slid down her body until I could feel her curly bush under my fingers. All the while, Bridgette's breaths were coming in short gasps. I slowly started to kiss my way down her soft, somewhat pudgy belly. I was leaving a damp trail with my tongue, along the way.
I heard Aunt Bridgette "Ach Ro, what's he think he's doin?"
My Gram lifted her lips from her nipple and told her "Just let it happen, luv. Trust me, you'll love it."
I kept working my way down, finally arriving at Bridgette's thighs. They were positioned just at the edge of the bed, so I slipped to the floor. I gently applied pressure to her knees to open her legs. Aunt Bri gave a start and looked at Gram. Gram just looked back and nodded her head. Aunt Bridgette finally relented and allowed me to spread her chunky legs apart. I lifted them and starting at her ankles, I began kissing up her leg. I took my time to allow her to enjoy every touch of my lips and tongue. When I got to it, I kissed her gray haired puss and started working my way down the other leg, just as slowly.
Finally, when she was ready, I knelt between her legs and opened them further. I spread the cunt hair away from her prize and moved in. I started kissing her, already damp, lips. I heard her exclaim. " What does he think he's..."
