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.
