Heading to the bathroom, Amy and I spent most of the time snuggling, before the door was pulled back, and I saw my mother naked for the first time in years. She was… gorgeous. Just an older version of Amy. Smaller breasts, wider hips, but she clearly looked after herself. Thicker hair above her pussy than her daughter. She bit her lower lip nervously, Amy offering her hand. “Come join us, Mum. Nothing to be frightened of.”
“This isn’t weird?”
“Mum, people will think Mark and I being together is weird. You wanting to join us in the shower is nothing compared to that.”
I was rock hard again and with Mum between myself and Amy, my cock was soon brushing up against her, which earned plenty of laughter from her. “I have a beautiful daughter and my son definitely has a big cock,” she said.
Amy swapped placed and figured she’d shown off by dropping to her knees, taking her cock in her mouth. Mum smiled as I moved enough that she could stand by to my side in the cubicle, noticing her watch in amazement as my entire cock disappeared into her mouth and throat. “I love sucking his cock, Mum,” she murmured.
“I can see that, baby,” Mum replied softly, “She’s good, Mark?”
“She’s wonderful, Mum.”
“Do you want privacy? I can…”
Amy took her hand. “Stay, Mum. Watch your children have fun.”
“Want to finger yourself again?” I whispered into her ear. Mum smiled and kissed my cheek. “I’d like to watch you properly.”
Mum smiled again but turned to lean back against the wall, her fingers immediately moving to between her legs. Watching my mother masturbate was something I never thought I’d see in my lifetime, one hand caressing her breasts, the other between her legs. She was mesmerised by her daughter blowing me, clearly turned on by it, and it was little wonder she actually had an orgasm before I filled my sister’s mouth. Once she’d swallowed and sat back, Mum needed a tight hug, holding her to my body. “This should feel weird but it doesn’t,” she whispered.
“We’re having fun, Mum. As you said, we’re all adults, open-minded. So don’t worry about it. Helps my mother is as hot as my sister.”
That made her lean back, her face clearly surprised. “You think that, sweetie?”
“Mum, you’re fucking gorgeous,” Amy replied on my behalf.
She sighed. “Thank you, both of you. Now, I’d better actually get breakfast ready now.”
Leaving Amy and I alone, she started to giggle. “Well, I’ve just sucked my brother’s thick cock in front of our own mother. It felt… so naughty but I’m so turned on now.”
Turning her around, I held her tight to my chest and fondled her until she enjoyed another orgasm, then we finally washed down and stepped out. Breakfast was nearly ready by the time we were done, Mum putting the finishing touches to some bacon and eggs, a pot of coffee and tea in the middle of the table. Once she was sat down, I walked around to the back of her chair and leaned down, undoing the tie of her dressing gown. “Are you naked under there, Mum?” She nodded wordlessly. “So that means I can see your pussy again?”
