Once nude, we stepped in and let the warm water cascade over our bodies.
“You’re very handsome, you know,” I said as I grabbed a bar of soap and began rubbing it all over Peter’s chest.
“Thanks, Mom!” Peter said, watching my hands work their way down to his crotch.
I lathered him up all over, spending lots of time on his ass, his hardening cock, his arms and chest. It became foreplay to love-making.
When I was done, I rinsed him off, knelt, and started sucking his cock. Once it was fully erect, he pulled me up for a deep kiss.
He took the soap and started washing my body, lingering over my slippery nipples, and my dampening pussy. He ran his hands up my ass and washed me there too. I was getting majorly turned on by this point.
He stood behind me, grabbing my nipples from behind and grinding himself against my ass. He lifted his cock and held it to my slit, rubbing back and forth. He even put his dick in my ass crack and moved it up and down.
“Ooh!” I said, pushing back. “You’re giving me an idea, Peter – something your dad and I used to do in here.”
“What’s that?” Peter replied, still moving his dick up and down.
“Oh, I think you know,” I said. “I’d love it if you’d fuck me in the ass like your dad used to! Have you done that before?”
I turned and faced Peter, who nodded.
“I may have fucked Delia and Kat that way!”
“Oh my!” I said. “I can picture you shoving your dick into your sister’s ass. So sexy!”
“She loved it!” Peter said.
“Well, I love it too. Why don’t you reach into the top drawer of the cabinet right next to the shower and grab the lube in there.”
Peter grabbed the tube. He turned me to face the wall of the shower and began to rub lube all around and in my asshole.
“Mm,” I said. “Looks like you know what you’re doing!”
“Delia taught me well,” Peter said.
“Your thumb feels good in there,” I said. “Get some on your dick and put in me!”
I leaned over and put my hands on the side of the shower. I felt his dick sliding up and down my crack. He put pressure on my asshole with the head of his dick, and I felt it pop in.
“Ooh!” I said. “Keep going!”
He pushed in a little more and I felt my ass expanding to receive his cock. The lube made it very easy for him to slide in and out.
“Your ass is so tight, Mom,” he said, pushing more inches of his dick inside me.
“I know,” I said. “But it feels so good. I can really feel it when you stretch me out. It’s incredible!”
Once he got all the way into my ass, he started pulling out and pushing in. He cupped my breasts as he fucked me, and I reached down between my legs and rubbed my clit.
“Oh, Peter!” I moaned. “It feels so good for you to fuck me in the ass. Oh, so good. Keep going. Push harder, Peter. Fuck, yeah!”
I started pushing back on his dick to get it as deep as possible. My pussy was wet, and my clit swollen. Peter tweaked my nipples and every time he pushed in, I could hear a slapping as his crotch hit my butt cheeks.
“Oh, shit!” I said. “Don’t stop. Keep fucking me. You’re going to make me cum, Peter. Oh, fuck!”
“I want to cum in your ass, Mom!” Peter said as he sped up.
“Me too!” I said, starting to moan. “Oh, mm, oh, mm, ah, oh!”
“I’m cumming!” Peter cried out and shoved his dick as deep as it could go.
“Fuck, I’m cumming too!” I cried.
As I came, I felt Peter’s dick get bigger and could feel his cum spurt out even more than in my pussy. It aroused me so much I came a second time on his dick.
Peter pulled out of my ass after he was done pumping cum into me. I turned and we kissed and made out in the shower for a while, until the hot water started to run out!
“What a day!” Peter said as we cuddled on the couch later that night.
“A day of firsts, that’s for sure!” I said, massaging his upper thigh. “You know, there was something different about you when you came home. It brought back feelings I hadn’t had in a long time. Same with Kat.”
“So I hear,” Peter said.
“Wait!” I said. “You know about me and Kat?”
“Kat told me all about how you masturbated in front of her,” Peter said, grinning. “I’d have liked to have seen that!”
“Oh dear!” I said, remembering how embarrassed I’d felt, at first anyway.
“I’m glad she pursued you, Mom,” Peter said, touching my leg. “Sounds like you two had some wonderful lovemaking together.”
“Oh, we did, and still do, in fact,” I said, picturing Kat’s mouth on my pussy. It was getting me wet just thinking about it. “My visits to your sister’s apartment are amazing!”
“I’d love to watch you two sometime, and even participate?” Peter said.
“I think that could be arranged, as long as the twins aren’t around,” I said, smiling.
“Sweet!” Peter said. “Speaking of the twins, are they going to Aunt Delia’s next summer like me and Kat?”
“Of course,” I said. “I’ll be super interested to see what kind of experience they have. Maybe it’ll be as good as yours.”
“Or better!” Peter said.
“Or better.”
