Ryan, Penny, and Suzy had plenty of room in the big walk-in shower of the master bedroom to soap each others bodies and slide their hands over every square inch of one another's glistening skin.
At one point, when Penny was sliding one hand up and down Suzy's butt crack, and massaging a slippery tit with the other, she wiggled a finger tip around her tiny ass hole, and said, "Have you guys ever done anal?"
"We tried, once," Suzy said, "but it hurt too much." She through for a second, and added, "But I really liked it when you fingered my butt while I was cumming."
"You mean like this?" Penny said, as she gently pushed her soapy middle finger up Suzy's ass.
"Mmm!" Suzy replied, as she wiggled her butt, and pushed back against the finger.
With wet slapping sounds, Penny began to finger-fuck her little ass hole, and Suzy leaned over, put her hands against the wall, and spread her legs.
Ryan took over the job of massaging and squeezing her tits, and Penny knelt down to where she could watch her finger slipping in and out of the tiny pink pucker.
After a little while, Penny added a second finger, which Suzy made no complaint about.
When she added a third, she had to push a good deal harder, and she asked, "Are you still okay?"
"Yeah," Suzy said. "I feel stretched, and it hurts a
little
, but it feels good at the same time, you know? Don't stop, but no more fingers, okay?"
As Penny finger-fucked her ass, Suzy reached down, and began to finger her own pussy. She quickly had two fingers ramming into her cunt as Penny's three stretched her ass hole. The combination didn't take long to push her over the orgasm edge.
When she caught her breath, she said to Ryan, "Maybe we need to give that another try." She turned and kissed Penny, and added, "With a good coach."
"You up for it, little brother?" Penny asked.
"Heck, yeah!" he said, sliding his hand up and down his hard soapy cock.
"I mean
getting
, not
giving
," Penny said.
"What?" he said.
"Turn around and put your hands on the wall," Penny told him.
"I don't know about this!" he protested.
"You just watched Suzy take three fingers, and enjoy it," Penny said. "You think her butt hole is bigger than yours?" She pushed him on the shoulder, and commanded, "Assume the position!"
Suzy laughed, and said, "Just trust the coach; she knows what she's doing."
"Okay," Ryan said as he turned, reached out for the wall, and spread his feet. "But only
one
finger!"
Penny soaped up both of her hands, and as she slid one of them up and down his butt crack, she wrapped the other around his stiff cock, and began stroking it.
Keeping her wrist tight into his now-slippery crack, she reached between his legs, and began to massage his balls. As she jerked him off, she mashed her cock-hand down into her handful of wet, soapy balls with each down-stoke.
She then slid her hand back up his ass, and while still stroking his cock, she began to wiggle the tip of her middle finger against his tight sphincter.
Well past the point of saying stop, he relaxed as much as he could, and found that he actually enjoyed the stimulation.
Slowly, and with lots of soap for lube, she pushed her fingertip into his ass, up to the first knuckle. She then took it in and out several times.
He found that he actually liked the feeling of the penetration. He wiggled his butt, and said, "Go ahead and push it in deeper. That actually feels kind of good."
By this time, Suzy had gotten down in a crouch so she could see Penny's finger slipping into her boyfriend's ass.
Slowly, Penny pushed her finger deeper and deeper up Ryan's ass hole, past the second knuckle, and them as deep as it would go, with her hand pushed tight into the cheeks of his ass.
She then drew it all the way out, and slid it all the way back in, all the while jerking off his rigid cock.
"Go ahead and
fuck
me with it!" Ryan told his sister.
Penny happily complied, and began shoving her finger faster and harder up his ass, and coordinated her strokes on his cock with her fucking. Each time she drove the finger deep in to his anus, her hand slid all the way down his cock to his balls.
"Oh, Wow!" was all he could say at the coordinated attack, as he leaned heavily against the wall with his head hanging down between his arms.
"Tell me when you're getting ready to cum," Penny said as she fucked his ass and jerked him off. She had one more trick—that she'd only read about in a porn story—that she wanted to try.
While Penny continued bringing him to the edge, Suzy worked her way around his spread legs until she was crouching in front of him.
With his soap-covered cock inches from her face, she said to Penny, "Jerk him off in my face! I've always wanted to see what that feels like!"
Ryan looked down at her face, right in front of his cock, and at his sister's hand sliding up and down its length, and said with a chuckle, "All you ever had to do was ask; I'd have been
happy
to oblige."
"I was afraid you'd think it was too weird," she said, smiling up at him.
He laughed, and said, "With my step-sister finger-fucking my ass and jerking me off, I don't think
anything
could be too weird, anymore!"
At the same time that Penny could feel Ryan's body start to tense up, he said, "Okay, I'm getting ready. Just keep it up, just like that."
He looked down at Suzy, and said, "You want it in your mouth?"
"No," she said. "All over my face! I want to feel your hot cum on my nose, my cheeks, even in my eyes! Squirt your fucking cock right in my face!"
The dirty-talk spurred both Penny and Ryan, and in a few seconds, Penny's finger pounding up his ass, and her hand flying up and down his cock had Ryan saying, "Oh yeah! Here it comes! Here we go!"
At that, Penny jammed her finger deeply into Ryan's ass, held it there, and began to rub her finger tip around on his prostate.
"
Oh, Jesus!
" Ryan blurted at the new and intense sensation that was like an electric shock right up his cock.
"You okay?" Penny said, not really sure if she was doing it right.
"
Shit, yeah!
" he said. "Keep doing that!"
He looked down at Suzy, just inches in front of his cock head, and said through gritted teeth, "That pretty face is going to look so fucking hot covered with my cum!"
"Oh, yeah! Do it! Cum all over me!" she said, with her eyes squinted against a possible direct hit in them.
"
Ahhhhh!
