Gary Newandowski formed a close bond with his son Chuck a couple of years ago. They've kept the source of their bonding a secret from Sharon who is Gary's wife and Chuck's mother.
It started a few weeks before Chuck graduated from high school. He was a star on the basketball team and was dating one of the cheerleaders, a 5-foot-7, busty blue-eyed blonde named Stacy. During Chuck's senior season they both turned 18 in February. Gary knew they were happy and spent a lot of time together during the season and in the spring.
The week before Memorial Day, Gary had gotten home from work early and was heading to his room to get changed when he heard the unmistakable sounds of sex coming from Chuck's room. Gary cracked open the door to see what was going on and his jaw dropped when he saw Stacy riding Chuck reverse cowgirl.
Chuck was flat on his back on the bed, his view of the door blocked by Stacy. The sight of Stacy's swinging tits, which Gary guessed to be a 40C, her swinging hair, and soft moans were too much for Gary. He undid his pants, took his cock out and started to stroke.
At this moment, Stacy who had been riding with her head down, lifted her head and opened her eyes. She spotted the open door and Gary stroking himself. Instead of screaming in shock, she smiled and winked at him. She moved her right hand to her breast and raised it so she could lower her mouth and swirl her tongue over the nipple.
Gary was starting to stroke a little faster as she winked at him again and then laid back and whispered something in Chuck's ear. She climbed off Chuck, who had his eyes closed, and turned her back to the door. She bent over, taking Chuck's cock in her mouth while wiggling her ass at Gary.
This got to be too much for Gary who quietly closed the door and quickly ran to the bathroom and stroked himself to a powerful orgasm. He then went to his room, got changed, and went to out to do some yardwork.
That night Chuck went to Gary's basement office.
"Dad, can I talk to you about something?" Chuck said.
"Sure, what's on your mind?"
"it's a little embarrassing and I definitely don't want to talk about it in front of mom."
"What is it?" Gary asked, turning his full attention to his son.
"As you've probably guessed Stacy and I are having sex."
"Yes, she's a very attractive girl and I hope you're using protection."
"We're using protection. But to get to my point, we've been watching porn together and this afternoon she expressed an interest in wanting to have a threesome with another guy."
"How do you feel about it?"
"It might be kinda hot, but also a little weird."
"How so?"
"It would be hot to watch her blow another guy while I fuck her, but weird if it as a classmate who might talk about it in school or a complete stranger."
"That eliminates a lot of possibilities. Have you two talked about who the third would be?"
"We did and I'm a little weirded out by her suggestion, which is what I wanted to talk to you about."
"Go on."
"She said since we don't want it to be a classmate who might say something, no matter how much we trust him and we don't want it to be a stranger, it has to be someone else we know. She suggested you."
"Me?"
"Yeah," Chuck said. "I told her I needed to think about it and talk to you. It would be weird watching you cheat on mom with Stacy and weirder sharing her with you. But on the other hand, I want to grant her wish and we know you'll never say a word about it. What do you think?"
"Son, in the 20-plus years I've been married to your mom I've never cheated on her. I was tempted once and while watching and reading porn have often fantasized about fucking other women, but have never gone through with it in real life. However, I'll do it for you, knowing you and Stacy won't say a word about it. Your mom is on a business trip next week. Bring Stacy over on Tuesday and start doing what you two do. I'll come home from work early, sneak in to the room and join in."
"Thanks dad."
"Thank you, son."
That Tuesday, Gary came home from work to find Chuck and Stacy were naked. Chuck was lying in his bed and Stacy was bent at the waist with her lips wrapped Chuck's thin 9-inch cock bobbing up and down. Gary, after watching for a few minutes, snuck in and knelt behind Stacy and started to lick her pussy.
Stacy gasped in shock before resuming her licking and sucking of Chuck's cock. Gary moved his head between Stacy's body and the bed and began to flick and lick his tongue up and down the length of Stacy's moist folds from the front before sliding his tongue between them. He moved a hand up and started to gently began rubbing her clit while continuing to tongue her pussy.
"Oh god!" she moaned. "That feels so fucking good."
Gary continued to lick her, sucking her moist lips into his mouth, savoring her juices.
Stacy, who had now taken her mouth off Chuck's cock and was only stroking it, was moaning louder and babbling incoherently how good it felt.
Not letting up, Gary started to finger fuck her slowly while licking her clit.
"Holy fuck I'm cumming!" Stacy half-shouted, half moaned, as she moved her hands to hold Gary's head in place as her whole body shook in orgasm.
"I need some cock in me now," she said. "Chuck get behind me and pound me while I blow your dad."
Chuck quickly grabbed a condom off the nightstand and got behind her while Gary jumped up and stood in front of her, his thick 7-inch cock sticking straight out.
Stacy smiled when she saw Gary's cock.
"Your son is a few inches longer than you, but you're thicker, I think I'll like that," she said before starting to lick up and down the length of Gary's cock.
Chuck, who had put the condom on, stood behind her mesmerized at the sight of her licking his dad's cock. He began teasing her by rubbing his cock up and down her pussy.
She paused her licking to look over her shoulder and smile at Chuck.
"What are you waiting for? Fuck me!" she demanded before lowering her mouth over Gary's cock.
With that Chuck grabbed her hips and slammed into her. He started fucking her hard and fast. Each thrust forced her head further onto Gary's cock. Gary grabbed her head and helped guide her for a few minutes before easing it off him so she could lick the length. She then proceeded to suck his balls one at a time while stroking his cock.
Chuck leaned forwarded and was squeezing her tits as he thrust.
"God I needed that," she moaned and started to buck her hips back at Chuck.
Chuck continued to thrust into her as she continued her oral assault on Gary's cock.
A few minutes later Chuck started to groan, "I love how tight you are and I'm almost there."
"So am I baby, please cum with me," she panted as she started to urgently stroke Gary's cock.
Moments later it happened.
"Uuuugggghhh," Chuck groaned as he held himself inside her as he came.
"Oooooohyyyeahhh," she moaned as her body shook while not letting go of Gary's cock.
"That was great," she smiled.
"You're not done yet," Gary said as he grabbed a condom from the nightstand and put it on before sitting down in Chuck's desk chair. "I haven't cum yet and you're going to ride me until I do."
