Well, as much as we tried Janine did not become pregnant that first month. This didn't dissuade us from trying a lot though!
After talking it over with Bobby and Janine, we decided to invite their cousins over to join in our fun. Bobby had lusted after Tiffany's huge tits for years and Janine said she found Chris attractive.
Everyone got together on a Friday night after all of their classes were over. I hadn't been with Chris or Tiffany in some time and the thought of fucking them again, and watching them fuck each other, had me very turned on.
Janine had also agreed to try making love with Tiffany, a first for her. She also wanted me to take care of her last first by screwing her in the ass for the first time.
Tiffany and Chris were still gorgeous. College football had made Chris even more buffed. Tiffany was also doing well in school, really getting her life together. They both gave me a big hug and kiss when they came in.
Everybody knew what we were there for and, before long the clothes started to come off. Tiffany was wearing a beautiful blue lace bra and matching panties. Janine, not to be outdone by her older cousin, wore peach-colored underwear. We guys just had on boxers, though mine and Bobby's were silk.
The boys sat down on one couch and the girls joined me. Bobby and Chris hugged, then shared a kiss, their hands all over each other's muscular bodies. The girls and I just watched for a minute as they started making love to each other. Before long they were fishing each other's cocks out of their underwear. Bobby took the lead and leaned down to take his cousin in his mouth.
On our couch I kissed Tiffany, then Janine. I cupped my niece's breasts in hand, glorying in their firmness and size. Janine was busy rubbing my back.
I scooted up and pulled off my boxers, revealing my hard cock. The girls needed no more invitation and went down on their knees and started to blow me. Their hands and tongues went from my asshole to my balls and all the way up my shaft. The two girls shared a kiss with my cock between their lips.
I knew Janine had never been with another girl and Tiffany very infrequently, so I decided to ease them into it. I had them remove the last of their clothes, sat up, and guided Tiffany down onto my cock. Janine sat back and watched her cousin ride me, then I motioned her over. I pointed to Tiffany's bouncing tits. My daughter tentatively took one in her hand and rubbed it. Tiffany smiled at her as she continued her ride.
Emboldened, Janine took Tiffany's erect nipple in her mouth. Her hand went down to rub my balls and Tiffany's blonde-muffed slit.
"Oh, yeah Janine! Rub us!" Within minutes Janine and I brought Tiffany to a screaming orgasm.
I look over at the boys who were now in a 69, wolfing down each other's hard young cocks. It didn't take long for them to fill each other's mouths with cream.
"I'm gonna cum, Tiff. You ready?"
"Oh yeah, Uncle Joe! Fill me up!" With that, I shot rope after rope of hot semen into my niece's waiting cunt. She got up and looked at Janine. "Cousin, why don't you eat your father's sperm out of me?"
"Okay!" My daughter dove for her cousin's pussy, lapping at it like an old pro. I sucked on one of her tits as I watched. The boys, not wanting to be left out, came over. Chris was hard again and, after slipping on a condom, shoved his cock in Janine. Bobby came over and cleaned off my cock with his mouth.
