The next morning, Phip wasn't sure how he felt. He had sucked his cousin's cock, and his father had sucked his, but he really loved fucking his mother and his sister, too. He walked into Julia's bedroom, wearing just his cutoffs She was still in bed, the covers pulled across her shoulder. When she rolled over to look at him sleepily, letting the blanket drop to her waist, Phip watched with delight as her breasts became clearly visible under her filmy top.
"What's up?" she said, checking his crotch to see if he had an early morning hard- on. She was a bit disappointed when he didn't, but felt she could change that with not too much effort.
"Can I talk to you?" he said.
"Sure, but give me a kiss first," she said lazily.
Phip sat on the side of his sister's bed and leaned over to kiss her. She reached up and put both her arms around his neck, pulling him deep within her mouth, darting her tongue inside him with wanton abandonment. "Are you going to fuck me this morning?" she asked dreamily.
"I want to talk about something first."
"Something sexy?"
"Well, yeah."
"I'm all a tremble," she said. "Shoot. I mean, go ahead, I mean, well, you know."
Phip started in on his story about fucking their mother and father, and how Dad was sort of the sex slave and had sucked his cock, and then about his adventure with Brad.
"Do you think I'm gay, sis?"
"Not any more than me," she said, and then started to relate her own experiences with Mom and Dad and Cindy. "I think it just means your sexual energy has been awakened and you're ready to explore it in any form it takes, including bisexuality. I think it's normal."
Phip liked the way his sister talked openly about anything sexual, and their parents were certainly uninhibited too. Maybe it was just his own personal hang-up. "By the way, where are Mom and Dad?" Phip asked.
"In their room, I think. Want to go peek in on them? Maybe they're in a horny mood."
"Have you watched them fucking before?" Phip asked, his erection starting in his pants as he remembered the hot session he'd been in with them.
"Watched and more." she said, grinning wickedly and running her tongue over her lips. "I fucked them both. God, it was great sucking Dad's cock while Mom finger-fucked me. And when Dad came in my mouth. Ummm. Talk about yummy."
Phip's hard-on had sprouted to full mast as he heard his sister's dirty talk. She reveled in the sexual act, and Phip knew he could learn some lessons from her. He looked at her heaving chest and watched lustfully as her tits rose with each breath. He reached to touch them, feeling the smooth flesh yield under his strong fingers. Julia came out of the daze of her lust-filled remembrances and reached over to massage her brother's cock.
"Oh, that got you hot, did it? Now you tell me. Have you fucked either of them?"
"Yeah, " Phip said, "I fucked them both, too, and at the same time. I think they must like threesomes."
"And maybe," Julia added with a grin, "foursomes. Since we've all fucked each other, why don't we go and look in and see if we can hop in bed with them. Come on." She hopped out of bed, leading Phip by the hand, her hand moist with anticipation, his shaking with desire.
They walked quietly down the hall. Just outside the bedroom door, Julia turned and pressed her tits against her brother's chest, inflaming him even more. She pulled his face down to kiss him deeply and draw him into her open lips, their tongues twining together, bringing the blood to Phip's temples. "Just to make sure you're primed," she said, and gently pushed open the door, stepping in with Phip's hand in hers.
Their parents were lying in bed cuddling. Mark's hand was playing with one of Josie's breasts and she was tweaking the nipple of the other one. "Well, hello kids," Josie said, not stopping her tit twiddling. "Come on over and kiss us good morning."
Julia led Phip over to the bed, then released his hand with a squeeze, patting him on the butt as he walked away from her toward his mother's side of the bed. Julia leaned over, exposing her tits to her father's appreciative stare, and kissed him on the lips, pushing her tongue lazily into his mouth, grasping his tongue as it oozed out to meet hers.
