The bed was shaking slightly, and Barbara opened her eyes. Dawn was breaking, and the early morning light revealed Richard and Abigail, eager for more loving. Abigail was crouched between Richard's legs, her mouth molded tightly around his cock, pursed lips sliding up and down the hard, stiff shaft. Abigail released his cock from her warm, wet mouth, and Barbara watched as she saw Abigail opening a condom package.
Abby giggled as she said, "So nice and so hard, so ready to fuck me again. Let me put this on for you, my sweet brother. I want to put what I learned in our sex-ed classes to good use. It felt so good, having your warm load of incestuous baby-making sperm spilling into me last night. Although the idea of being bred by my brother sounds exciting, in real life, well, big problems!"
"Oh yeah, Abby, wrap me up, baby! It was great that Auntie Babs was prepared, and let me go off inside you that first time!" Richard growled huskily.
Abby purred, "Ummm, oh yes, I loved to feel the tremors of excitement through your cock when you were deep inside of me, then the feel of your passionate eruption, flooding me with your wet spray of sperm, that wonderful rich, liquid warmth jetting into me, filling me up. My whole body was tingling with the hot, sexy sensations shooting through me. I love it, and I love you. It won't be long before you can again ride me bareback, oh yes, I'm eager for that, but for now, we need your hot, sexy cock wrapped up!"
Barbara was on her side, facing them about 3 feet away. She wanted to watch them without jumping in, and she kept her eyes open slightly, feeling the tingles of her quickly waking lust deep down, as she watched Abigail placing the condom, then unrolling it down that hard, stiff 8 inches, until Richard's cock was sheathed in the latex.
"Oh yeah, you're all wrapped up, just like a present. A present for me, come, Richard, give me that present, bury that beautiful cock deep inside your sister's pussy!"
Barbara watched, her juices starting to churn, as Abigail lay back, smiling up at her brother, nudging his cock against her, ready to give Abigail what she wanted.
"All one thrust," Abby growled, "Bury your cock in one thrust!"
Richard was eager to do so, and he drove his hips forward. His cock surged in, and Abby let out a squeal of pleasure as she was parted, her tight, pink sugar walls being split apart. Richard grunted as he was engulfed, even though there was a condom between them, the sensation of being buried deep inside the clutch of his sister's tight, almost virgin fuck hole was out of this world. He felt Abby's legs wrap around his waist, opening herself up as wide as possible, wanting every last bit of his cock deep.
"Now, fuck me, Richard, fuck your sister, just before you cum, pull out, let me yank the condom off you, then shoot your thick load all over me! Christen my body with your load of hot, incestuous cum!"
He felt his lust pump up, oh god, he'd wanted to shoot his load all over a girl's body, and here was his sister, no less, urging him on. That made his cum start sizzling, he knew he was close. Listening to the cries and grunts of his sister getting power fucked just added to the heat, and he felt poised. Just as his cock was ready to blow, he growled, "Oh yeah baby, gonna blow!"
