Abigail smiled, she had seen how flushed her Auntie Babs had looked when she came downstairs, and Abby wondered if her Auntie had been in the shower with Richard, washing his back, and probably doing a lot more. Abby had discovered that she had a voyeuristic streak a mile wide. Watching her auntie masturbating, and watching Richard have his way with her at the kitchen sink yesterday, had ignited that need, and she wanted to see a lot more.
When Abby said her goodnights and went to her room, she stayed wide awake, hoping for more action that she could spy on. As it was, she didn't have to wait very long.
About 30 minutes after Richard and her Auntie Babs went to bed, she could hear his stealthy footsteps passing by her door. She eased her door open and saw him creeping down the hallway to her room. When he eased open the door, then closed it, she dashed to the bathroom connected to the master bedroom, slid in quietly, and inched forward. She saw it, and watched, and drank her fill.
Richard had turned on the overhead light to a dim glow, perfect, Abigail could see what was about to happen. She saw her brother drop his robe, his cock hard, eager, and ready. Abby stifled a growl, god, it looked so sexy, so hot, that 8 inches of pussy filling pleasure eager for Auntie Babs. Richard slid into bed, and his hands slid back the bedcovers, and his hands stroked and caressed her body, eliciting soft moans and sighs, until Auntie Babs awoke. She rolled over, facing him.
Her voice, husky with desire, cooed, "Oh yes, so glad you came back, I don't give a damn if you are my sister's son. Just fuck me, fuck me, your cock is too hard, too stiff, too perfect, to say no, I want your pussy pleaser deep inside me!"
His voice growled back, "Oh yeah, I love fucking my Auntie Babs!"
Abby could feel her pussy heating up quickly, hearing them say such things was wildly exciting. She watched her Auntie relaxing on her back, and Richard climbing between her thighs. He paused, then he thrust his hips forward, Auntie Babs let out a squeal of pleasure, and Richard replied with a grunt as he buried himself. Pulling back, he quickly entered into a rhythm, driving his cock forward and back, in and out.
"Yes, oh yes my darling nephew, give it to me, let me have it!"
Abby could see that Richard was happy to oblige, riding deep inside Auntie Babs, she wondered if her Auntie's pussy was as hot as hers was. She could feel the juices dripping, running down her thighs. She reached up, pulled a towel off the towel rack, and stuffed it between her legs. The towel slid over her aroused clit, oh that felt so good. She grabbed the ends of the towel and started to saw it back and forth between her legs, feeling her clit tingling as the towel's plushy fabric swiped against it over and over.
Richard was fucking Auntie Babs faster, the bedroom was full of their mingled cries and grunts of pleasure. Abby was glad because she couldn't help it, she was making noises of her own, her clit was throbbing, and she could feel it building. Through lust-glazed eyes, Abby watched as Richard stiffened up.
"Oh yeah, cum with me, cum all over my cock!" Richard growled.
"Yes, yes sweet nephew, give me everything, fill me up with that juicy wet spray, yes, oh yes, YES!"
He thrust hard, and let out a roar, while Auntie Babs' cries of sexual completion filled the room, and Abby joined them, her pussy pulsing with the force as her orgasm rushed at her, doing her best to not cry out too loud, lest she be discovered spying.
Abigail slumped down, gasping for breath, jeez, her orgasms were like a thunderstorm when she was able to watch. She observed more, as Richard pulled out and re-positioned himself.
"Now, I'm going to lick the sweet pussy I just fucked, I want you to cum by my tongue, Auntie Babs!" Richard growled.
Auntie Babs cooed, "Do it, my sweet nephew, get your cock nice and hard again, and then I'm going to suck every drop out of that hard, stiff beauty!"
Abby watched, the tingling starting up again, as Richard pushed his face eagerly into the spread V of Auntie's thighs. She heard Auntie Babs squeal of joy, and the moans of passion as Richard settled into licking at her, licking at the pink seam. Abby was eager to know what that felt like, she'd never had a tongue down there, let alone a cock. Judging from the sounds of passion Auntie Babs was making, it sounded like it must be really good.
Suddenly Barbara cried out, "Oh my god, making me cum, yes, yes, cumming, YES!"
