Robert had heard the noise, too, and seen his father's cock and balls pulsing as they repeatedly squirted jism into his mother's waiting mouth; what surprised him was when Carla climaxed, too, so soon after their father did. Disappointed when her clitoris suddenly disappeared back under its hood, Robert found consolation in the sudden supply of his sister's oils for him to lick up; it took a few passes of his tongue before he realized that what he was doing was making Carla's release not only stronger, but last longer, as well. The thought that he'd successfully pleased his sister after what she'd done for him left him feeling satisfied with himself… and finished the job of getting his cock fully erect again.
Ellen hadn't expected it when the penis in her mouth had suddenly begun spurting wads of hot semen, but she didn't mind. The suddenness of it even gave her the idea that it was Robert's cum, a result of his youthful inability to control his own pleasure. That thought was enough to send a powerful spasm coursing through Ellen's womanhood; while not enough to qualify as an orgasm, it was still strong enough to bring her considerable pleasure before she milked the last few drops of sperm from the manhood between her lips, and let it fall from her mouth.
After a few seconds, Ellen started to get to her feet again; seeing his mother move, Robert followed her example. It was nearly a minute before Carla had gotten her breath and senses back enough to make her way vertical again. All four family members looked decidedly uncomfortable as they faced the general direction of the three men that had violated the security of their home.
The silence seemed to drag out longer than it really took before the leader of the captors announced
"Well, now, that was quite a nice show you folks put on for us. Junior, it looked to me like you got the hang of eating pussy pretty quick; and the way missy acted, I gotta figure you must've done a pretty good job on her. And mom, I don't reckon your old man is gonna forget that blowjob for a good long time!"
Ellen, Robert, and Carla all three blushed before the man continued "I can see that junior's rarin' to go again, and I figure after giving dad head so good, mom wouldn't mind getting a little lovin' of her own.
So what I figure needs to happen is for junior to go on over and get mom nice and warmed up. And dad, you might as well find out what junior's been having fun with and have a little fun of your own with missy."
Neither Vic nor Robert moved right away; both had decided that they simply weren't going to go as far as their captors were demanding. But when the man with the pistol pulled the hammer back with a loud click and then told them "If you fellas don't get going real quick like, I'm gonna put a bullet in somebody's tit", they started to move-slowly and reluctantly, looking at their captors leader with hate and suppressed rage until each had gotten to his respective partner.
When he was standing in front of his mother, Robert softly told her "I… I'm sorry, Mom."
Just as quietly, Ellen answered "Never mind, honey. I know it isn't your idea."
Across from them, Victor told Carla much the same thing his son had said to his wife, and heard her answer "It's okay, Daddy. I know you won't hurt me."
A few seconds passed before a voice told them "C'mon folks, time to get things rollin'! Why don't you guys get things movin' by playing with some tits, huh?"
Slowly and reluctantly, Robert brought his hands up and placed them on his mother's breasts, just as he'd done to his sister; to his surprise (and quiet pleasure), he discovered that her mammaries felt nearly as good as Carla's. Larger and softer than his sibling's, they were still smooth and warm under his touch. Deciding that he could claim to be worried about upsetting the man with the gun, he didn't hesitate to begin exploring his mother's chest ornaments much as he'd done with his sister. As he did, the pleasure of having his hands overfilled with warm womanflesh began to make his dick feel even longer and harder than it had before.
Having her son's hands on her breasts made Ellen feel ashamed of what was happening, at first. But as he began moving his hands on them, gently squeezing and stroking their fullness, her embarrassment gradually gave way to a sense of pleasure with what he was doing. When his efforts expanded to include her nipples, the good feelings she was having grew even faster.
Vic had solemnly resolved that although he had to put his hands on his daughter's body, he was only going to go through the motions of actually doing anything: he'd make it look good, but he was determined that it wouldn't be anything that actually brought him any pleasure. That resolve lasted right up to the point that he first touched Carla by cupping his hands on her breasts. Unwittingly, he gave her small mounds a soft squeeze, and found out that they were as smooth and firm as he remembered girl's tits being when he was just learning such things. In addition, he could feel the hard pebbles of his daughter's nipples pressing into the palms of his hands; he found the stone wall of his resolve and commitment crumbling under the reality of his daughter's body in his hands. Slowly and reluctantly, he began moving his hands a little bit at a time, fascinated with the feel of Carla's young body.
The command that her daddy should start touching her and doing things with her didn't bother Carla in the slightest; in fact, she welcomed it. She loved him, and knew that he loved her, and she was grateful for the opportunity for the two of them to show each other that love. She was perfectly willing-eager, even-for him and her to take things as far as they could… even if that mean her daddy being the one to take her virginity. After seeing his erect penis, she knew that it wouldn't fit into her easily and that was okay with her; after what Robert had done to and with her, she wanted to feel her daddy's hard cock filling the emptiness she was feeling between her smooth thighs. As she stood there with her father's hands on her breasts, the idea of being fucked by him started to arouse her tremendously.
Ellen could feel that her nipples had gotten hard as a result of what her son was doing to her breasts with his hands, and she was long past feeling any shame or guilt about what they were doing. She was getting the kind of attention she hadn't experienced in months, and she simply didn't care who was doing it, or why; all she was certain of was that it felt good-good enough, in fact, that her clitoris was achingly erect and her pussy was wet and developing the empty sensation that all but demanded she find something hard to fill it. Remembering what she'd seen of her son's cock, she felt a mild thrill run through her body at the idea of having the building fires of her lust quenched by him, and started wondering: did she dare let it happen?
When Robert noticed an aroma much like the one he'd detected with Carla, he initially wondered where it was coming from; it wasn't the same, or even close to what his sister had smelled like… and besides, she was several feet away. Then it hit him: what he was smelling was his own mother's juices, and that was enough to tell him that she was getting excited-by him, and what he was doing! He'd been about to use his mouth on Carla when he'd learned what she smelled like, but he didn't dare suggest anything like that to his mother… then he started wondering: instead of using his mouth like he'd done with Carla, would it work if he used his hand, instead?
Without realizing it, Vic had gone from barely moving his hands on Carla's breasts to actively playing with them and her nipples, which had gotten longer and harder the more his hands moved on his daughter's chest. The longer he stood there with Carla's lovely body in front of him, the harder it was or him to resist the increasing temptation to begin doing all of the things that kept crowding into his mind: licking and sucking on the lovely mounds his hands were on, touching even more of her smooth skin on other parts of her body, finding out if her small ass was as tight and firm as it had looked, and so much more.
