Prickta did the same as the Futarian queen before and ran a finger on the crotch of her clothes, which also opened freeing her cock, but she continued to lift her finger until she met what looked like a pendant. In doing so, all the clothing on her body fell apart and was sucked into the item that the alien invader had hung around her neck. Her cock quickly became hard and she placed Mary on her cock, forcing her toy to stroke it to make her come.
Mary had never felt so humiliated and helpless before, but she had no choice but to obey the Futarian, and worst of all, even in the situation she found herself in, she herself had gotten hard.
"Do it more willingly Mary, this way you won't give me more than a half-assed orgasm." Prickta said, forcing Mary to pick up the pace. She did it thinking maybe that way she could buy time and help her "brother" escape.
After a few minutes Mary felt a strong pulse and the alien announced that she was going to come, soon in segyida reaching her orgasm and her pink cum gushed through the laundry room of the house.
As she came, the Prickta let her guard down and quickly doubled over, bringing her hands up to her ballsack. Mary only didn't go to the ground because she grabbed the alien's foreskin, who had her orgasm interrupted.
She quickly understood what had happened, as she saw Matthew running towards her, there was a slingshot positioned behind her and a marble on the ground. Mary's brother had waited for Prickta to be distracted by coming and fired a marble, which hit her ballsack hard, causing her a lot of pain.
"Mary come quickly, this is our chance to escape." Matthew said pushing a pile of clothes under her sister so that she would jump and have her fall cushioned.
"Damn it, I didn't think there were any other Earthmen in this house and let my guard down. I swear that when I catch you I will kill you." Prickta said, still bending over the testicular pain Mattew caused her.
The siblings took the opportunity and ran out of the laundry. "What are we going to do now Matthew? Hiding isn't going to work, she has a device that can detect where we are." Mary said
"I know, I saw when she found you. But I realized that after finding you she turned off the device without trying to see if there were any more of us here. This makes me think that the device cannot detect the number of humans, only if there is one and the proximity of the closest to it. So I came up with a plan for me to rescue using some old toys of mine that I still had in storage. I myself wasn't sure it was going to work." Mattew said
"I'm grateful that you rescued me from her, but it'll be useless if she catches us." Mary said
"I know that. I have an idea, but it's a bit extreme." Matthew said bending down right away.
Mary noticed that her 'brother' had guided her to the bathroom and was removing the toilet drain cover. She understood what the plan was and decided to go with it, believing it to be better than being captured again.
"Let's go, we don't have much time." Matthew said, and they could hear the beeps start again and then the sounds of someone running through the house, which indicated that the alien had recovered enough to catch them. She jumped down the drain and disappeared from view.
Mary approached the drain too, but before she could Prickta reached the bathroom door, where she said angrily "How dare you try to run away from me? You are my toy, a slave who must do whatever I say."
"That's your decision alone. We humans are capable of doing things you can't imagine, especially when our lives are at stake." Mary told Prickta and jumped down the drain, where she could hear a roar of fury as she slid down the pipes, which she followed until she reached the sewers where she rejoined Matthew. The place was dark, but after their eyes got used to it they could see enough to walk around, just being unable to differentiate the colors perfectly.
The siblings ran through the sewers looking for a safe exit, Mary a little calmer saw her 'brother' running naked next to her and her saddle breasts swaying, she realized that Matthew's breasts were at least a cup size bigger than the her. She felt her cock throb and get hard, thus slowing her running.
Mattew noticed the change in her sister's stride and turned to her asking what the problem was, and Mary responded by saying it was her dick, as she wasn't used to having one and the aliens having increased her libido were doing its effect.
"So we're going to have to work this out. If you can't run right because of this we run the risk of being found and recaptured more easily. I was also having this problem, even though I had a dick all my life, these breasts... especially the nipples (she blushed) are so sensitive and feel so good." Mattew said
Mary felt her cock throbbing again hearing her 'brother' talk about her own breasts. She realized deep down that she wanted those breasts somehow and Matthew noticed it.
"Are you wanting my breasts?" Mattew asked
"I'm sorry, I can't help but find them attractive." Mary said blushing "I'm very sorry. Please forget what I said, this is all wrong. Could you please give me some privacy?" she said turning her back to her 'brother'.
"You can...uh...do that." Matthew crowns as she said
"Do what?" Mary asked
"That thing...you know...playing with my breasts." Matthew said, blushing even more
"You're not serious, are you?" Mary asked
"I'm serious. It's weird for me too, I've been with some girls and I grabbed their breasts, but having someone do the same to me is weird." Mattew said
Mary approached her 'brother' and grabbed her breasts, who moaned at the touch and got her cock hard too. "Hmmm, Mattew, could you lie down?" she asked her 'brother'
Matthew lay down on the floor as herķ sister asked, who sat on her placing her cock between her breasts, then Mary pressed her tits together and started to fuck them. She thus loved her older sister about her and reached for her own cock, stroking it. Finding enough movement, she took he other hand up to Mary's ass, where she stuck a finger in her ass.
The siblings continued until Mary came and, jet after jet of her cum hitting her 'brother's' face, and shortly afterwards Matthew came too, with her shooting her cum into her sister's back.
When they finished cum, with their dicks going limp, Mary and Matthew continued to look for a way out, but it had started to get darker and they realized it was getting dark. They then chose a ladder they climbed up, which led to a drainage grate that they managed to pass at their current size.
When they came out of the sewers they came across....
