He takes two

Richard popped two pills into his mouth and dry-swallowed them. It took a few moments for him to feel a buzz going through his body and it especially concentrated around his cock and balls, both of which felt like they were surging with extra blood flowing into both. He quickly took off his pants and looked as the shaft turned a slight reddish color before it blended back to his skin tone. It did appear longer, though, and he noticed that his testicles had grown in size as well. Otherwise, at first, he didn't feel that much different.

Sliding his pants back on, he walked downstairs and looked around, finding his mom in the kitchen. "Hey mom, where's dad?"

She looked behind her and shrugged. "He went out to go fishing, said he'd be back in a few hours."

"Hey kiddo!"

Richard turned and looked at the other person in the kitchen. "Oh, hey, Aunt Viv."

Richard wondered just how effective this would be and, with a little decision, he slipped out two pink pills and dropped them into Vivian's cup while she wasn't looking. The two of them continued to talk and he just hung back, watching them as she drank the rest of the lemonade. "Woah...guess I'm a bit more tired than I thought."

Mom looked at her sister for a moment. "Well, it's getting a bit late. Richard, why don't you help your aunt to the guest room? I'm going to go shopping for some groceries, if your father brings back what he claims will be dinner, we'll need some things to go along with it."

He nodded as his mom walked out of the house and as she drove away, he turned and helped the other woman to her feet. She was softly moaning but as Richard placed his hands on her, she stiffened and then relaxed as he helped her move towards the guest room. He could definitely feel her body next to his, the pressing of her breast against his arm or the way she smelled.

Vivian, for her part, found herself sweating and the feeling of her nephew next to her was driving her crazy. She had only known him for the past 3 weeks, knowing that he was an XChange user, and that they were biologically related but that was most of it. Still, in the past 3 weeks, she could see how he was a good fit for the family, how he had been a good son for them, and she was happy to see her sister happy. Still, she recognized the differences in them, he was a young man, she was a middle-aged woman, her breasts were aching to be touched, to be fondled and caressed. Lower, she could feel her pussy becoming wet and her clit was aching, aching, to be touched as well. She leaned in next to him as they turned the corner and she took a deep smell, his scent was overwhelming and she only held onto her sanity and propriety by the slimmest of margins. If he were to take her, overpower her, make her do things...
