And so, You and Mandy ended their session, and began to watch TV after washing up.
You felt odd. You felt a higher sense of things around you, and felt more focused...and yet the same.
"What do you wanna watch?" Mandy asked, looking through some of your DVDs.
"Whatever you want, it doesn't matter." You answered. Really, it did matter, but you were preoccupied. Your focus on the world around you began to narrow. It was like you were coming down from being on a drug that heightened your senses, and the focus was slowing centering itself around Mandy.
Mandy flipped through some of the DVDs and picked one out, and showed it to you, and you nodded, not even seeing what it was. The focus finally leveled off, and you felt a connection form between you and Mandy's body. It was like you could tell everything about her, with mathematical precision. It was like it came naturally. Her height, bra size, weight, every measurement of every angle and length throughout her body, you now knew, and you didn't even have to think much to know.
Mandy bent down to put the DVD in the player, and you discovered you could change those measurements. You didn't know why, nor did you know why you knew, but you just knew.
Mandy was bent over, on her feet, in almost a fetal position, giving you view of her back. She stood up, and turned around, and you made Mandy's breasts grow slightly.
Mandy looked down at her chest, which slowly swelled up, and bulged in her bra. She gave a confused look, and adjusted her bra slightly, only to get no comfort.
You smiled, and suddenly knew the connection. Your semen gave you control over her body size for some reason...
