Alesha said, "Well, there are two places you can ride.
"The first is up here," as she raised you toward her cleavage, "but I jiggle a lot, and I'm a little worried that you'll get hurt, or sick. Or..."
Steve caught on suddenly, and just as suddenly lost two-thirds of his already-insignificant height, winding up only an inch tall.
Alesha's eyebrows went up as Steve dwindled in her hand, and said, "Well, I guess we know what option works best for you!" She ducked inside the still-open door of your house, and into the bathroom just off the foyer, closing the door. She placed Steve gently on the counter, unbuttoned her jeans and, pulling both them and her panties down below her knees, sat down on the floor.
Alesha then reached back up and gently picked up Steve from the counter, and brought him up to her face. "You should be just fine inside me," she said, "but try to stay as far in as you can; I don't want you to fall out and get lost." Having said that, she laid back and, bringing up her knees and spreading her legs, pushed Steve up into her vagina as far as she could.
Alesha then pulled her panties back into position and, standing up, pulled up and rebuttoned her jeans. I don't freaking believe it, she thought, I've actually got Steve up inside me, nobody but he and I knows, and I can keep him inside me as long as I want. The feeling of power this thought gave her was, she realized, a little dangerous, but she decided to enjoy it until they got to school.
At least.
