We're going back in time with this story. It takes place while Melissa was pregnant with the twins. And both characters are consenting adults age 18+.
Some baby items they recently ordered from Amazon arrived that day and Jason went to the porch to grab them. Melissa offered to carry some of the bags and added that she knows how to grab a package. She kissed Jason and clutched his crotch as she said it.
Jason giggled and agreed. "You sure do, babe. And you're a great package handler who works hard." Melissa took Jason's hand and used it to stroke her growing belly. "This is a solid example of it. Of course, you played a part too." She smiled and winked at Jason. "Hey, I work in construction management. I know a thing or two about making stuff and using tools," he replied. They both laughed and Jason went to build some of the furniture.
While Jason worked on the furniture, Melissa did some light housework and started opening the packages with nursery stuff in them. Two packages had stuffed animals and plenty of onesies in them. Another one, as she happily discovered, held the music player she really hoped to get. As she opened the packages and started putting away items, the shirt she was wearing started feeling weird on her so she took it off. The tank top she now had on was staying on her fine...for now.
