Ty thought of a wish that felt like it'd be fun- she imagined shifting her perspective so she became one of her and June's babies growing inside her. That way she wouldn't have to deal with the awkwardness of living as a pregnant woman or birthing her children.
Her eyes seemed to roll back in her head as she moved inside herself, and found the body she was now inhabiting to be an egg nestled into her womb. She comprised two cells, the ovum which Ty had produced and the sperm of June's which had claimed it.
Rapidly, she began to divide and grow, steadily turning into an embryo and then a fetus. She saw the masses of fertilized eggs around her developing similarly, until she saw the scores of babies June had pumped into her had formed in the distended space of Ty's womb.
To her surprise, she saw something weird about this developing litter. They were sexually maturing, the males forming fully-developed penises and the females sprouting breasts and distinct vaginas. This, she realized, was a side effect of the virus- sexual assignment making people's libido stronger applied to gestating offspring.
Soon the foetuses resembled tiny adult men and women, and began to move towards each other and make moves on one another. Ty's heart pumped in this body's tiny chest as she saw males putting their cocks inside females and fucking them.
