Jonathan hands Mary the female vial, "Drink it all."
Mary drinks as ordered and hands back the vial, "What will that do?"
Jonathan looks into her eyes and murrs, "Many lizardsss and reptilesss..." He starts out calmly, "They must have eggsss inssside them in order to be fertilized, much like mammalsss..." He chuckles some, "I could sssmell you were nowhere near ready, no eggsss at all developed inssside of you. Theoretically... Drinking that being already female should push you to that period of time where you are mossst ready for a mate."
Mary's breasts begin to swell as the female vial takes effect on her already female body, and indeed her belly began to press out developing eggs. She moans loudly and falls to her knees beside her bed as her body is forced into this part of her cycle. Jonathan watches, pleased to see his mate on the ground before him. "Get on the bed, it'll be a lot more comfortable." She climbs onto the bed as waves of pleasure begin to hit her from the awkward stimulus, causing her to moan louder, her once large B-cup sized rack now hitting a large DD.
"What have you done to meeeee?!" Mary asks loudly in the moment. Her body soon starts to slow in the adjustments, and along with it the pleasurable feelings cease. She sits up feeling normal with a rather heavy looking belly. "I'm pregnant?!"
Jonathan chuckles, "No, not really pregnant ssso much asss swollen with eggsss. But you will be laying in about a day now by the looksss of thingsss, ssso I'd best fertilize thossse eggsss before then..." He removes what's left of his pants, revealing a slit from which his erect lizard-like shaft is poking out. He looks at her lustfully hiding the male vial from her view.
