Not in there for long

You wiggle about as the sperm squirm around you. You hear moans of pleasure from your mother and feel rhythmical up and down movement from above. That movement is quickly joined by a similar motion from below. Within a few minutes, at your best guess, You are squeezed hard and begin moving upwards at a rapid pace.

"OH YES!" Your mother shouts as she cums.

You shoot out the tip of her cock and squirt all over her belly, coming to land on her belly button. Both of you took a moment to recover until you saw your mother's now even larger form staring down at you.

"Oh, my child, that felt so good, I just couldn't resist pleasuring myself, what an interesting result. On top of that, it seems you have shrunk even more. I did want to see what happened if I kept you in there for longer. I think we both need a chance to clean up before we write up the results of this experiment and I will see if I can restore at least some of your height." Your mother said, still a bit breathless after an intense orgasm. She scooped you out of her belly button and let you sit in her open palm as she got up and moved to the bathroom. Looking down you saw cum splattered all over your mother's belly, her cock was limp, semi-hard, sticky with cum and dangling between her legs, swaying as she walked. There was a wet patch on the bed where she had been sitting as she had squirted femcum from her intense orgasm.

She put the plug into the sink and ran the hot water just long enough to create a small pool, that was like a bath for you at your current size. You washed off and listen to your mum take a shower. When she had finished and drys off, she takes you down to the lab. First, she gave you a drop from a vial labelled XD101. You felt you felt a tingling sensation and you felt like you were moving upwards. Your feet however remained on the ground. After a quick measurement, it seemed you had grown back to being 12cm high. You wanted to take more but your mother said that it was dangerous to take too much and grow to fast. This seemed odd as how would she know if she hadn't tested it yet?

After this, you felt very hungry. You suspected it was due to the sudden change in height. Your mother took you to the kitchen and made lunch. She made a ham and cheese panini and used an apple corer to take a section out of the middle and gave it to you. You ate it ravenously as your mother also ate her lunch fast, she was hungry too.

"I think you have had enough testing for today. " Your mother remarked. You watched T.V for the rest of the day. Before bed, your mother took a small DNA cheek swab and tucked you into your massive bed. Here, drink this it will help you sleep. She hands you a tiny bottle. Without thinking, as if you had done this a thousand times, you take a sip from the bottle and everything goes black.
