(masculine) Morning surprise

Kelly and Jack both felt exhausted and for a while, they just cuddle on the floor.. "I... I better leave" Jack eventually says and gets up. Kelly is having none of that "Noooo..." She grabs onto her boy. "Stay with mommy... Please." Jack can't deny her or her puppy dog gaze she is giving him and they tuck in Kelly's bed. For Kelly, this is ...if not a return to normal (far from it as their situation is) at least a clear improvement. She loves her son and they had been growing distant but now she feels a closeness she has never had with him before as they cuddle under the sheets and fall asleep.

The next morning, Kelly wakes up refreshed. She stretches in the bed, feeling better than ever. The pain is gone and she believes frequent sex or masturbation is the way to ensure such pressure build up doesn't cause any issues in the future either. Thinking about it makes her aware that her cock is also up and awake. Kelly slides a hand under her sheets and slowly rubs her cock. This must be the "morning wood" that she has heard of before. Thinking about it, Jack is a grown man and perhaps he has similar issues... Last night was probably just a one time thing, Kelly doesn't even know if Jack would want to make love to his mother. But the thought is now in her head and it excites her. She felt a connection with her son unlike anything before and she wants more. Her hand is still sliding up and down on her cock as she reminisces the feeling of her son jerking her off and then deepthroating her massive cock. She wants more. She loses her train of thought when she looks over at her son and sees the way the sheets are bulging over him. "What on Earth?!" Kelly's exclamation wakes up Jack who sits up immediately and looks around nervously. "What's wrong mom?!" Kelly points down wordlessly. "What? ...Oh."

Jack pulls off the sheet and reveals that his dick is also foot long now. More than that, his body is considerably more athletic than it had been the night before. Kelly can't resist running her hand over his stomach and feel those rock hard abs. ...And that rock hard cock. "My... cream... must have caused this." Jack gasps as his mother wraps her fingers around his long and thick cock. Kelly bites her lip thinking. Jack's penis had felt good inside her mouth before, but they hadn't gone all the way, and with this monster between his legs now... Kelly feels her vagina and it is wet with anticipation. "Son... We need to... inspect the changes in your body... Just to make sure that everything works..."
