Mark!

Your body convulses with a screaming, earth-shattering orgasm as you see your middle son fee out of the ladies bathroom. It takes more than a minute before you can speak and start to warn Pam as she covers you with kisses all over your face and tits. "Pam... Pam... PAM! Stop!".

"What happens, my love?" she says, her lips on your hard nipple, the vibrations of her voice transmiting through your flesh, amking you shiver.

"It's Mark. He was here, in the bathrom. He saw us. Or at least he knows."

"Dammit. I'll talk to him. Let leave." She says as she starts to fix her clothes.

Once again back, Pam grabs Mark for a one on one conversation as she deflects you towars your other children."Everything OK? You seem flushed, Miss Fiona." Sara says.

"I'm fine, today was... hot. And the bathroom wasn't particularly well ventilated." You say, as you catch on Pam and Mark's conversation: something about her feeling alone, you being supportive and kind, etc.

"Yeah, I feel I could faint if it wasn't for the Powerade." Austin says.

"That makes sense, I guess." Sara says.

"So, I missed excersing. First time since... well... It was a good run, it felt good to excersice, don't you think?" You look at Mark from the corner of your eye. He doesn't look particularly angry or disappointed that you and his mother had sex, he is simply blushing and... Is he trying to cover an erection?

Austin and Sara sadden for a second when reminded about the hospital, hence their assumed father's ****, but are soon trying to look happy, answering positively to your question. However, half of your attention is on Mark, and your mind wanders for a slit second, imagining your son's erection in full display and how big he might be, then at last night masturbation session, touching yourself, enjoying the feeling of your new feminine bits, fantasizing about getting fucked by a man. You get wet and you want to believe it was thinking about sex and not you son's cock what got you this excited.

Some time later you all go back and soon are back at your front yard, where you say your goodbyes to your family. They bid you farewell too, Mark being shier than his siblings, before waking another few meters to reach your former home. You go inside and try to be occupied to avoid thinking about being separated form you family again. You cook yourself, and then eat, some lunch before having a shower and then going back to your book.
