It's Been Contaminated

You loved to admit it, your mom was a sexy hot milf, who you'd loved to fuck up. After making you both strip completely naked she continued about her usual routine, but you had trouble taking your eyes off her. That is sexy fat ass. It was enormous! And yet the rest of her body was so slender... You tried desperately not to let on that you were fascinated. The way she walked around the apartment, buck naked without a care in the world - she kept turning you on. You tried focusing on video games instead. You loaded up Final Fantasy and let yourself get sucked in. After a while your mother's bare bosoms came bouncing into view.

"Whatcha playing, sweetie?"

"It's, uh..." Look at her face, not her boobs. "It's a role-playing game."

"Ooh, I know what role-playing is! I did theatre back in college, you know." She watched the screen as you finished off another group of attacking monsters. One of your heroines cheered and struck a pose in an outfit that was typically scanty for a Japanese game.

"I can do that, John. Look!" She put one hand on her hip, stuck out her tongue, made a V-sign with her other hand, and jiggled up and down, before look down at my crotch.

"Whoo, yeah! ... Oh my god, is that what I think it is?!" She was pointing at your crotch. Your dick was very clearly erect and pointed straight at her.

"Mom! It's not what you think! I'm sorry..."

She shook her head. "Don't be, baby. It's not your fault. It's the virus."

"What?"

She sat down on the couch next to you. "One of the symptoms they were talking about on Instagram was sudden inexplicable erections. Your penis has somehow been exposed to the virus. We need to clean it before it invades the rest of your body."

You told her that didn't make sense but she got up and grabbed a bottle of hand sanitiser. She pumped it into her hands. It didn't look like normal sanitiser either. It was thick, and slimy.

"This is a special ****-free, all natural hand sanitising moisturiser. I got it from a website, it was very expensive so you know it's the best."

You were going to object but then her slicked up hands touched your dick. It was heaven. Whatever this stuff was it felt a hell of a lot like lube, and your mother was rubbing you so thoroughly she was basically jerking you off.

"H-How do you know when to s-stop?" you gasped.

"Don't you remember the song? Happy birthday to you, happy birthday to you, happy birthday dear, John... Happy birthday to you... Oh I almost forgot, you need to do it twice for the full thirty seconds."

She started singing again. She was timing her strokes to the music, pumping your cock with each beat of the song. You were going to lose it. Your toes curled. When she reached the final 'Happy Birthday' you exploded. Your cum shot out and splattered onto the floor in front of you. You painted and slowly turned to face Jewel.

"Whoops... I guess I should have expected that. You are a healthy young man after all. Still, we've cleaned your penis but now the floor is all dirty. Wait here."

She fetched some paper towels and wiped your jizz off the floor.

"I'm sorry, hun, but this is the last of the paper towels. The shelves were empty by the time I got there... If your penis gets contaminated again, just tell me and I'll figure something else out."
