He has his suspicions

Based off the animalistic grin that the incubus was sporting as he fucked the frothing at the mouth succubus beneath him, you could see that he was catching onto something not being quite right with both your actions.

"Well?"

Sporting a devious smile with a knowing look in his eyes, you just know he's enjoying playing games with your emotions.

"What should we do..."Looking over at your mother, you find her absently watching the obscene play happening out in front of her. This was not the time to be freezing up.

Keeping an eye on the incubus, you edge closer to your mother to tap her on her smooth shoulder. Leaning within inches, you feel the warmth of her naked body radiating out towards you like a fire on a cool night. Quietly, you whisper in her ear cautiously and awkwardly.

"Mom! I think watching them is affecting us.... physically." Spooked at your close proximity she shies away slightly, before moving back to her original position before eyeing both your current states.

Even though your mother's face has changed to look more exotic and mesmerising, you can still see her thoughts clear as day as she tries to think of a solution. Some kind of struggle is warring within her as she tries to come to terms with what she's decided on. One thing that hasn't changed is her subconscious need to fidget around when she's mulling something over. Normally this wouldn't be a problem. But now, with both of you being naked and you specifically sporting a more than 'usual' erection inches away made the inevitable scenario of her skin brushing against your oozing monstrosity.

Stifling back a groan, your cock betrays you as it twitches in response to that silky touch. Blood further invigorates it, making a mixmash of pulsating veins throb along its abnormal length;clear as day to the naked eye.

If you can follow this process, she can too. Sneaking a glance, you can see she's looking down at your bedevelled cock. Her eyes seemed almost entranced, watching it writhe and spit out its contents at having being teased. The virus must've affected her also, her body was responding in tandem with yours. Her nipples were as hard as steel, like two red cherries, and there was a slight wet trickle that was parting at the gap between her creamy toned thighs.

"Hello?"

Jumping at your churlish whisper, a guilty frown quickly flashing across her face.

"S-orry. I-Im still out o-of sorts..." Shifting her gaze up to your face, she flashed you a helpless smile." Just follow my lead...okay? We'll get through this in no time." As she was speaking, it still didn't dispell the hungry gleam in her eye from showing, but you were happy enough for her motherly concern for you to return.
