The food is laced!

Just when Jack was about to head into the living room he felt uneasy.

"I'm not feeling too good." Jack groaned.

Turning back, Nia questioned, " what's wrong?".

Jess looked at her husband Ben with a small cheeky smile.

"Should we tell them?" Jess asked Ben.

"Let them experience it, honey," Ben replied before pulling off his gown. Out popped his 10 inch cock and semi athletic body.

Now the whole family was naked.

Jack threw a furtive glance at his father before he turned to speak to his mother. While this happened his cock was beginning to buck and twitch uncontrollably.

"Mum, what's happening?" He cried pitifully.

Giving Ben a look and then looking at her son, Jess decided to ease his worries by explaining.

"Me and your father forgot to mention about the food here having certain 'effects'. Basically it means for you men having to cum more frequently."

Clutching futilely at the tip of his cock, Jack weakly looked at his mother as he spoke through clenched teeth. "But... Why isn't dad affected?" Up until now, apart from being erect, his dad was still acting normally. It was frustrating.

Ben, enjoying the plight his son was in; while remembering his first time, finally spoke. " Son, don't worry. Since you're new to this place things will be like this from now on. I had this happen when I was introduced to certain foods here. It still happens from time to time but it takes a greater amount to affect me now." Finishing his talk he laughed.

Recalling those past times Ben had a happy smile on his face as he absentmindedly stroked himself. Jess didn't flinch as she saw this, but Nia couldn't help crossing her legs and looking away. As for Jack, seeing his dad getting aroused made a grimace form on his face, but reminded of his own problem he couldn't care less now.

"Oh hush you!" Reprimanding her husband, Jess moved to her Jack's side before hugging him.

Feeling the heat of his mother's body alongside her soft breasts, Jack shuddered as he felt himself cumming. The euphoria from his balls draining made him uncover the head of his cock. It sprung free, now spilling the floor with his seed. Jack cried as he felt a hand grip the base of his cock and give it a pull.

"-Mum! What're you doing!" Jack tried to pull away, but his mother held on tighter.

"Stay still, I'm helping you." Jess looked at her son sternly while she continued to help him empty his sac.

Pretty soon there was a large puddle of semen on the kitchen floor. Thankfully, a robot from god knows where had come out and cleaned it.

Smiling at her son, Jess let go before patting him on his head and broke the hug. " Okay, now let's head into the living room to discuss things.."
