"Hurry up in there. I really need to go." Zoe banged on the door again.
"Alright." Jon responded. He quickly threw open the door, not thinking about how she might react to him trying to hide his boner.
"Oh." Zoe stopped in her tracks. Her eyes were glued to Jon's crotch. She could see his stiff erection through his jeans. She breathed out in sexual approval. Then she seemed to take a long inhale, seemingly tasting Jon's arousal in the air. His little sister started to blush moan and her pupils grew in size. It was like she was entering a type of heat just by smelling his arousal. Would that happen to him too? "Well dang bro, why didn't you say anything? I'm always ready to help you out. You know how I like you best."
Zoe immediately knelt down in front of him and started to unbuckle his pants. She lifted her black and blood red skirt and started to finger herself in front of Jon before he could even protest. Her second hand was already bringing her black frilly panties around her ankles. Her mouth continued to move, unzipping Jon's pants with just her teeth. Jon's penis was straining against the fabric of his boxers. She fished his dick out using her tongue and lips, the hand with her panties bringing Jon to her face as she squeezed his ass. Her long breaths came in more forcefully now that her nose was directly in his crotch. Jon was bewildered, not only was she okay with this, but she seemed to crave it. She started to slurp her way along his shaft, her tongue dancing around his head. He was so far in heat, and she was surprisingly good at giving head, that he easily blew his load down her throat. She deepthroated him as soon as he started to spew his milk inside her mouth. She moaned and feverishly twiddled her clit and shook with climax herself a second or two later. She gulped down everything, not a drop was wasted. She licked up and down his shaft to make sure that it was all gone. She opened her mouth to him and showed him that it was empty. She had drunk everything he gave her. He was so flustered that he couldn't even react or think about what he had done with his sister. What she did to him. She stood up again and kissed him, her tongue easily wormed its way into his unsuspecting mouth. He could still taste his own seed on her saliva, which he seemed to like for some reason?
"Wh-" Jon began but he was pushed aside as Zoe dashed into the bathroom to relieve herself. He just shook his head and headed down stairs. He was going to see Karyn and talk with her about his wish. Since he could reverse the wish, anything he told her would be forgotten as soon as he reversed it.
"Oh Jon, just the young-man I wanted to see." He heard, descending the stairs. Oh no, Jon certainly didn't want to find out what his parents were like if they treated sex just like a kiss. They would kiss him every time they caught him leaving the house.
