Give her a creamy treat to swallow

Right before you let out your semen, you take yourself out of her with a loud POP. You move your twitching cock to her face. Her eyes are hooded, but quickly light up in realization of what you want and envelops as much of it into her mouth as she can. Her blowjob skills could certainly use some work, but her enthusiasm is more than enough for your sensitive dick and you just barely keep yourself from thrusting as far down her throat as her can once you start cumming.

Meanwhile, she uses her fingers to stimulate her clit and it isn't long before her hips start spazzing out as an orgasm rocks her body, causing her to squirt her essence out in a wide spray beneath her.

Once the last shot of cum has fired into her mouth, you slowly pull out from the tight seal formed from her lips. She takes a moment to savor the taste of your semen before swallowing the load on her tongue and then opening her mouth to show you.

"Mmm, you taste great, Red," she says with a dreamy look on her face.

Eventually, you both get up, and you place your junk back into your pants. You notice Blue's sister looking down at the puddle of her juices on the table. "Well, I guess I should clean that up giggle." She walks over to you with a lustful smile on her face and places her hand on your chest. "I hope you have a good time Red." She pulls you in close. "And don't forget to visit." She ends the conversation with a quick kiss on your cheek.

Feeling you have accomplished everything you wanted here, at least for now, you head on back outside to Pallet Town.
