See if she'll let you use her mouth
From Create Your Own Story
"Are you serious?" She asks, looking a bit confused and a bit insulted. "You want me to get up and let you cum in my mouth?" She sighs as you nod sheepishly. "God, some things never change." She steps over you and gets up on the floor, puts her hands on her hips. "If I let you, will you just go to sleep afterwards?"
"Of course," you say.
"And we don't talk about this again, or bring it up even? It's a one time thing, you got it." You nod again. She sighs. "I can't believe I'm doing this," and she gets down on the floor on her knees, sits up straight, and opens her mouth up wide.
You get up too, positioning yourself so that the head of your cock is nearly touching her lips. You stroke, faster and faster, watching her semi-annoyed face, but reveling in the moment to come. Your hot load spurting into her waiting mouth, dripping down her throat, over her chin. You pound faster and faster at yourself, breathing hard. Melanie rolls her eyes again, then slaps your leg. "Come on," she says. "Hurry up."
"Fuck, I have to concentrate," you say. "Just give me time."
She rolls her eyes yet again, sighs, and then flutters her eyes at you. "Come on baby, I need your cum in my mouth." Suddenly, you're back in the moment. "Come on. Shoot that hot load all over my tongue. I need to taste it."
That's all it takes. You spurt your hot load right up onto the roof of her mouth, and she takes every drop. Stream after stream shoots from you and you feel like your knees might buckle watching her take your salty semen. When you're done, she swallows, then points to the bed. "Now, can we go to sleep please, you ass?"
You nod in agreement. Right now, you'd do anything she commanded. You crawl onto the couch, nestle into her, and drift off to sleep.
