Surprise in the morning
From Torg Adventure
You shuffle back to your room, crawling down the ladder, and locking the hatch. You need to sleep a long time after the exertions you've made to please Kaylee and River. You flop into your bunk and instantly fall asleep.
Amidst dreams of Kaylee and River with Inara occasionally making an appearance, you wake to a mouth on your cock, sucking you to fullness. You groan and open your eyes, and the first thing you see is an open air grate in the ceiling. You look down and see River's head bobbing on your johnson.
When she feels you move, she stops and looks up, her hand stroking you perfectly. "I must analyze your physical responses and your ejaculate. Hold still while I perform fellatio on you." You notice her face is covered in fluids, and she has the strong scent of pussy about her.
You chuckle.
"Did I say something humorous?" River's face doesn't show any emotion.
"No, but I think you've been analyzing Kaylee's physical responses this morning too." You grin at her.
"Yes. For 87 minutes after you left, and for another 52 minutes this morning. Her psycho-physical reactions are much different than yours are. The chemical composition of her fluids is different also."
Your mouth drops open. River went down on Kaylee for an hour and a half after all the sex last night? And another hour this morning? Kaylee's going to be sleeping a lot today, you'd guess. You groan as River sucks your cock into her mouth expertly.
Remembering what River did last night, reading your mind and adjusting her technique, you replay memories of all the best blow jobs you've ever had. In just a half minute, River is sucking your cock like the best of all of them, her tongue twirling, her lips sucking, and her head bobbing up and down. She keeps this up until the second you feel your balls start to tingle. Then she takes you all the way down and swallows repeatedly, the back of her throat gripping the head and squeezing it. You grab her head as your hips pound your cock up into her mouth and you unleash a torrent of hot cum into her mouth. Your shout echoes off the walls of your room.
With effort, she pulls back, holding just the head behind her lips, letting you fill her mouth. You pant hard, recapturing needed oxygen.
You look at her as she takes her mouth off you. She swirls her mouth around, tasting your juice. She has a thoughtful look on her face. After a minute, she finally swallows your load.
"I think I have achieved the perfect technique to generate the best response from you. The chemistry of your ejaculate still eludes me, so more tests will be needed." Her voice is flat when she says this.
"You can test my ejaculate any time, River. You're the best cocksucker I've ever had," you say between gasps.
"Fellator is the more grammatically-correct term." She dips her head to lick a dribble of cum from your shaft, which quivers and starts getting hard again.
What happens now?
