Big payoff

River's inexperience is a turn on for you, since you are introducing an innocent to cocksucking. Her delicate mouth and tongue tentatively caress your hardness.

Kaylee says, "And now you should ...," but before she can say anything, River sucks your entire cock into her mouth. You groan aloud, bending over somewhat. "That's it. I was just going to say that," Kaylee continues. In a few more seconds, it feels almost exactly like the blowjob Kaylee just gave you. River replaces Kaylee's fingers on your chest with her own. Kaylee moves her hand back and squeezes River's breast through her shift. River moans around your penis.

You think the only thing better right now would be if River swallowed while she was deep-throating you. River takes you down to the root and starts swallowing. Her throat squeezes around the head, and you groan. She read your mind! Your legs are quivering from pleasure, and in ten more seconds of ecstasy, you say, "Here it comes, River. Eat my cum!" Your cock explodes, sending the first squirt of jism down her throat. Then River pulls back and sucks just the head as you deposit shot afters shot of hot, thick cum on her tongue. Kaylee shifts and cups both of River's breasts, kneading them and pinching the nipples.

You slump over, holding yourself up on River's shoulders. She pulls off your shaft, swirling your junk around in her mouth, tasting it. A small drip oozes down her chin. She swallows.

"That was interesting. Its texture is viscous, but warm. It is rather bland, but salty, in flavor. I will need more semen to test." River is very analytical in her statements. She leans in to lick your cock again.

"Wait. I can't come again for some time. But you're welcome to get more from me almost any time. You learn fast, and you're good."

"Ah, yes. I've read about the refractory period in males. How long is yours?"

"It depends. Half an hour or so."

You are about to put your cock back in your pants, when Kaylee leans over and licks the drop of cum off of River's face. She kisses River, getting as much taste of cum as she can from the teen's mouth.

"Maybe we can keep busy while you recover," Kaylee says with a sly grin. To River, she says, "Would you like to kiss me while he watches?"
