Very Well

Tony let out a small gasp as Katie's tongue touched the base of his member, before slowly moving to the very tip. "You're adorable," Katie giggled. Tony was about to protest, when Katie's mouth fully enveloped the head. Another gasp escaped his lips, causing Katie to smile around his dick, before beginning to bob her head up and down on his shaft.

"Oh god..." Tony managed to murmur as his brain started to melt. Katie looked into his eyes as she slowly lifted her head until his penis popped out of her mouth, then she playfully ran her tongue around the head.

"Enjoying the lesson?" Katie asked, before resuming the blowjob. Tony could only nod. Katie began to speed up her movements, causing Tony to grip the cushions tightly to avoid blowing too early. Noticing this, Katie slowed down, barely moving her head, instead letting her hand do all the work. As his brain slowly resumed functioning, he noticed Katie stroking her much larger shaft in tandem with his. It might have been the person it was attached to, or it might have been that he was currently receiving the best blowjob of his life, but seeing her jerking herself off was somehow making this even better for him. He attempted to look away, but that only led to him seeing his best friend, now girlfriend, sensually licking and stroking his dick. He could feel his orgasm approaching.

"Katie, I.. I'm..." he stammered. Katie's hand moved at top speed as she began to move her tongue around rapidly. He felt his dick begin to twitch as Katie continued her high-speed ****, and began to cum.

As soon as the first jet began to shoot from his tip, Katie took him in her mouth as far as he would go, and Tony moaned as he fired directly into her mouth. This was enough to send Katie over the edge herself. She pulled back as she let out a small scream of pleasure as her own orgasm hit, firing several jets of semen upwards, some of them landing on Tony's crotch and legs. As both of their orgasms came to an end, the two lovers looked at each other.

"Well?" Katie asked. "Learn anything?"
