Can't stop now

Seeing Katy Perry in front of him Zack immediately tries to go for her boobs. This does not suprise you, but when he touches your chest he gets a confused look on his face. Apparently your command didn't affect his other senses. Thinking quickly you push him back "Easy tiger, let me do something for you first." You push him onto the bed and tell him to sit while kneeling in front of him. For a while you admire his hard cock, jerking it gently. Briefly you wonder how far you should go with him but seeing his cock inches from your face is just too much. "I bet you've dreamed about this." With that you lick the tip, the taste of precum is intoxicating and you quickly takes his cock as deep in your mouth as you can.

Zack is in heaven having his cock sucked by a star, and he streches back, gasping for breath. Part of you thinks this is wrong but you've been so horny ever since the experiment that there is no turning back now. You jerk your own cock while blowing Zack and eagerly wait for him to blow his load. "I wish he'd cum hard in my mouth." Immediately Zack warns you that he is about to cum and you feel the first spurt in your mouth. You try to swallow as much as you can but Zack doesn't seem to stop and you have to pull back. Finally you go over the edge yourself and start cumming as you fall on your back. As you gasp for breath Zack does his best to cover you in his jizz. Opening your eyes you see that your chest is covered in your and Zack's cum.

Both of you are breathing hard, but while Zack is basking in his post-orgasmic ecstasy, you start to panic, filled with conflicting emotions. You have deceived your best friend and taken advantage of him, athough he didn't seem to mind the experience. On the other hand, you have never been this horny in your life. Briefly you wonder if you should tamper with Zack's sexual preferences, or just make him forget this incident. "Umm listen you look like you need a shower and umm... When my roommate comes back would you like to invite him to bed as well? That would be so hot." (As if you didn't feel guilty enough already.)

Maybe you should make this up to Zack somehow? With shaky legs you head towards the shower Zack following you like a puppy. Actually, more like a horny hound.
