As long as he doesn't enter you...

As your hand begins to move back and forth, so does his dick. Feeling it glide against your skin feels amazing, especially when he moves back enough to pick up some of the juices from your dripping pussy and brush your clit. The first time it happens, you can't help arching your back, pushing your chest into Alex's, while you moan into the kiss. Amidst the lust clouding your mind, you're still aware you shouldn't be having sex. But some "dry" humping should be fine, right? As long as he doesn't enter you, you can't get pregnant. And what you guys are doing right now does feel pretty fantastic...

You feel a jump in your stomach as Alex's hand gently travels along your stomach. Your sweatshirt must have gotten a little pushed up somehow. You pull away from the kiss, afraid he is going to try to enter you. "Alex..." You start to say when Alex surprises you by gently grabbing your wrist and dragging it back up your body. You're so shocked you don't resist him at all as he leads your hand under your sweatshirt up to your breasts. When your hand makes contact with your sensitive nipple again you can't help letting out a loud moan. Distantly, you feel Alex smile into a kiss onto your neck. You don't know when he moved to there, but since it feels so good you decide not to say anything.

Alex has lowered himself onto you a little. He isn't crushing you but leaving you with just the right amount of heat and breathlessness. This new position also allows him to grind his hips directly between your lips instead of on your lower stomach. He is hitting your clit on every stroke now and you can feel yourself moving your hips with his, seeking that delicious friction as your juices thoroughly coat his dick. At this point, the voice telling you to be careful is a small whisper as you begin to lose yourself from the sensations on your neck, nipples, and pussy.

It is at this moment as you begin to approach the edge that you feel something completely different and so much better. The combined movement of both hips, the wetness of Alex's dick, and your relaxation as you submitted to his ministrations has allowed Alex to accidentally slip inside. You both let out a long moan as he reflexively jerks and sinks halfway in.
