Of course.

Looking at his face, you know his answer before he even opens his mouth. When you made it sound like a test of bravery, the man couldn't refuse. Soon you were kissing him again, now with his back turned to the water. This time you kiss him more passionately than before, letting your hands roam his body as your tongues wrestle. As the kiss heats up you let one of your legs creep up one of his legs, soon followed by the other.

Suddenly you lean forward with all your weight and slam your heels into the back of your partner/victim's knees. He immediately collapses and tumbles into the water and panics a bit, but quickly calms down as he notices that you are still continuing the kiss. Because of his confusion at what is going on and his enjoyment of the kiss, it takes the man too long to notice that he is running out of oxygen. You now hug the man tight and entangle your legs with his while he runs out of oxygen and starts to panic. Seconds later he dies and his body vanishes into a grey light. Good thing too because you doubt you would have been able to hold him under for two more seconds.

Almost immediately after the man vanishes, you feel a rush of energy and hear a sharp PING sound, making you realize that you just gained a level. After a quick check of your stats, you're a little disappointed. You've gained a single level and it didn't get you any skills.
