Baby, you've done great for your first time. Yet, you don't seem to be so eager to go further for me... when i've given you choices, you let me down. So, no cumming for you today!
But there is something you can do, if your balls are really too full... Do you know about ruined orgasms? That's when you stroke over the edge, then, as the cum starts flowing up the shaft, you put your hands away, and provide no further stimulation to your cock... the cum will leak out, but you won't feel the pleasure you'd normally get!
Or, since you don't like to eat precum, you have to eat your sperm... stroke and cum as always, but get it all in your hand and then lick it up! You'll see, it's not so bad...
The choice is yours, baby... one of the two, or put it away and no orgasm. Next time, you'll do better, i'm sure!
