make him cum fast butdon´t stop after his orgasm, keep going as hard and fast as you can, try to make him cum a 2nd time. maybe he hates you, while you are doing that, but be sure when he is done, he will loves you more than ever! And no matter if it was a normal or ruined orgasm it is the same for him
This is actually how I cum every day... Rubber under balls, nice silky black stocking(holdup) on cock, and teasing and torturing myself, and finally cum inside that stocking! After that, washing stocking, and stocking is ready for round 2 or for jerking into that tomorrow...
