Tips on increasing sperm retention?
 

Would like to know any tips on increasing the size of my load

Better overall health and some extra zink in your diet.

Try using one hand to clamp down as hard as you can "2 fingers" on the base of your dick then jack off as hard and fast as you can with the other while your getting your dick sucked .. Continue until you feel like it's gonna explode ..

Actually, you might want to try it out first , see how it works out for you. Next time pull it out of her mouth and talk dirty ..she gonna be rolling her eyes thinking you not gonna be shooting much of anything anywhere and the look on her face as the 3rd and 4th steam of cum hits her in the face should be priceless..
