I’ve been doing it for years. Lay on the floor. Scoot your butt up to the edge of the couch or whatever. Jack off til your ready to cum and scoot your butt up the side of the couch or whatever. That’ll make it easier to end up with your legs over your head. Then let the cum start but not blast out. You’ll be able to take the whole load down your throat. You’re welcome🍆💦💦💦👅
