Fuck her like it’s your last fuck. And hers. Fuck her so good, so hard, so wantonly, so profligately that she is left a quivering, sparking mass of shaking flesh and sex fluids. Drain her of everything, then drain her some more. Kiss her all over, make love to her all night, and hold her close in the morning. Own her body, own her gratitude, own her love. If you don’t know how, learn to give her squirting orgasms.
