You allow your body to react to her

Her pussy glistens with moisture, and a milky drop of her cum has oozed out and dribbles into her butt crack. You get up close to her until you can rest your penis on her tall belly. She grins at you as you look into her eyes and begin to rub your penis up and down on her skin. You close your eyes and allow your body to react to her, allow yourself to become stimulated.

You smell the scent of your sex together. You feel your penis slide along her pregnant belly on her sweat and your pre-cum. "Yes, just like that John, just like that." Karen says quietly, encouraging. Finally you feel it welling up within you. The fluids in your body are mixing together with your sperm and begin pulsing through your tubes.

With a grunt, you release a spray of cum that splash across her stomach and breasts and into her eye. She blinks in surprise as you let out another volley, a rope of cum that spills between her breasts and all over her belly. You grunt again and slide your penis across her stomach, through your own cum, building up stimulation to spur two more pulses of cum that pour all over her belly and dribbled down her body.

A few, smaller gushes ensure that her belly is glistening with your sticky cum. You groan happily and move back and lay on your side next to her. Karen just smiles, looking down at her cum-covered skin, while Andrea is running her fingertips through what is pooling where her stomach meets her breasts. Andrea smiles at you and leans over. You kiss deeply again, happy that you could help the young pregnant Chinese girl.
