cum exchange

Cumming into someone else's penis and inside their balls, therefore "filling their natural reserves", akin to a transfusion. This can be done either directly through urethral_penetration (usually penis_in_penis) or through intermediate tubing (possibly a urethral_tube) connecting both penises.

Normally involves cum_inflation, ball_inflation and cum_inflated_balls, though inflation is not a requirement; it just makes it plainly obvious that this isn't merely cum_in_penis or cum_in_bladder.

Can lead to spermicidal takeover or testicle impregnation, though neither should be tagged without additional information, such as a cutaway panel showing sperm cell collision.
