Imagine yourself being a teenage boy and having two teenage sisters who enjoyed having unprotected sex with you at the same time in the privacy of their bedroom. Then imagine shooting your cum load in both of them so they wouldn’t argue about who was going to get your “love juice”. My wife was very adamant when she said that she always tried to get her brother’s cum load first before he finished cumming in her sister because the first few spurts were the largest of several that he could ejaculate.
