Did my guy just say he has a bigger back-up penis?! Lol One penis to prepare the body and a bigger second penis to fertilize the egg. It's a good thing Thermos are primitive and subjective . Can you imagine people trying to exploit them for sexual favors by requesting the penis they wanna have fun with that night? "I missed you all day, so I want you all night. I love the stretch of big daddy, but I wanna play with the younger brother today~♡" lol
