Wanna hear something? Rivet would be really good to have sex with. Rivet not only has the familiar build as a human but has the genetics of a lombax which make it impossible to reproduce with meaning you my friend, can go ham as long as it is fine with it. Not only that but she has flexibility of an lobax so you can try every sex position with her without doing serious harm and she can fully recover in an instant looking at the fact she have been worn out in many fights and came back healthy right after. Rivet may have the ability to improvise which would make having sex even better since she could find new ways for sex in a matter of seconds. The downsides to this are that you cannot be too rough as Rivet has robot arm and powerful punches, so watch out! Not only does Rivet have these moves and genetics but she's more buffy than ratchet meaning she's like a tomboy gf you always wanted. She also has fluffy ears and tail which mean you can pet her from time to time! On top of that lombaxes are a group of felines based on a lion which gives them a probability of a breeding season which means lot's of sex in a certain time period! Overall Rivet is an amazing Character!
