Edwin and Portia both have pretty high drives... so they fuck. A lot. all the time. Everywhere in fact. They just really like each other, and like to show that quite a bit.
I think edwin is everything portia want's and more, and is prob the first person she's really compatible with/checks off all her boxes. I think the same is said for Edwin. Once they're dating, Portia is much nicer to him outside the bedroom, while being a lil mean inside the bedroom for him cause he likes it. Edwin's a lil mean outside the bedroom, but inside is more of a puddle. He def doesn't get to be in charge often, but when he does he's p loud and annoying lolol.
Edwin is kinda a quick fire, but he can go for MANY many rounds, he just needs a break every so often. Portia has the endurance, but once she's done. she's DONE, she's out. Edwin likes to bone to wake up, Portia likes it to sleep, he probably gets a quickie in before he goes to work, and she goes back to sleep while he leaves her coffee and breakfast for when she wakes. She comes home from a late shift at 2 am and gets that man, promptly passing tf out after the fact. He def has fantasizes about fucking her in his work van. Edwin's life is pretty great, he goes to work, his waifu packed him lunch, sometimes if he's working nearby she will come have 'lunch' with him, aka a roll around the van, before sending her home where she takes a nap before she goes to work. Edwin is a nap girlie, he absolutely makes portia a nap girlie.
