My gf [F26] made me [M29] fuck her in her ass while she wore a little red riding hood outfit. [Str8]

First a bit of background. We’re a professional couple, and probably to outsiders seem very much like your everyday happy vanilla relationship type duo. She’s around 5’3 with a petite build, blonde, shapely, busty (with nipple piercings) and an amazing thick round ass.

This was last night. We’d been having a few drinks and playing a few dirty truth or dare games online, going into detail about what we’d do to each other and generally winding each other up. (She loves to wind me up, its genuinely one of her favorite things to do). Because she came on her period a few days ago, we knew sex was off the table, which made the sexual tension 100 times worse. We’ve only ever done anal a handful of times (usually after a lot of drinks when weve been super horny) and isn’t generally something she instigates or goes for. The tension was driving us mad, with us both quite visibly teased and aroused. She kept telling me how badly she wanted me inside her, and eventually she went into the bedroom. Side note – later this month we have an event coming up in fancy dress, and she’d bought a little red riding hood outfit. She called me into the bedroom and as I wandered in, I realized she’d changed into it. She looked stunning in a completely innocent, but naughty and sexual way. Her boobs looked huge, and she was turning around and wiggling her ass in my face, giggling, knowing exactly what she was doing to me.
