After work, we met up at the Donki parking lot and headed to a hotel. My girlfriend mentioned there was a slutty senior at her part-time job, so we decided to go together as a threesome. Though we'd only just met the senior, we started kissing shortly after arriving at the hotel and completely ignored my girlfriend. The senior turned out to have surprisingly large breasts with pink nipples and smooth, silky skin. My girlfriend has piercings on her nipples and tongue, and she's a total sadomasochistic freak. She was clearly turned on by the threesome, eagerly licking the senior's breasts together with me, then having both of them lick my hard cock. I made my girlfriend give a rimjob while the senior gave me a blowjob. We didn't even bother showering, but it felt too good to care. My girlfriend loves swallowing cum, but this time I decided to creampie the senior's mouth instead. On a whim, I asked the senior to masturbate for us, so she started touching herself right in front of her junior. The excited junior began sucking the senior's tits, while I soaked her pussy with a vibrator. The senior climaxed hard, intensely orgasming from simultaneous stimulation of her clit with an electric massager, her nipples, and the vibrator inside her. I lined up both girls and took turns fucking them. After thrusting into the junior's pussy, I'd pull out and have the senior lick my cock before plunging back in. The back-and-forth fucking was amazing. Since I'd already creampied the senior's mouth earlier, this time I came inside the junior's pussy. Still rock-hard and unable to calm down, we immediately started round two. Finally, I lined up both their faces and facialized them together. Maybe next time I'll fuck the senior one-on-one.
