How i found out [M] (19) that my gf [F] (18) is slut

Before we started having rough sex we always had passionate sex and nothing extra like slapping etc but one day i was watching porn and i found video where one guy fucked girl very rough and it turned me on a lot. I asked my gf if she wants to try it rough and she agreed, we talked about it and when we had sex i choked her little bit, slapped in face etc and we both loved it. We started talking about rough sex more and more and we always tried new things in bed. She told me that she wants to be used and fucked like a slut and this is the best part because we enjoy it a lot and i like to tease her until she begs for my cum and asks me if she’s allowed to cum. If she does something bad or won’t suck my dick fast i’ll slap her and tell how big slut she is and i start fucking her like cheap whore and she loves it. I love when she wears lace underwear and sexy clothes and i’ll tell you story when we had best sex ever.

It was normal day and she invited me to come over when her parents leave. She always wants rough sex since we tried it and wants to be my obedient slut so i decided i’ll surprise her. When she opened door i washed my hands etc and then i unexpectedly grabbed her neck from behind and with other hand i started touching her amazing body. She was breathing very loud so i teased her little bit and then i threw her on bed and told her to suck me, she sucked me like never before but she stopped for a second because she wanted to kiss me but i punished her. I slapped her tits hard and deepthroated, i wanted to lick her pussy so i undressed her and her body looked so perfect in red lace panties and bra, i told her to play with her tits and i took off her panties with my mouth, she never had so wet panties and pussy, i licked her clit and then i fucked her doggystyle, while i was fucking her rough i put her wet panties in her mouth and pulled her hair, then i put dildo inside her mouth instead panties and this was so hot, i spanked her ass multiple times and told her how cheap slut she is etc and we loved it. She had so intense orgams her eyes were rolling but i told her to be quiet because she is my slut and she must do everything i tell her. When we finished i cummed inside her mouth she swallowed and her legs were shaking she couldn’t even stand! We cuddled little bit and then fell asleep in hug
