The girl stood back and cleared her throat."You need me to relieve you?" She asked my sister quietly. Becky stared at me as she responded."No, my assh...le boyfriend was just leaving." She challenged me, kneeling in front of the hole."Like hell I am, not while my cocksucking girlfriend is still here." I shot back, not budging an inch."Fine, watch if you like, pervert." Becky looked up at the tall girl and told her to send the next guy in. Not wanting to be a part of this at all, she walked around. Soon I'm in a frenzy and don't give a fuck, pounding her asshole with a slap-slap-slap sound.I'm close to exploding thinking about how hard I'm dominating this bitch. I want to fill her asshole with cum but think better of it. I pull out and spray the biggest, thickest load of my life all over her ass. I make sure to milk every last fucking drop out then go and wipe my dick clean all over her beautifully done up hair and face.She looks really hot right now. Lying on her stomach fucked to shit. After kicking myself for a while, I settled down and did my best to live with the decision. While I felt uncomfortable, Kay and Paula didn’t seem to be affected. They were both excited about something and broke the news, Kay’s mother was coming for a visit next weekend! My discomfort level went up another notch. Why was that? It wasn’t like I had slept with her daughter? It’s been years since I met a girlfriend’s mother, and Kay wasn’t even my girlfriend!Oh, I remember the first time I. It had an unmistakable taste & texture, it was salty & thick, I opened my eyes & they confirmed what my taste buds were telling me, a thick load of white semen was oozing from her vagina, my legs buckled & my pussy throbbed as I realised I was licking, tasting & swallowing my own sons semen from his sexy Bisexual girlfriends pussy and in total amazement found my tounge burried deep inside her tight pink arse as another load of cum oozed out from deep inside there as well. My mind went back to.
