Me & my gf have this pact. If one of us is in the mood, you don't have to ask you just take it lol. The whole apartment building had a blackout by the time I arrived home. I've been hard the whole day from sexting back and forth with my gf. As soon as I walked into the door I let out a sigh of relief before heading to the bedroom where I saw who I assumed was my girlfriend bent over, head inside the washing basket, the light from her torch wasn't bright enough for me to take in all the details but I could tell she was wearing a skirt.

I walked over, spanking her ass and grabbing it. Listening to her soft chuckle. She remained bent over, I went down my knees, pulling her panties to the side and slid the tip of my tongue inside her pussy. Instantly, she became wet. I start licking and sucking on her pussy while her muffled moans sounded from where her head was at. I took off her panties and started tongue kissing her wet pussy slowly, adding gently bites. Then started using my hand to pat her clit gently before rubbing on it. At that point her screams were getting louder. I rubbed on that clit, my tongue pushing against her pussylips licking her insides. I could tell she was ready for me.

I stood up, pulling her upper body from the basket, allowing the light from her phone to flash her face. I was shocked, it was my girlfriend's sister, she giggled. Sliding her hand down my throbbing hard cock, using her thumb to rub the tip, she leaned in and whispered "We might as well finish", In that moment, she went down her knees cradling my balls and licking from the shaft to the tip, took it all in and looked up for approval. I could feel my toes curl from the blow job she was giving me. Her hands moving behind me, grabbing my ass when she deep throats and gags.

I was about to explode, she gave me a reassuring look to finish on her face which I did. Now it was my turn, I bent her over, made her touch her toes. Without warning she yelped and moaned when I stuck my thumb inside her ass and start fingering it. I positioned my dick in her wet pussy, pushing it in. Feeling how tight she was, I let out a surprised moan. Slow strokes, increasing pace when I started fucking her. My thumb still inside her ass, I'd occasionally spit on it. And started fucking her fast and faster, feeling her pussy vibrate from the trouble penetration. Her legs shaking, I knew I'd hit the spot. I placed both hands on her waists and fucked her harder, until her body shuddered from an orgasm.
