I latched onto one of her nipples with my teeth and began to suck a bit harder than I had during the first time. Her body began to jerk, and her walls...began to spasm, signaling the start of her orgasm. I didn’t relent and instead tried to pick up the speed and force of my thrusts, as well as move to the other nipple. I moved my hands to her ass, sinking my fingers into the taunt flesh, enjoying the springiness of her posterior, as I continued my assault. I could feel the juices of our coupling. I was enjoying his ride. After sometime I request him to fuck me in dog pose and he was ready for that. I was bending like a dog holding the table and he was forcing from the back. During this process he was smoking my ass which I loved the most. Finally we both cummed and the party was over. Meanwhile our experiment was also going on. We then dressed and started to note down the result. We locked the lab and came out of college. We went to a bar and then we drank. We were fully drunk.We didn’t. You groaned as my hardness pushed deeper into you, and I felt you relax as I leaned into you, feeling my thickness fill you as I pressed you up against the window. I grabbed your hips with both hands and slowly pumped my slippery shaft within the warm tightness of your asshole. Looking into my eyes you pushed back towards me, coaxing the warm pressure of my cock deeper with each thrust. I eagerly pushed deeper into you, and watched you pull down the top of your dress to press your exposed. I could feel a wet spot of my own in my pants when I saw how wet her pussy was. It was drenched; I could see her juices literally dripping off her clitoris and onto the bed sheet. I noticed that hadn’t shaved and it made me want even more to bury my face into her snatch. Hers was the kind of pussy that just the right amount of fuzz makes it look naughty. Abandoning all pretense I took two fingers and slid them slowly into her pussy, glorying in the feel of her warm tightness. She moaned softly.
