I was dumbstruck, lost. What was going on? The last thing I actually wanted to do with Lizzie was homework. I wasn’t ever keen on homework. This was... why Lizzie and I weren’t in any of the same classes; she was a straight A student.She studied my face, bemused. “You haven’t worked it out yet, have you?” she asked me. I sat in silence, trying to work out what it was I hadn’t worked out yet. “Mondays my mum goes to bingo and gets home just before 5. Every day your mum gets home from work 40. . "Unnnhhh! Unnnhh! Fuck meee! Yes, fuck me hard you big bastard! Christ, what a cock! fuck I love your cock! Uhhhhhggggghhhh!" Spasms of erotic sensation rippled through the precocious sixteen year old as she continued to watch, glued to the incredible scene. One of her hands drifted up to caress the plump, roundness of her young tits as she watched and listened to the provocative sounds of her parents fucking. Her other hand crept down under the waistband of her panties to the prominent mound. “Now it's your turn. You must need to go too don't you?” I nodded and looked into her eyes as I let the pee flow all over her face and hair. She opened her mouth a little to catch some of the pee which she then dribbled down her chin. Having made quite the mess of ourselves and the bathroom we mopped up the pee before taking a shower which lead to us fucking with the water flowing all over us. We then spent the rest of the afternoon trying out sex in various gymnastics positions and nearly. What I said worked. He took a deep breath and quickly picked up the pace and began pumping my pussy nice and hard again.His thrust was harder each time Ernesto smacked his balls on my clit. I was starting to enjoy his passion when his pumps finally stopped and he collapsed on top of me pulling me to fall on my side with him on the floor. His hard dick was still inside me and we were spooning on the floor, both breathing heavily. My pussy felt hot with his cum inside me.My senses were slowly.
