My sister came over to wake me up and when she pulled back the covers, my dick was rock hard and standing at attention! It had been a while since I last got an erection like this, so my horny, frustrated sister couldn't help but rub her wet pussy against my morning wood. She tried to be quiet about it, hoping not to wake me up, but then I stirred and she impulsively slid right onto my cock, giving me a surprise bareback fuck and creampie! Things escalated even further when my sister, unable to control herself any longer, started riding me slowly in reverse cowgirl position, making sure to hit all the right spots as she experienced multiple powerful orgasms! Seeing how turned on she was by my morning wood, she became increasingly uninhibited and aggressive, transforming into a completely different woman before my eyes!
