While sucking his dick, you too let your mind relax. After a long while of licking and slicking the cock, you feel it growing and twitching again. He is about to cum. Before your mind can react properly, your mouth is filled with glooly slime.
Your head, the centre of your perception, thoughts, and feelings, penetrated by your friend, is now pumped with his semen, his very dna. And like every blowjob you wonder: spitting or swallowing? But his huge dick does not leave much of a choise. Your mouth still being filled to the brim with cum, you can only gulp his seeds down your body, the rest of your body filled with his fluids.
He breaths out a moan and falls down into your arms. Buried under his much more muscular body, you lick the rest of semen from your lips and rest.
After another hour, you decide to shower, dress, and leave. A lot of things happened you need to process. You got feminzed, turned into an emo girl, got facials, and now had oral sex with one of your friends. Thats surely a lot of changes you need to comprehend.
