After you think about this for a moment, you decided to stick with your him/her, even if s/he's a guy. As you quickly turn around and look at him, you walk towards to your former girlfriend, who is now your boyfriend, and hold his/her hands. "I'll stay with you no matter what if you still want me. Hopefully, I can cheer you up." you smile as you look at him/her.
"Of course, I still want you, hun. Even if I'm a guy, I still love you." your girlfriend/boyfriend replies as you both kiss passionately. "So, honey what do you think we should do next?"
"Lay down on your bed and let's make love," you answer him and give another kiss to him. As he's finally laying in the bed, you strip off of your clothes and reveal a big cock of yours. As he's looked at it, your girl/boyfriend couldn't hold himself and erect his big boner. "It's alright, babe. I'll help you out," you respond as you move to his cock and start licking your girlfriend/boyfriend's pink, hard cock. You then take a deep throat all in your mouth as your girlfriend/boyfriend moans loudly. Finally, your girlfriend/boyfriend couldn't hold you any longer, but just cums and release all of his/her seeds. "That was great, hun. Why don't you go for the main course?" he asked.
You then lube up and plow your girlfriend/boyfriend's pillowy ass, and again thinks about how much it resembled your girlfriend before she becomes him.
When you finally put your cock into his ass, you hear your boyfriend scream as he feels you inside her. "OHHH, YEAAAHHHH, HARDER, FUCK ME!" he yells.
You piston in and out rhythmically, harder and faster. And finally, both of you cum together. You then pull out of your dick and let your juices out in his ass and it overflows your girlfriend/boyfriend's ass.
"Well, I never thought I'd do that before. But it was awesome and pleasurable," you said
"Thank you for cheering me up, hun. It was the greatest sex I ever had," he replied.
"As I said, no matter if you're a guy or someone else, I still love you, babe." Then when you finish your sentence, you and your girlfriend, now your boyfriend kiss passionately and rest in the bed.
