Learning to bottom

I am waiting in the guest room with anxiety as Greg goes to his bedroom where he keeps the jar of Vaseline which he uses for masturbating and anal sex.
Wondering what'll happen, I conclude, well, everything that he's done with me so far has been sexually gratifying: Mutual masturbation, deep kissing, sucking cock.
Why not anal stimulation with a dildo? Or a few fingers?

"Relax, Tony," Greg tells me as he spreads my buttocks, "just a little bit of this".
"Ahhhh," I moan as he finger lubes my hole, "feels hot." Yeah, little fucker, I told you before: thats good! I’m trying with two and three fingers to geet your hole more loose, like your mother’s cunt... “Oooohhh, fuck... yeahhh...” I moan as he open wide my butt hole.
"Going to put the dong in, Tony. Won't hurt, promise."

Apprehensive, I hold my breath feeling Greg work the minimally lubricated dong past my asshole up into my poop chute. There's some resistance as Greg used hardly any grease telling me he didn't want to slop up my bottom with Vaseline.
In and out, deep in all the way up Greg toy plays my butt hole, making me squirm with joyous ecstasy.
“Ooooohhh, fuck, that hurts and feels so good... Don’t stop, please, get my arse used to your cock.
"Like it, don't you? Doesn't hurt, does it?"
"Uh, uh. Not like I thought it would."
"Can I bone your butt? Will you let me put my hard cock in your ass?"
"Yeah, Greg. . . . do it to me."

Greg pulls out his ass toy soon to replace it with his twitching erection.
The pungent aroma of my dildo-fucked asshole hits our noses.

Greg slowly rubs the tip of his dick around the opening of my loosened butt hole before slowly inserting his cock, with short stops to allow me to adapt to the girth of his phattie. In seconds he has his full seven inches inside of me. In and and out like the piston of a steam engine, with me moaning in pleasure from the feeling I sense.
Greg enjoys traveling his meat up my butt. Greg's balls slap against my butt crack each time he pushes his erected prick all the way in my ass.

After a while, Greg shooting a large load of mancream up inside of me, slows down his in and out movements . As he pulls his dick out of my butt, some of his warm sperm spurts out of my pleasured orifice, leaving a coating of jizz around my joy hole.

"Why not?" Greg says to me traveling his tongue around my crack to lick and taste some of his own ejaculate.
And that was my first lesson in the art of being fucked.
