You stop sucking

You pull Mark's cock out of your mouth and look at him, waiting for instructions.

"I hoped you'd choose to stop", Mark says. "Now lay on your back on the sofa", he continues while standing up and getting out of your way.

You also get up, turn around and lower yourself on you back onto sofa, while Mark positions himself directly in front of you. You are already mentally prepared for him taking your ass, when - to your surprise - he gets on his knees.

"Put your legs against my shoulders", he tells you. You do exactly that and rise your legs, placing them on his shoulders.

You're not sure of what Mark has in his mind, but your confusion is quickly dissolved as he bends towards your ass. Shivers go through your body as you feel Mark's wet tongue pressing against your asshole. You've never really thought how it would feel to have someone eating your ass and now that it's happening, you're positively surprised.

While continuing to eat your ass, Mark first pushes one finger into you, quickly followed by another. Slippery with all spit, your ass lets his fingers enter surprisingly easy. You enjoy the attention Mark's giving for your ass, even letting out few moans.

"Haha, I think you're ready", Mark says, after you let out a particularly hard moan. "Now stay still", he tells, as you feel his hand spreading the lube.

"So... I know you said that condoms are must, but would you still consider trying it without?", Mark asks you suddenly, while already taking position to enter your ass. "I'm clean so you don't have to worry about it, and it's so much better without...", he continues.

As you consider your options, Mark slowly fingers your ass. You feel like going without condom is an unnecessary risk, but on the other hand, idea of losing virginity to bare cock excites you.
