Of course. You wouldn't want a stranger to cum inside you.

"Condom' you gasp out as he strokes deep inside you. 'Oh shit. Sorry' He says. 'I got carried away.' He pulls out of you, leaving you feeling terribly empty, and you see him find his pants pocket and pull out a condom. You think the wrapper looks a little worn, and wonder for a second how long it's been in his wallet. He rolls it down in a well-practiced manner, and then positions himself behind you again. He teases at your entrance for a second to spread around some of your wetness, then starts to slide in slowly while you push your hips back to meet his. He continues on, slowly increasing his pace and going gradually harder. You're enjoying this position more than normal. Usually you'd need to use a vibrator to cum like this, and maybe it's his unique cock, but you're getting close without anything extra. You can feel the curve and large head putting pressure somewhere new inside you, and you feel pleasure building inside. His thrusts are now coming hard enough to almost lift your feet, and his hands are wrapped almost completely around your small waist. The feel of his hands on your skin and his rhythmic grunts of pleasure are enough to push you over the edge for you first orgasm. You gasp and cry out and your legs shake, going weak in the knees for a second. He slows his strokes gradually and pauses to let you catch your breath.

You realize in this position you're missing out on the best part; being able to see this man's glorious physique. You turn around to face him and kiss him, his still-hard cock resting on your belly. You lift yourself up and sit on the stool, leaning back against the wall and spreading your legs wide while he positions himself between them. He holds your legs up effortlessly and it's surprisingly comfortable when he slides back inside you. When he starts thrusting again you feel something different. 'Oh!' you exclaim, then 'Oh God!' more emphatically, and then you're swept away with the intense pleasure you've never fully felt before. His curved cock must be perfectly hitting your G-spot, something you've only ever felt hints of before.

It's a new kind of intense pleasure that overwhelms you, and you find yourself becoming aware that you're crying out loudly as you orgasm again. Isaac is moving like a machine now, and you can tell he's getting close. He's still stimulating you in such an amazing way and you feel your third orgasm building deep inside. You slide your hands up his now sweaty chest and rub his nipples. You're surprised when he instantly cries out and starts pulsing inside you. You reach a hand around his tight butt and hold him deep inside as he cums. You're not disappointed you didn't get to cum a third time, even though it felt like it was going to be the best one yet... Well maybe just a little disappointed, but you smile up at him, loving how you made him cum.

Isaac rests inside as your bodies hold tight together for a moment, then slowly slides out. You feel a warm wetness sliding out of you too and look down. The remnants of a condom encircle the base of his cock, but the fat head is bare. The condom broke and his cum is now spilling out of you. 'Oh, crap. Sorry.' He starts to apologize. 'It's okay, it's a safe day' you tell him, and stand up to kiss him, thanking him for the amazing time. As you kiss him deeply for a minute you feel his cock poking your stomach again. You forget these young guys can just go and go.

You're ready too, and you really want to chase that third orgasm. You realize you were getting quite loud at some point during your intense orgasm and you glance over at the shutters. With a little shock you think they seem more open than they were before. There may even be a dark shadow behind one. Isaac clearly wants to keep going, but if you mention it he'll probably get freaked out because he could lose his job. You could also just say you have to get home, and not mention there might be someone watching.
