"Him", you reply. "Maybe her later but I wanna start with him."
"Sounds good", she replies, and a few seconds later, "See you in a bit babe!"
You decide not to keep her waiting- for one thing, you're also super aroused right now. You find a cute sundress in your wardrobe and some panties, and put them on before adding some low-heeled shoes, and then leave your flat, take the elevator down and out of the building and walk to your girlfriend's flat.
When you reach her place and knock the door, the person who answers you is a young man. If you didn't know better you'd think he was your girlfriend's twin brother or something, but you feel just as attracted to him as you do to her. Your girlfriend- or perhaps boyfriend is more accurate- invites you in, shuts the door, and moves to kiss you. You kiss back and the two of you head to the bedroom hastily.
Once you're in there, you pull off your shoes and he removes his T-shirt, giving you a nice view of his slim toned body. You help him to pull off your sundress, and he removes his jeans before you both remove your underwear. His hard cock springs free and your pussy is revealed to him almost simultaneously.
He moves up toward you, his body seeming much larger than yours and arousing you with its firmness, and kisses down your neck. Your heart races from the sensation of his lips against your skin, but that's nothing to how it feels when he reaches one of your breasts and his mouth encircles your nipple. You moan softly in response- you've never felt so much like you're not a boy, and it's amazing! His warm wet mouth around your soft flesh and his tongue brushing over it is intoxicating, and between your legs your anticipation rises and you feel yourself moisten.
You carefully stroke his hair and mumble through your aroused moans, "I, mmmh... I wanna..." He looks up and you point downwards. Realising what you're gesturing at, he moves off you and gives you a view of his hard penis. "I don't wanna have all the fun," you say as you move down between his legs and carefully take his head into your mouth. You're surprised to find you actually kinda like the taste- it's warm and salty- and he groans and pants with pleasure as you suck on him. His hips seem to shake like he wants to thrust into your mouth, but he holds himself back politely.
After a while, he pulls you off him and says, "Do you wanna do it for real?"
"Fuck yeah," you reply. He moves you into position, lying you down on the bed and getting atop you. You spread your legs for him, your anticipation mounting, and shiver with pleasure as his cock head brushes against a sensitive spot at your crotch which you realize is your clitoris.
He pushes inside you slowly and you bite your lip at the feeling of being filled up. You've had sex as a man before, but it's a whole other world doing so as a woman. And god, he's so good- he slowly picks up the pace and his cock hits all the sweet spots inside you. What he does with his hands is magic too, as he carefully rubs and pinches your nipples, and moves one hand down to stroke your clit. Before long you're just moaning and whimpering with unadulterated pleasure, feeling him pound you harder and harder as you rapidly approach your climax.
At last you reach it, and you clench tightly around his cock reflexively, all rational thought clouded out by your body's instincts. Your arousal is inflamed by hearing him pant and moan in his deep voice, and even moreso when he cums inside you, his shaft twitching and seed shooting from it.
You both cuddle up close, exhausted but full of pleasure in the afterglow of your lovemaking.
