If her feet were sensitive to the touch, you deduce that her ass would treat her nicely while you recover. You slap he ass just as she wanted and she moans as you slow your pace a little; she doesn't notice but she demands you to do more slaps and to make them harder. You do just that: one hand swoops down and glides off of her cheek, making a ringing of flesh being tormented, followed by her lustful moans.
"Yeah, that's right. Uuhhmmmm. Moore. Do you like my fat ass? Do you like how- ah, it jiggles every time you- hmm, punish it? More! I want more!" You feel you upcoming orgasm fade to you disappointment, but at least you can last for longer while she is distracted. Your slaps become more frequent and harder as does her demands; you're worried that the people outside of your room could hear you. You start to fuck her harder and you can hear her ass cheeks clap from not only your hands but from your dick; her cheeks have grown a little bit more again. You can feel the warmth of her pussy through the condom and it becomes overwhelming as pleasure surges through you. You squeeze her buttocks and start rocking her hips which makes her silent, before she lets out a scream of pleasure. "Right there! Yes! Yes! Yes! Yes! I love cocks. I love cocks. I love dicks! They feel so good! Ah, uh huh, yeah!" Her feet are waving in the air again but they don't get in the way and you focus on slapping her to hopefully sedate her lust after her orgasm. You think about how massive her breasts must be and you hunch on top of her as she collapses onto the bed. You lift up her chest and fondle each tit in your hands and pound her ass from behind. You feel her pussy clench around you as you toy with her bulbous boobs and fat, perky nipples and she spasms: she just had her orgasm. You let out a little shout and you finally let out your load into the condom and she moans gratefully as you blast more than you ever had having sex with her, into her. The two of you collapse and pant, recovering your breaths.
"Oh Sarah, that was amazing." you whisper into her ear. If she doesn't spread the virus, maybe it wouldn't be so bad. But there was that infected person stil out there. She giggles in a giddy, ditzy, way.
"Silly, I'm Sandy, and it's always this good. Your dick is so hard, big, juicy, and hard — I love dicks but your's is best."
Fuck.
There was a knock at the door.
Double fuck.
"Room service for Brad and Sarah? Your dinner is ready."
"Ooh, did you get Sandy another dick?" She throws you off of her and giggles with excitement. You see that her hair has turned into a much lighter shade than before and that her bras will never hid the puppies you were squeezing — they were at least three times bigger than the woman you married — her lips have become fuller, pinker and they seem to be soft to touch, her eyes are duller in terms of intelligence but brighter with thrill and lust; there are tinted with pink and look shades brighter. If it wasn't for the fact that you saw first hand earlier what the transformation looked like, you would've believed that you just fucked with another woman. She gasps and you snap back to the situation. "Did you get Sandy a second dick for dinner? I get to have two dicks for dinner?"
Literally, double fuck.
Before you can tell her anything, she bounces of the bed — and you watch as her features bounce with her and each of her steps — as juices already start to drip and stain the carpet: she's ready for round two. Your semi-hard dick still has it's condom on and you feel fatigued, but this could be really dangerous really quickly. You get up as 'Sandy' reaches for the door.
