[M/F] Romance holiday

Hello, please find an extract of my first erotic short story- any constructive feedback is welcomed

As they raced up the hill they reached the garage of the hotel, there was a cut through to get to the lifts so that you could bypass the reception. As they we’re making there way to the lifts, Rob started to passionately kiss Martha, they couldn’t keep there hands of each other. Martha had a dark red wrap style dress on and her ample breasts were on the verge of busting out over her poorly fitted bra and tight dress. Rob leaned Martha against a car and was kissing her on her neck and making his way down to her slightly sunburnt breasts. She could feel how hard he was when rubbing her leg against him. Lost in the moment, Rob started to move his hand up the inside of Martha’s warm thigh, his fingers rubbing her wet juices over her black Lacey underwear. Martha was writhing with pleasure as the friction of her underwear rubbed over her clit that was absolutely throbbing. Just as Rob was about to insert his fingers inside her there was shouting from the entrance of the garage, ‘get a room you slut’
It was the scowling woman’s from the bar earlier, ‘she’s got a point’ laughed Martha, they had given the staff on security duty enough of a show as she tried to compose herself to make her way over to the lift. The blonde woman from the bar and her amused husband got in the lifts first and Martha and Rob waited for the lift to return for what felt like an eternity, they stepped in and Martha pressed the button for the 8th floor, it took all her control not to jump on Rob, her mind raced as she wondered what their first time of full intimacy would be like. She had had other lovers but never had this sexual chemistry or attraction with any of them- her body tingling with excitement of what was to come when they reached the room.
