Relaxing in the room, I was suddenly stopped by an annoyed voice saying, "Aren't you leaving yet!?" It was supposed to be the first day of our promised jogging routine, but I was already feeling lazy and unmotivated. She insisted, "I'm doing my stretches, so hurry up and get ready!" as she started stretching right in front of me. Seeing her large breasts tightly wrapped in a snug sports bra, I couldn't resist grabbing and groping them from behind. She protested with a playful "Hey, come on~," but her half-hearted attempt to push me away felt gentle, hinting she wasn't entirely opposed. Encouraged, I kept massaging her breasts, feeling her face flush as she whispered, "Harder..."—prompting me to shift into full bare tit fondling. I savored the firmness of her hardened nipples and the soft, plump weight of her big tits, then slid my hands under her spats to squeeze her firm ass and feel the tightness of her pussy lips. Fully turned on, she took my rock-hard cock into her mouth, coating it with saliva before giving me an intense titty fuck. I yanked her spats down, slammed into her from behind, and pounded her hard and fast. Finally, she straddled me for a titfuck, riding my cock with her soft, pillowy breasts, and I erupted a massive load deep into her cleavage. A lazy day transformed into a passionate session of relentless big tit groping and sensitive, squirting titty-fuck sex.
