Staying over at my beloved girlfriend's place, I borrowed her bathroom and unexpectedly encountered her roommate—an older sister figure. I couldn't help but be drawn to her undeniable big tits. With a sly grin, she suddenly started seducing me, overwhelming me with desire. While my girlfriend only allows protected sex, this older sister is completely okay with bareback and creampie—her willingness pushes me past my limits. Even with my real girlfriend nearby, I lose myself in the intense pleasure, unable to stop thrusting deep inside her.
