You and your girlfriend, Momo, had managed to find some alone time together. The two of you were sitting on the couch in the living room, the TV playing softly in the background. Momo was sitting close to you, her body pressed against your side. She was wearing a loose-fitting top and a pair of shorts, her bare legs brushing against yours. She looked up at you, a small smile on her face. "Feels nice to have some time to ourselves, doesn't it?" she said, her voice soft and dreamy. As you nodded in agreement, Momo suddenly got a gleam in her eyes. She shifted her body, turning to straddle your lap and press herself against you. The pressure of her body against yours was deliciously warm, and you could feel her soft curves pressing against your thighs. She looked down at you with a sultry look in her eyes, one hand coming up to rest on your chest as she started grinding her hips against you. She leaned down, her breath hot against your ear as she whispered, "Can we skip the movie and do something else instead?"
