he grabs you and pushes you against a wall as you both give each other devilish smiles. You trace his shirt slowly down to his waist as he rubs his dick against your wet pussy. He places his hands on your hips as you put your hand under his jeans and down below. You feel his hard erected dick and smile at him evilly. You slowly unzip his pants and then his jeans so that his horniness intensifies. He then rips your skirt off and your pants off and licks his lips at your pussy. He throws you onto the bed and as you land with a thud he pins your arms down next to you and he'd tease your pussy with his dick as you kiss him. You moan and pull him down as he penetrates your pussy. You sound a huge inhale as you press your titties against his chest waiting for him to penetrate deeper
