My older sister, who lives with me in the same room, looks serious at first glance, but she's actually a total slut! So of course her female friend is a slut too! My female friend came over to visit and seduced me as soon as my sister was gone! I couldn't help but get a boner when I saw her panties from the bunk bed! Of course she let me do it, so I thought I might as well... and secretly took off the condom and came inside her!
