[Reducing Mosaic]DOCP-154 The story of the day I enjoyed secret sex with her best friend while she was away.

"Forget about that kid, go deeper...!" I was supposed to be living harmoniously with her, but who would have thought it would come to this... Her adorable friend she brought home. We were having a good time talking together, but as soon as she left the scene, her friend suddenly changed! She came over to my side, groping my crotch and seducing me...! Can I resist and stay true to her, or will I succumb to the taboo feelings and sink into the mire with this slutty friend...!!!
