I couldn't refuse when my wife's sister secretly seduced me... When I was in the kotatsu, the girl reached for my dick! Even though his wife is nearby, he slowly and thoroughly entangles his fingers and gives him a handjob! A lot of ejaculation in a 'semi-closed room' situation where only the lower half of the body is visible! Not satisfied with that, the girl hides in the kotatsu and asks for penetration...
